Constructors

LookaheadEventInfo(int decision, ATNConfigSet? configs, int predictedAlt, TokenStream input, int startIndex, int stopIndex, bool fullCtx)
Constructs a new instance of the LookaheadEventInfo class with the specified detailed lookahead information.

Properties

configs → ATNConfigSet?
The configuration set containing additional information relevant to the prediction state when the current event occurred, or null if no additional information is relevant or available.
finalinherited
decision → int
The invoked decision number which this event is related to.
finalinherited
fullCtx → bool
true if the current event occurred during LL prediction; otherwise, false if the input occurred during SLL prediction.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
input → TokenStream
The input token stream which is being parsed.
finalinherited
predictedAlt ↔ int
The alternative chosen by adaptivePredict(), not necessarily 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.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
startIndex → int
The token index in the input stream at which the current prediction was originally invoked.
finalinherited
stopIndex → int
The token index in the input stream at which the current event occurred.
finalinherited

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
