Class DFACompiler<T>

Object

DFACompiler<T>

All Implemented Interfaces:

MethodImplementor

Direct Known Subclasses:

FindCompiler, MatchCompiler

public abstract class DFACompiler<T>
extends Object
implements MethodImplementor

A byte code compiler base class for generating methods using DFA. Method return either token from accepting DFA state, errorToken if syntax error or eofToken if eof.
