LookaheadEventInfo

This class represents profiling event information for tracking the lookahead depth required in order to make a prediction.

Constructors

this
this(int decision, ATNConfigSet configs, int predictedAlt, TokenStream input, int startIndex, int stopIndex, bool fullCtx)

Constructs a new instance of the {@link LookaheadEventInfo} class with the specified detailed lookahead information.

Members

predictedAlt
int predictedAlt;

the outermost alt shown for a rule; left-recursive rules have user-level alts that differ from the rewritten rule with a (...) block and a (..)* loop.
