perform

public void perform(AbstractNode root)

Here is where semantic analysis happens. The code below will run this visitor on the tree. If you want to split the work up, then make other visitors and run them from perform

Overrides:

perform in class ReflectiveVisitor

defaultVisit

public void defaultVisit(java.lang.Object o)

Pass the visitor down

Overrides:
