ParseTree

An interface to access the tree of {@link RuleContext} objects created * during a parse that makes the data structure look like a simple parse tree. This node represents both internal nodes, rule invocations, and leaf nodes, token matches.

<p>The payload is either a {@link Token} or a {@link RuleContext} object.</p>

interface ParseTree : SyntaxTree {

ParseTree getParent();

void setParent(RuleContext parent);

ParseTree getChild(int i);

T accept(ParseTreeVisitor!U visitor);

Variant getText();

string toStringTree(InterfaceRecognizer parser);

}

accept T accept(ParseTreeVisitor!U visitor): The {@link ParseTreeVisitor} needs a double dispatch method.
getChild ParseTree getChild(int i): @uml @override
getParent ParseTree getParent(): @uml @override
getText Variant getText(): Undocumented in source.
setParent void setParent(RuleContext parent): Undocumented in source.
toStringTree string toStringTree(InterfaceRecognizer parser): Specialize toStringTree so that it can print out more information based upon the parser.

getSourceInterval Interval getSourceInterval(): @uml Return an {@link Interval} indicating the index in the {@link TokenStream} of the first and last token associated with this subtree. If this node is a leaf, then the interval represents a single token and has interval i..i for token index i.
