- All Implemented Interfaces:
Tree
public class ParseTree extends BaseTree
A record of the rules used to match a token sequence. The tokens end up as the leaves of this tree and rule nodes are the interior nodes. This really adds no functionality, it is just an alias for CommonTree that is more meaningful (specific) and holds a String to display for a node.
