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, size_t startIndex, size_t stopIndex, bool fullCtx): Constructs a new instance of the {@link LookaheadEventInfo} class with the specified detailed lookahead information.

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.

decision int decision;: The invoked decision number which this event is related to.
configs ATNConfigSet configs;: The configuration set containing additional information relevant to the prediction state when the current event occurred, or {@code null} if no additional information is relevant or available.
input TokenStream input;: The input token stream which is being parsed.
startIndex size_t startIndex;: Undocumented in source.
stopIndex size_t stopIndex;: Undocumented in source.
fullCtx bool fullCtx;: {@code true} if the current event occurred during LL prediction; otherwise, {@code false} if the input occurred during SLL prediction.
