Constructors

PredicateEvalInfo(int decision, TokenStream input, int startIndex, int stopIndex, SemanticContext semctx, bool evalResult, int predictedAlt, bool fullCtx)
Constructs a new instance of the PredicateEvalInfo class with the specified detailed predicate evaluation 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
evalResult → bool
The result of evaluating the semantic context {@link #semctx}.
final
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 number for the decision which is guarded by the semantic context {@link #semctx}. Note that other ATN configurations may predict the same alternative which are guarded by other semantic contexts and/or {@link SemanticContext#NONE}.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semctx → SemanticContext
The semantic context which was evaluated.
final
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.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
