_findAllNodes void _findAllNodes(ParseTree t, int index, bool findTokens, ParseTree[] nodes): Undocumented in source. Be warned that the author may not have intended to support it.
descendants ParseTree[] descendants(ParseTree t): Undocumented in source. Be warned that the author may not have intended to support it.
findAllNodes ParseTree[] findAllNodes(ParseTree t, int index, bool findTokens): Undocumented in source. Be warned that the author may not have intended to support it.
findAllRuleNodes ParseTree[] findAllRuleNodes(ParseTree t, int ruleIndex): Undocumented in source. Be warned that the author may not have intended to support it.
findAllTokenNodes ParseTree[] findAllTokenNodes(ParseTree t, int ttype): Undocumented in source. Be warned that the author may not have intended to support it.
findNodeSuchThat Tree findNodeSuchThat(Tree t, Predicate!Tree pred): @uml Return first node satisfying the pred
getAncestors Tree[] getAncestors(Tree t): @uml Return a list of all ancestors of this node. The first node of list is the root and the last is the parent of this node.
getChildren Tree[] getChildren(Tree t): @uml Return ordered list of all children of this node
getDescendants ParseTree[] getDescendants(ParseTree t): @uml Get all descendents; includes t itself.
getNodeText string getNodeText(Tree t, InterfaceRecognizer recog): Undocumented in source. Be warned that the author may not have intended to support it.
getNodeText string getNodeText(Tree t, string[] ruleNames): Undocumented in source. Be warned that the author may not have intended to support it.
getRootOfSubtreeEnclosingRegion ParserRuleContext getRootOfSubtreeEnclosingRegion(ParseTree t, int startTokenIndex, int stopTokenIndex): @uml Find smallest subtree of t enclosing range startTokenIndex..stopTokenIndex inclusively using postorder traversal. Recursive depth-first-search.
isAncestorOf bool isAncestorOf(Tree t, Tree u): @uml Return true if t is u's parent or a node on path to root from u. Use == not equals().
stripChildrenOutOfRange void stripChildrenOutOfRange(ParserRuleContext t, ParserRuleContext root, int startIndex, int stopIndex): @uml Replace any subtree siblings of root that are completely to left or right of lookahead range with a CommonToken(Token.INVALID_TYPE,"...") node. The source interval for t is not altered to suit smaller range!
toStringTree string toStringTree(Tree t): @uml Print out a whole tree in LISP form. {@link #getNodeText} is used on the node payloads to get the text for the nodes. Detect parse trees and extract data appropriately.

toStringTree string toStringTree(Tree t, string[] ruleNames): @uml Print out a whole tree in LISP form. {@link #getNodeText} is used on the node payloads to get the text for the nodes.
