public interface ParseTree extends SyntaxTree
An interface to access the tree of 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.

The payload is either a Token or a RuleContext object.

  • Method Details

    • getParent

      ParseTree getParent()
      Description copied from interface: Tree
      The parent of this node. If the return value is null, then this node is the root of the tree.
      Specified by:
      getParent in interface Tree

    • getChild

      ParseTree getChild(int i)
      Description copied from interface: Tree
      If there are children, get the ith value indexed from 0.
      Specified by:
      getChild in interface Tree

    • accept

      <T> T accept(ParseTreeVisitor<? extends T> visitor)
      The ParseTreeVisitor needs a double dispatch method.

    • getText

      String getText()
      Return the combined text of all leaf nodes. Does not get any off-channel tokens (if any) so won't return whitespace and comments if they are sent to parser on hidden channel.

    • toStringTree

      String toStringTree(Parser parser)
      Specialize toStringTree so that it can print out more information based upon the parser.
