2025-11-10 ------ omnetpp-6.3.0 released ------

2025-10-21 Andras Varga

* Follow cPar and cParImpl changes that allow the target parameter pointer

to propagate to NED functions.

2025-07-24 Andras Varga

* cSingleFingerprintCalculator: Implemented "b","g" fingerprints. In cEvent

and cMessage, parsimPack() was updated to support the new fingerprint

ingredients.

2025-07-17 Andras Varga

* parsimPack()/parsimUnpack() functions are no longer protected by #ifdef

WITH_PARSIM, allowing calls even if the simulation kernel was compiled

without parsim support (previously threw "parsim not available" exceptions).

2025-07-17 Andras Varga

* cCommBuffer classes moved here from parsim/, to make them available even

if the simulation kernel was compiled without parsim support. These classes

do not depend on parsim code, and have uses outside parallel simulation

(e.g. fingerprint).

2025-09-22 Andras Varga

* DemuxFilter: Implemented getDemuxLabel().

2025-07-14 ------ omnetpp-6.2.0 released ------

2025-07-09 Andras Varga

* cComponent: emit(): refine error message for undeclared signals.

Include NED type name in the error message. This is important because a

module might call emit() on *another* module, and the error message

previously only contained the context module, and not the one on which

the emit() was called.

2025-06-05 ------ omnetpp-6.2.0pre1 released ------

2025-04-18 Andras Varga

* cTopology: implemented extractFromNetwork() overload taking an std::function.

2025-03-21 Andras Varga

* cLCG32, cMersenneTwister: implemented str() to make seed/state visible at runtime.

2025-02-24 Levente Meszaros

* Added separate catch case for cTerminationException in order to

allow the debugger determining the type_info of the exception.

This is needed to allow lldb to skip the C++ throw exception breakpoint.

2025-02-21 Levente Meszaros

* Implemented getTerminationExceptionTypeInfoPointer().

2025-02-19 Andras Varga

* cArray: Fixed #1313 "cArray::addAt() throws segmentation fault when

using cArray::setCapacity()"

2025-02-10 Andras Varga

* Fixed #1308 "Error at network deletion after simulation finished"

<!> (omnetpp::cChannel)channel: Fatal: Direct deletion of a channel

object is illegal, use cGate's disconnect() or reconnectWith() instead;

ABORTING -- during network cleanup

This was due to cGate::getDisplayString() accidentally creating a

dangling channel object (for a gate that's not connected as a source

gate).

2025-01-14 Attila Torok

* cAbstractTextFigure: implemented getTextExtent() and getFontAscent().

2025-01-09 Attila Torok

* cLabelFigure: Make getBounds() take angle into account.

2024-12-10 Andras Varga

* Fix duplicated call to channels' preDelete() method during network

teardown.

2024-12-10 Andras Varga

* cModule: fix preDelete() being called multiple times during deleting

a network or compound module.

2024-12-13 Andras Varga

* cConfiguration: Fix crash caused by reading a config option before

having a cSimulation installed (i.e. when getSimulation()==nullptr).

Fixes #1271.

2024-10-08 ------ omnetpp-6.1.0 released ------

2024-09-27 Attila Torok

* Fix: Make the MPI implementation of parsim actually get built in

when available and requested, by adding missing inclusions of

platdep/config.h before any WITH_MPI (or WITH_PARSIM) macro usages.

2024-09-09 Andras Varga

* Added the "print-instantiated-ned-types" and "print-unused-parameters"

config options

2024-09-10 Andras Varga

* cEnvir: added getOutputStream()

2024-07-12 Levente Meszaros

* Fixed incorrectly sharing double parameters that have NaN values.

When setting one with a deep parameter assignment the other was also set.

* SimTime: better error messages in arithmetic operations involving cPars

2024-06-10 Andras Varga

* NED functions: Documentation strings proofread

2024-05-28 Andras Varga

* SimTime: adjust error messages

- Use "simtime_t:" prefix.

- Use "Cannot represent x" instead of "x cannot be represented" or "Cannot convert x"

2024-03-25 Andras Varga

* SimTime: Follow/implement changes described in include/omnetpp/ChangeLog.

2024-05-06 Andras Varga

2024-04-07 Andras Varga

* cEnvir: Follow/implement changes described in include/omnetpp/ChangeLog.

