Detailed Description

This is the regexp node builder's interface. The classes that build parse tree nodes for regular expressions found in the lexical section must implement this interface in order to be able to be notified by the parser when a regualr expressino was recognized in he input grammar.

All the methods receive, besides arguments specific to the node's kind, an object of type Position that indicates the position inside the input file where the expression has been identified.
