Class LookAhead

java.lang.Object

me.jaimegarza.syntax.model.parser.LookAhead

public class LookAhead
extends Object

~pojo class

When the parser table is generated with a LALR parser, a set of lookaheads is computed. This is similar to a follow set except that the lookahead is more fine grained than the coarse follow set. Lookaheads are associated to dots, not non-terminals. A lookahead is computed on a per state basis. A state is observed and the set of follow-like terminals is obtained, only on the c context of that state.