2024-04-04 Andras Varga

* cResultRecorder: resolve "enumname" attr in the @statistic to "enum"

Given the following C++ code:

enum LinkState {UP, DOWN, FAULTY};

Register_Enum(LinkState, (UP, DOWN, FAULTY))

and NED:

@statistic[linkState](record=vector; enumname=LinkState);

The recorded vector will have the following attributes in the .vec file:

attr enumname LinkState

attr enum "UP=1, DOWN=2, FAULTY=3"

which can be utilized by the SeqChart, chart templates, etc.

If enumname is specified, the enum MUST exist and be registered.

Only one of the enum and enumname attrs may be present in a @statistic.

2024-04-04 Andras Varga

* cEnum cosmetics

2024-03-20 Levente Meszaros

* cSimulation: set CTX_SCHEDULER context in the takeNextEvent() method

that invokes the scheduler.

2024-03-20 Levente Meszaros

* Print the qualified name of instantiated NED modules; enable with

the -DPRINT_MODULE_TYPES_USED compiler option.

This is an internally used (non-public) feature, used by the automatic

project feature dependency discovery mechanism of INET.

Recompile OMNeT++ to enable/disable it.

2024-03-19 Andras Varga

* cPar: implement new resetEvalContext=true argument of parse().

If resetEvalContext=true, parse() now sets the evaluation context

to the owner component.

This fixes #1132 "Pattern assignment causes subsequently assigned parameter

expression to be evaluated in wrong context".

It was chosen to add the restoring code into parse(), because it is

called at multiple places, and almost always the intention is that the

expression should be evaluated in the context of the component that owns

the parameter.

include/omnetpp/ChangeLog.

2024-01-10 Andras Varga

* cResultFilter: Implement removeDelegate(), described in include/omnetpp/ChangeLog.

2024-01-18 Andras Varga

* cComponent: removeListener(): Keep order of listeners

2023-02-09 Andras Varga

* cValue: use UnitConversion::formatQuantity()

2023-01-16 Andras Varga

* cXMLParImpl, etc: made it possible to assign XML data to NED "object" parameters

Example:

**.config = xmldoc("config.xml")

Motivation: INET contains several NED parameters of type XML which we'd

like to port to JSON. However, we don't want to break existing models. If

a parameter of type "object" accepts both XML amd JSON, then we cam

achieve that by changing the types of those parameters from "xml" to

"object", and enhancing the module C++ implementation to be able to

process both. Then it would be up to the user when they port existing

models (omnetpp.ini etc) from XML to JSON data.

Details:

cObjectParImpl only accepts cOwnedObject and wants to own them, so we

need to make cXMLElement subclass from cOwnedObject, and duplicate the

XML trees from the XMLDocCache when assigning the parameters. Hence the

following changes:

- cXMLElement changed to subclass from cOwnedObject

- its tagName is now stored in the object name (cNamedObject)

- added dup(), dupTree()

- use dupTree() in the xmldoc() and xml() NED functions

- cXMLParImpl: make act like cObjectParImpl, i.e. own its cXMLElement

- cXMLParImpl: if it would not be able to take() the object (owner is

not a soft owner, see isSoftOwner()), it calls dupTree() to clone

it -- this is needed for assignent of XML params among themselves

in NED to work (like foo=xml(...); bar=foo;) like it did before.

(Needed for backward compatibility in INET.)

- XMLDocCache now also owns the XML trees

cXMLParImpl code is now very similar to cObjectParImpl.

Further low-hanging fruits:

- cXMLElements ctor and setters could be made public

- XmlDocCache may be cleared at any time, because all XML trees

it returns are now duplicated.

2023-01-16 Andras Varga

* cObjectParImpl: use inherited&refined deleteOld() instead of

deleteExpression(). cParImpl::deleteOld() implies deleting the expression,

plus more like clearing the srcLoc info.

Move deleteObject() call out of doSetObject(), and into deleteOld()

2023-09-28 Andras Varga

* cBoolParImpl,etc: factored out duplicated deleteOld() functions to

base class

2023-01-10 Andras Varga

* cPar to remember the file/line location where it was assigned from

New cPar methods:

- getSourceLocation()

- getBaseDirectory()

Latter is just a new getter for an existing private field.

2022-03-25 Andras Varga

* Added componentId() NED function

2022-11-21 Andras Varga

* Fix cDisplayString::doParse() bug remaining after d8ce17e5

This fixes envir/qtenv_displaystringaccess_1.test

2022-08-01 Attila Torok

* cDisplayString: doParse(): Also swallow the trailing backslash.

To make it consistent with the disappearing mid-string backslashes. The

trailing one remaining there was probably accidental.

