Describe the PR
This is a pretty old PR of mine which refactors the high-level execution logic of PMD. The new abstraction GlobalAnalysisListener (and its helper FileAnalysisListener) implements the listener pattern for an analysis. Violations and errors are the kinds of events that are forwarded to this listener. Renderers now use this API to receive these events and produce a report or output it it. With this design analysis does not necessarily produce a Report object, if that's not needed. I expect this is might be useful for IDE integrations.
SourceCodeProcessor is removed and its functionality merged into PmdRunnable. RuleContext is not analysis-global anymore, instead it provides API for rules to report violations on. Eventually I want rule implementations to have type-safe access to a RuleContext object, eg by making them implement
AstVisitor<RuleContext, Void>.This is part of a pretty long chain of local branches (first PR was #3085), which aim to
These branches currently culminate with the implementation of a Javadoc parser using these new APIs. Using TextDocuments we can also eventually support #693, and I actually have an ugly prototype in my branches. Another cool thing I've been working on is copy-paste detection based not on tokens but on ASTs, which gives much more precise results as CPD and could possibly be part of pmd 7 as a new PMD rule.
