org.antlr.analysis.LL1DFA
public class LL1DFA
A special DFA that is exactly LL(1) or LL(1) with backtracking mode predicates to resolve edge set collisions.
Field Summary |

LL1DFA(int decisionNumber,
NFAState decisionStartState,
LookaheadSet[] altLook)
From list of lookahead sets (one per alt in decision), create an LL(1) DFA. |

LL1DFA(int decisionNumber,
NFAState decisionStartState,
MultiMap<IntervalSet,java.lang.Integer> edgeMap)
From a set of edgeset->list-of-alts mappings, create a DFA that uses syn preds for all |list-of-alts|>1. |