2021-07-28 Andras Varga

* cDisplayString: Don't split values on commas inside ${...}

expressions while parsing.

And don't escape them when assembling back into a string. Also

considering the $$ escape sequence.

2022-05-16 Attila Torok

* Use C++ headers instead of C ones, e.g. <cstdlib> instead of <stdlib.h>

2022-05-21 Andras Varga

* SimTime: initialize powersOfTen[] statically

2022-05-09 Andras Varga

* cKSplit: Follow adding const modifiers.

2022-05-10 Andras Varga

* CodeFragments: Implement storing src code too, for debug purposes

2024-02-01 ------ omnetpp-6.0.3 released ------

2024-02-01 Rudolf Hornig

* fix #973: handle cPar::setValue() for double values correctly

2024-01-10 Andras Varga

* Fix cLCG32 regression (self-test failure) introduced in omnetpp-6.0pre13

2024-01-09 Rudolf Hornig

* Performance: improve cModule::isSimple() speed by replacing dynamic_cast

usage by use of virtual methods.

2024-01-05 Rudolf Hornig

* Performance: In cTemporaryOwner, create base of class cSoftOwner with empty

name instead of "tmp".

2024-01-05 Rudolf Hornig

* Performance: Speed up the cMessage::isStale() call by avoiding a dynamic_cast.

It is needed because isStale() is called at least once on every message

delivery,

2024-01-09 Rudolf Hornig

* Performance: cSoftOwner: avoid pre-allocating array for child objects as most

of the time it is not needed.

2023-10-06 ------ omnetpp-6.0.2 released ------

2022-10-25 Attila Torok

* Fix build with DEVELOPER_DEBUG defined

2022-04-21 Andras Varga

* Fix missing initialization of some result filters

2023-06-06 Zoltan Bojthe

* cValueArray::asStringVector(): Remove unnecessary back and forth

conversions. The original code converted std:string --> cstring -->

std::string.

2023-07-17 Zoltan Bojthe

* cDatarateChannel: fixed issue 1012: clear finished transmissions from

txList.

2023-09-05 Andras Varga

* Fix #972 "intuniform() has broken bounds check"

intuniform(rng, std::numeric_limits<int32_t>::min(), std::numeric_limits<int32_t>::max())

resulted in "Interval is greater than RNG range" error due to wrong

comparison.

2023-08-22 Andras Varga

* cEventHeap: added checkHeap(). Not called anywhere, but available in case

FES debugging is needed.

2023-08-18 Andras Varga

* cEvent: disallow changing the arrival time and scheduling priority

when scheduled. They are part of the comparison key, so changing them

could change event ordering i.e. break the heap data structure of the

FES (cEventHeap).

setPriority(): check if event is scheduled, and throw exception if so.

setArrivalTime(): it is invoked quite often (on average at least once

per simulation event), so we use ASSERT() in order not to impact runtime

performance in release mode builds

2023-04-16 Andras Varga

* Fix startup error complaining about arg count of hypot()

<!> Error during startup: Register_Function() or cFunctionType: attempt

to register function "hypot" with wrong number of arguments 2, should be

* Fix fgets/fread "unused result" warnings

2023-04-06 Andras Varga

* Work around the fact that C++ doesn't allow throwing from destructors.

Introduced a panic() function and ASSERT_DTOR() instead.

2023-03-30 Andras Varga

* Fix warnings.

2022-09-01 ------ omnetpp-6.0.1 released ------

2022-08-26 Andras Varga

* Fix: proper namespace resolution for C++ types in @signal declarations.

This fixes signals_namespace1.test.

2022-08-17 Andras Varga

* Feature: added cProperty::getValueOriginFile(), getValueOriginType()

2022-06-17 Attila Torok

* Check for context component in all built-in NED functions that need it,

and throw an exception if there is none, instead of just crashing. This

is needed when evaluating expressions in display strings of messages.

2022-05-18 Attila Torok

* build: Disable implicit make rules by setting .SUFFIXES to empty

* Fix build by including <memory> for std::unique_ptr

2022-04-11 ------ omnetpp-6.0 released ------

2022-04-07 Andras Varga

* intuniform(): ensure range (b-a) is supported by the RNG; and avoid

spurious signed<->unsigned conversions which are supposed to be unspecified behavior.

