Parser.setBuildParseTree介绍

[英]Track the ParserRuleContext objects during the parse and hook them up using the ParserRuleContext#children list so that it forms a parse tree. The ParserRuleContext returned from the start rule represents the root of the parse tree.

Note that if we are not building parse trees, rule contexts only point upwards. When a rule exits, it returns the context but that gets garbage collected if nobody holds a reference. It points upwards but nobody points at it.

When we build parse trees, we are adding all of these contexts to ParserRuleContext#children list. Contexts are then not candidates for garbage collection.
