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
TreeVisitorAction	How to execute code for node t when a visitor visits node t.
TreeWizard.ContextVisitor

Class Summary

BaseTree	A generic tree implementation with no payload.
BaseTreeAdaptor	A TreeAdaptor that works with any Tree implementation.
CommonErrorNode	A node representing erroneous token range in token stream
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.
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.
RewriteRuleNodeStream	Queues up nodes matched on left side of -> in a tree parser.
RewriteRuleSubtreeStream
RewriteRuleTokenStream
TreeParser	A parser for a stream of tree nodes.
TreePatternLexer
TreePatternParser
TreeRuleReturnScope	This is identical to the ParserRuleReturnScope except that the start property is a tree nodes not Token object when you are parsing trees.
TreeVisitor	Do a depth first walk of a tree, applying pre() and post() actions we go.
TreeWizard	Build and navigate trees with this object.
TreeWizard.TreePattern	When using %label:TOKENNAME in a tree for parse(), we must track the label.
TreeWizard.TreePatternTreeAdaptor	This adaptor creates TreePattern objects for use during scan()
TreeWizard.Visitor
TreeWizard.WildcardTreePattern
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