2022-04-07 Andras Varga

* intuniform()/intuniformexcl): enforce a<=b or a<b

2022-04-06 Andras Varga

* cDynamicExpression: fix memory leak

2022-04-05 Andras Varga

* cKSplit: quick fix for memory leak in iteratorToCell()

2022-04-05 Andras Varga

* Reworked the initialization of the global cSoftOwner instance

globalOwningContext, due to issues found by UndefinedBehaviorSanitizer.

The problem was that globalOwningContext sort of wanted it insert itself

into its own child list while being constructed. It sort of worked but

the sanitizer sniffed out something was off.

The reworked solution employs a separate dedicated constructor which

avoids the owningContext->doInsert(this) call. internal::Void is a type

solely made to distinguish the dedicated constructor from other

constructors by giving it a different signature.

2022-04-05 Andras Varga

* Fix invalid value for LogLevel error from sanitizer

2022-03-19 Andras Varga

* Resolve lifecycle listener crash on shutdown.

2022-04-05 Andras Varga

* Replace memcpy() with std::copy_n(), to avoid calling memcpy() with

nullptr as 2nd arg, even with size=0.

2022-04-05 Andras Varga

* SimTime: avoid overflow in fillPowersOfTen()

2021-12-07 Andras Varga

* Result recorders: suppressed the ", vector" suffix from titles of

vector results. Also "histogram" and "stats". They don't need to be added,

as they are obvious, they simply echo the result item type.

2021-11-30 Andras Varga

* cResultRecorder: save display names and recording mode as result

attributes and "recordingmode", "moduledisplaypath".

2021-12-03 Andras Varga

* Move displayName field from cModule to cComponent

2021-11-25 Andras Varga

* cModule: fix: allow accessing module parameters from the "display-name"

config options.

2021-11-25 Andras Varga

* cConfiguration: Allow expressions in config option values to use

NED operators, module parameters and other NED expression features.

Immediate motivation: to be able use e.g. index in display-name:

**.app[0..3].display-name = "cbr-" + string(index)

2021-11-17 Andras Varga

* Result filters: Let the "count" and "sum" filter to record an

initial zero value.

- reuse cResultFilter::getInitialDoubleValue() for that

- timestamp must be the end of the warmup period, otherwise plot will lie

- emit after network building is done

- dynamically created modules must be taken into account

2021-11-24 Andras Varga

* SumPerDurationFilter: fix getSumPerDuration() behavior when invoked

during warmup period.

2021-11-08 Andras Varga

* cModule: displayName fix: getDisplayName() docu promises nullptr if unset

2021-11-04 Andras Varga

* cPar: Implemented isMutable() and the mechanism behind the new @mutable

property. @mutable may annotate module/channel parameters in NED, and has

the effect that non-mutable parameters (those without @mutable) cannot be

changed at runtime. It is recommended to only mark those parameters with

@mutable whose change actually takes effect during simulation, e.g. are

handled in handleParameterChange() methods in simple modules. The presence

of @mutable conveys the info which parameters can be tweaked to users of the

module.

Add parameter-mutability-check=false to omnetpp.ini to disable the check

for models that don't have the necessary @mutable annotations added.

2021-07-11 Andras Varga

* Follow change: moved internal classes to the omnetpp::internal namespace.

2021-11-02 Andras Varga

* Nits related to ownership handling:

- cObject::yieldOwnership() shouldn't crash in the "throw" statement

when newOwner==nullptr

- Set name of cTemporaryOwner objects to "tmp"

- Set name of globalOwningContext object to "globalOwningContext"

- etc.

2021-11-04 Andras Varga

* Introduced cValueContainer as common base class for cValueHolder,

cValueArray, cValueMap.

2021-11-02 Andras Varga

* cValueMap/cValueArray: revert dup() to behave the same way

cArray/cQueue does, i.e. only duplicate those objects that are

owned by the cloned container. This doesn't make much of a difference,

but some NED expressions that have been accepted now cause an error.

You need to dup the VERY object that belongs to some other owner --

dupping its container is NOT good any more. For example:

foo = {};

bar = dup([foo,foo]); // error

bar = [dup(foo), dup(foo)] // OK

2021-11-04 Andras Varga

* cObjectParImpl: added hint to "not owner" error message: "Try cloning it

using the dup() function!"

2021-11-04 Andras Varga

* Make unused parsimPack()/parsimUnpack() to be less of a noise

2021-11-03 Andras Varga

* getModuleByPath() / findModuleByPath() moved to cComponent

2021-11-03 Andras Varga

* cResultFilter/cResultRecorder: suppress expected warnings

2021-11-01 Andras Varga

* cObjectParImpl: More thorough check of the assigned content

wrt object ownership. Only fully owned cOwnedObjects are allowed.

