- 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
rint out a whole tree in LISP form. {@link #getNodeText} is used on the
node payloads to get the text for the nodes.
