From debugging my Annotator instance, I only see invocations for all Psi-elements.
This is in contrast to the information here: http://confluence.jetbrains.com/display/IDEADEV/Developing+Custom+Language+Plugins+for+IntelliJ+IDEA?focusedCommentId=51944660&#DevelopingCustomLanguagePluginsforIntelliJIDEA-SyntaxHighlightingandErrorHighlighting
...which states "When the file is changed, the annotator is called incrementally to process only changed elements in the PSI tree."
Can someone shed some light on this ?
Does this depend on the specific AST-node structure maybe ?
