Interface Summary

Tree	What does a tree look like? ANTLR has a number of support classes such as CommonTreeNodeStream that work on these kinds of trees.
TreeAdaptor	How to create and navigate trees.
TreeNodeStream	A stream of tree nodes, accessing nodes from a tree of some kind

Class Summary

BaseTree	A generic tree implementation with no payload.
BaseTreeAdaptor
CommonTree	A tree node that is wrapper for a Token object.
CommonTreeAdaptor	A TreeAdaptor that works with any Tree implementation.
CommonTreeNodeStream	A buffered stream of tree nodes.
DOTTreeGenerator	A utility class to generate DOT diagrams (graphviz) from arbitrary trees.
DoubleLinkTree	A generic doubly-linked tree implementation with no payload.
ParseTree	A record of the rules used to match a token sequence.
RewriteRuleElementStream	A generic list of elements tracked in an alternative to be used in a -> rewrite rule.
RewriteRuleSubtreeStream
RewriteRuleTokenStream
TreeParser	A parser for a stream of tree nodes.
TreeRuleReturnScope	This is identical to the ParserRuleReturnScope except that the start property is a tree nodes not Token object when you are parsing trees.
UnBufferedTreeNodeStream	A stream of tree nodes, accessing nodes from a tree of ANY kind.

Exception Summary

RewriteCardinalityException	Base class for all exceptions thrown during AST rewrite construction.
RewriteEarlyExitException	No elements within a (...)+ in a rewrite rule
RewriteEmptyStreamException	Ref to ID or expr but no tokens in ID stream or subtrees in expr stream
