Class NTMapper

java.lang.Object
  danbikel.parser.NTMapper

public class NTMapper
extends Object

A class that provides a static method for mapping nonterminals, map(Symbol). This class uses an internal NonterminalMapper instance, the actual type of which is determined by the value of Settings.prevModMapperClass. If Settings.prevModMapperClass was not set (which should never happen, since that setting is part of the default settings provided with this package), then an instance of IdentityNTMapper is used.
