NAME

Parse::Eyapp::Node - The nodes of the Syntax Trees

SYNOPSIS

use Parse::Eyapp;
use Parse::Eyapp::Treeregexp;

METHODS

The Parse::Eyapp::Node objects represent the nodes of the syntax tree. All the node classes build by %tree and %metatree directives inherit from Parse::Eyapp::Node and consequently have acces to the methods provided in such module.

Parse::Eyapp:YATW Methods

Parse::Eyapp:YATW objects represent tree transformations. They carry the information of what nodes match and how to modify them.

TREE MATCHING AND TREE SUBSTITUTION

See the documentation in Parse::Eyapp::MatchingTrees
