• Move these classes into internal sub-packages, if possible. Or make this classes package-private.

Done

Everything that's done...

pmd-compat6 - we keep this as is, no additional change in this module

• net.sourceforge.pmd.util.filter.Filters
• net.sourceforge.pmd.Report#Report
• net.sourceforge.pmd.Report#addRuleViolation
• net.sourceforge.pmd.Report#addConfigError
• net.sourceforge.pmd.Report#addError

pmd-core

• now public API

  • net.sourceforge.pmd.lang.document.FileCollector
    • #getCollectedFiles and #getReporter are promoted to public API

• done - in some other way

  • net.sourceforge.pmd.renderers.AbstractAccumulatingRenderer#renderFileReport
    • the method is made final, so that it can't be overridden anymore in subclasses. That's how the AccumulatingRenderer works now.

• to be hidden

  • net.sourceforge.pmd.cache.AbstractAnalysisCache
  • net.sourceforge.pmd.cache.AnalysisCache
  • net.sourceforge.pmd.cache.AnalysisCacheListener
  • net.sourceforge.pmd.cache.AnalysisResult
  • net.sourceforge.pmd.cache.CachedRuleMapper
  • net.sourceforge.pmd.cache.CachedRuleViolation
  • net.sourceforge.pmd.cache.ChecksumAware
  • net.sourceforge.pmd.cache.FileAnalysisCache
  • net.sourceforge.pmd.cache.NoopAnalysisCache
  • whole package net.sourceforge.pmd.cache
  • net.sourceforge.pmd.lang.LanguageProcessor.AnalysisTask#AnalysisTask
    • also make net.sourceforge.pmd.lang.LanguageProcessor.AnalysisTask#withFiles internal, that's the other way to create a new AnalysisTask
    • Accessible through a InternalApiBridge

• net.sourceforge.pmd.util.log.MessageReporter (TODO: Rename to PmdReporter)

• Already in internal packages

  • net.sourceforge.pmd.util.log.internal.ErrorsAsWarningsReporter
  • net.sourceforge.pmd.util.log.internal.QuietReporter
  • net.sourceforge.pmd.util.log.internal.SimpleMessageReporter

• net.sourceforge.pmd.util.ResourceLoader

• net.sourceforge.pmd.cpd.Tokens#Tokens()

  • is hidden

• net.sourceforge.pmd.cpd.Tokens

  • is not anymore InternalApi, because it is used in public API: net.sourceforge.pmd.cpd.TokenEntry#getImage

• net.sourceforge.pmd.lang.rule.RuleTargetSelector#isRuleChain

  • removed, as it was only used in a unit test

• net.sourceforge.pmd.rules.RuleFactory ([core] Consolidate n.s.pmd.lang.rule package #4799 !!)

  • already made package private with the PR

• net.sourceforge.pmd.RuleSetReference ([core] Consolidate n.s.pmd.lang.rule package #4799 !!)

  • already moved into internal package with the PR

• net.sourceforge.pmd.RuleSetReferenceId ([core] Consolidate n.s.pmd.lang.rule package #4799 !!)

  • already moved into internal package with the PR

• net.sourceforge.pmd.RuleSets ([core] Consolidate n.s.pmd.lang.rule package #4799 !!)

  • already moved into internal package with the PR

• net.sourceforge.pmd.Report - made the following methods private

  • Report (ctor)
  • addRuleViolation
  • addConfigError
  • addError
  • Note: The class is moved with [core] Consolidate n.s.pmd.reporting package #4803 ...

• net.sourceforge.pmd.RuleContext

  • getRule() is package private
  • create(...) is moved to new InternalApiBridge
  • net.sourceforge.pmd.RuleContext#addViolationNoSuppress (not used?)
    • has been removed
    • See [java] Is it possible to disable SuppressWarnings and NOPMD filters? #2736 and [core] Force disable suppressions (PMD + CPD) #2896

• To be done after [core] Consolidate n.s.pmd.reporting package #4803 is merged:

  • net.sourceforge.pmd.lang.rule.ParametricRuleViolation ([core] Consolidate n.s.pmd.reporting package #4803 !!)
    • Maybe most of the constructors can be made package private. It's only created in RuleContext... this might need to stay internal API - maybe it can be moved into InternalApiBridge as well...
    • Should be made package private and added to the InternalApiBridge

• To be done after [core] Consolidate n.s.pmd.lang.rule package #4799 is merged:

  • net.sourceforge.pmd.RuleSet
    • applies(net.sourceforge.pmd.lang.document.FileId)
    • applies(net.sourceforge.pmd.Rule, net.sourceforge.pmd.lang.LanguageVersion)
    • These should be made package private and a InternalApiBridge class should be provided to make them accessible where needed.
  • net.sourceforge.pmd.RuleSetLoader#loadRuleSetsWithoutException
    • Should be made package private and added to the InternalApiBridge
  • net.sourceforge.pmd.RuleSetLoadException#RuleSetLoadException(net.sourceforge.pmd.RuleSetReferenceId, java.lang.Throwable)

  • should be made package private and accessed via a InternalApiBridge

• net.sourceforge.pmd.PMDConfiguration#getAnalysisCache

  • make package private

• net.sourceforge.pmd.PMDConfiguration#setAnalysisCache(AnalysisCache)

  • make package private
  • Note: the other setAnalysisCache method, which takes a String, is public API

• net.sourceforge.pmd.properties.PropertyTypeId

  • move into internal package

pmd-ant

• net.sourceforge.pmd.ant.Formatter
  • Note: the whole class can't be internal API, since this is part of the public ant api of PMD (see PMDTask). But the single methods annotated with InternalApi should be hidden

• net.sourceforge.pmd.ant.Formatter#start
• net.sourceforge.pmd.ant.Formatter#end
• net.sourceforge.pmd.ant.Formatter#isNoOutputSupplied
• net.sourceforge.pmd.ant.Formatter#newListener

  • should be package private
  • remove from ApexNode interface
• net.sourceforge.pmd.lang.apex.ast.ApexParser
  • should not be internal api, no reason why it should.
• net.sourceforge.pmd.lang.apex.multifile.ApexMultifileAnalysis#ApexMultifileAnalysis
  • should be package private. We need a InternalApiBridge to access it
• net.sourceforge.pmd.lang.apex.rule.design.AbstractNcssCountRule
  • should be package private
• net.sourceforge.pmd.lang.apex.rule.AbstractApexUnitTestRule
  • should be package private
• net.sourceforge.pmd.lang.apex.rule.internal.Helper (already internal)
  • no need for the annotation due to internal package

  • that's fine, nothing to change
• net.sourceforge.pmd.lang.java.rule.AbstractIgnoredAnnotationRule

• net.sourceforge.pmd.lang.java.types.ast.LazyTypeResolver
  • move into internal package
• net.sourceforge.pmd.lang.java.types.JMethodSig#internalApi
  • the method should be removed. We should explicitly downcast to the internal api interface where needed.

  • make package private
  • and add a InternalApiBridge class

pmd-jsp

• net.sourceforge.pmd.lang.jsp.ast.JspParser#getTokenBehavior
  • move into a InternalApiBridge
  • note: protected method tokenBehavior does the same...

  • no need for the annotation

pmd-modelica

• net.sourceforge.pmd.lang.modelica.ast.InternalModelicaNodeApi