2021-11-01 Andras Varga

* Added the expr() operator to NED. expr() can be used to specify

an expression with free variables. For example, assigning expr(x+y)

to a module parameter of type object allows the module implementation

to query the expression (it will be a cOwnedDynamicExpression object),

bind the free variables (e.g. x=3,y=2), and evaluate it. The expr()

operator is useful for e.g. implementing arbitrary packet filters.

* Added the new cOwnedDynamicExpression class, needed for expr().

2021-10-27 Andras Varga

* Added cValueHolder.

* cValueArray, cValueMap: Fix: errors for stored non-cObject pointers

2021-10-18 Andras Varga

* Fix call to wrong (deprecated) cResultFilter::init() method in

StatisticSourceAstTranslator.

2021-10-11 Andras Varga

* Added MergeFilter, a cResultFilter that allows multiple inputs,

and multiplexes them onto its singe output. It is available (as the

merge() function) in the source= part of @statistic, but not in the

record= part.

2021-10-08 Andras Varga

* Follow change: cResultFilter, cResultRecorder init() args merged

into a Context struct.

2021-10-06 Andras Varga

* Follow changes: Introduction of txid_t and msgid_t; changes in the cRNG

interface.

2021-09-23 Andras Varga

* Component parameters (specially JSON values) made more editable

2021-09-30 Andras Varga

* sim_std.msg: removed some @descriptor(readonly) annotations

2021-09-30 Andras Varga

* sim_std.msg: fix: simtime_t fields were not editable.

Also made other @opaque classes editable: cFigure::Point,

cFigure::Rectangle, cFigure::Transform, cFigure::Color, cFigure::Font

2021-09-22 Andras Varga

* DemuxFilter: move demux label to the front of the result name string

2021-09-22 Andras Varga

* Fix: according to its descriptor, cObject didn't have a "name" field

2021-06-09 Attila Torok

* cSimulation: Add sanity check to prevent reentrant event execution

2021-09-13 Andras Varga

* Fix bug introduced in 6.0pre12: "undisposed object" message didn't

contain the full path of parent module, only its name.

2021-07-29 Andras Varga

* cProperty: implement changes, see include/ChangeLog for details.

2021-07-16 Andras Varga

* sim_std.msg: added @toValue()/@fromValue annotations

2021-07-20 Andras Varga

* cClassDescriptor: added getFieldValue()/setFieldValue() to allow

accessing fields using cValue

2021-07-08 Andras Varga

* cValue changed to hold any_ptr instead of cObject (see include/ChangeLog

for details).

2021-07-17 Andras Varga

* cPar: added cValue-based generic access: getValue(), setValue()

021-07-08 Andras Varga

* cHistogram: added str() to Bin, and use it in sim_std.msg

2021-07-07 Rudolf Hornig

* build: copy sim_std_m.h to the include/omnetpp directory as it is

now #included into <omnetpp.h>

2021-07-06 Andras Varga

* sim_std.msg adjustments (over multiple commits

- cplusplus(cc) part: move stuff from .h to .cc because it's only needed

by the class descriptors

- mark non-polymorphic classes with @polymorphic(false); this results in

simpler toAnyPtr() code (i.e. without the dynamic_cast part)

- cResultListener inheritance fixed to match reality

- use @castFunction(false) to turn off generating fromAnyPtr/toAnyPtr

functions for some classes that have it defined elsewhere

- wrong base class was given for a few classes

- StringVector was unused, removed

2021-07-06 Andras Varga

* Port the codebase to any_ptr:

- "if (p)" changed to "if (p != nullptr)" everywhere, because any_ptr

intentionally has no bool conversion, but can be directly compared

against nullpr.

- use fromAnyPtr()/toAnyPtr() everywhere for conversion from/to any_ptr

2021-06-28 Andras Varga

* Follow change: cClassDescriptor now uses any_ptr instead of void*.

2021-06-23 Andras Varga

* Added implementation of any_ptr.

2021-07-01 Zoltan Bojthe

* cValueArray: add asIntVectorInUnit(), asDoubleVectorInUnit()

functions

2021-07-01 Zoltan Bojthe

* cValueArray: fixed copy-paste bug (type mismatch)

2021-06-23 Andras Varga

* Error messages reworded to be more precise:

"Cannot evaluate expression for parameter '%s'" --> "Cannot assign

parameter '%s'"

The old message was misleading, because often the expression itself evaluates

just fine, only the result is of the wrong type and cannot be assigned to

the parameter.

2021-06-07 Attila Torok

* Add proxy class descriptor for WATCH_[OBJ|PTR] to avoid crashes

The original solution involving:

virtual cClassDescriptor *cWatch_cObject::getDescriptor() const override

{return r.getDescriptor();} didn't work because the cWatch subclasses

lied that they themselves can be described by the descriptors of the

watched objects, which is not true.

And since there is often a cast through a void* in the descriptor APIs,

this mismatch went unnoticed, and operated essentially as a

reinterpret_cast, so mostly garbage was shown on the GUI as field values,

until eventually a crash occurred.

See test/anim/watch for an example.

2021-06-23 Andras Varga

* cModule: implemented addSubmodule() method

2021-06-23 Andras Varga

throughout the library.

2021-06-12 Andras Varga

* Follow changes in 'include/': added opp_pooledstring, opp_staticpooledstring

2021-06-13 Andras Varga

* cParImpl::parse() to store the expression's origin (file:line) in

cDynamicExpression so we can report it on evaluation errors.

2021-06-15 Andras Varga

* cRuntimeError: Implemented ctor for helping chaining exceptions

2021-06-15 Andras Varga

* cException modernized

2021-06-09 Andras Varga

* Implemented cConfiguration::KeyValue::getSourceLocation(),

so we can report location for parse errors in values coming

from ini files.

2021-06-18 Andras Varga

* cModule: simplify storing fullPath.

2021-06-18 Andras Varga

* cNamedObject: fix setName(getName())

2021-06-13 Andras Varga

* nedfunctions: get() NED function refined

2021-06-17 Andras Varga

* Follow header change: more methods made const in cPatternMatcher,

cMatchExpression and cTopology

2021-06-17 Andras Varga

* Fix: @omittedTypename didn't work if interface was not in the

* cValueArray, cValueMap: dup() to make an "even deeper" copy (clone

ALL objects). This is necessary for the following NED to work:

object a = {};

object b = dup([a]);

* nedfunctions: added get(), size(), dup() NED functions

* nedsupport: search for function/methods by the number of args

On one hand, this allows overloads by the number of args.

On the other hand, we cannot be as specific with error messages as

before. Instead of

"NED function '%s' expects %d arguments",

we'll report

"A '%s' function that accepts %d argument(s) was not found",

regardless of whether a function with that name but accepting a different

number of args exists or not.

* cNedFunction: added search by name AND accepted number of args

New functions:

- bool acceptsArgCount(int argCount)

- static cNedFunction *find(const char *name, int argCount)

- static cNedFunction *get(const char *name, int argCount)

* NED: implemented Universal Function Call Syntax

f(x,..) and x.f(...) are now equivalent. All NED functions that have at

least one argument can be used with the method syntax as well.

See https://en.wikipedia.org/wiki/Uniform_Function_Call_Syntax

* Allow 'object' as NED function arg type and return type

Disallow objects shared among parameters, because we don't know their

lifetimes.

Example:

object a = [1,2,3];

object b = a;

then set 'a' to nullptr --> accessing 'b' would crash!

* NED builder: allow the body of a parametric submodule to assign

apparently nonexistent parameters.

Example:

app: <default("FooApp")> like IApp {

parameters:

address = parent.address;

sleepTime = 1s;

}

If FooApp has a sleepTime parameter but IApp does not, then running with

the defaults is fine, but changing to another IApp type that does NOT

have a sleepTime parameter will stop the simulation with an error.

Solution: inside a parameteric submodule type, we simply ignore parameter

assignments that assign nonexistent parameters.

* NED builder: fix parametric channel type with type given as default

expression. The expression text was mistakenly interpreted as parameter name.

Example:

a.out++ --> <default(channelType+"")> like IFooChannel --> b.in++;

It would give the following error:

Error: Unknown parameter '"bubu"+channelType+""'

* nedsupport: give name strings to cValueArray and cValueMap objects

created for JSON arrays and maps: "array%d", "map%d". This can help

identify them in error messages, etc.

* cValueMap: fix copy ctor and dup()

2021-06-09 Andras Varga

* cValue: operator==() added

2021-06-08 Andras Varga

* cDynamicExpression: fix an ownership issue during evaluation

2021-06-09 Andras Varga

* cComponentType: delete shared cParImpl instances at the end of the

simulation. Previously they were only deleted on program exit.

* nedsupport: exists() NED operator to accept more forms.
