Examples of org.antlr.runtime.tree.CommonTree

org.antlr.runtime.tree.CommonTree
A tree node that is wrapper for a Token object. After 3.0 release while building tree rewrite stuff, it became clear that computing parent and child index is very difficult and cumbersome. Better to spend the space in every tree node. If you don't want these extra fields, it's easy to cut them out in your own BaseTree subclass.
