Variables

parents
PredictionContext[] parents;

Parent can be null only if full ctx mode and we make an array from {@link #EMPTY} and non-empty. We merge {@link #EMPTY} by using null parent and returnState == {@link #EMPTY_RETURN_STATE}.

returnStates
int[] returnStates;

Sorted for merge, no duplicates; if present, {@link #EMPTY_RETURN_STATE} is always last. @uml @final

Inherited Members

From PredictionContext

EMPTY
EmptyPredictionContext EMPTY;

Represents {@code $} in local context prediction, which means wildcard. {@code *+x = *}.

EMPTY_RETURN_STATE
int EMPTY_RETURN_STATE;

Represents {@code $} in an array in full context mode, when {@code $} doesn't mean wildcard: {@code $ + x = [$,x]}. Here, {@code $} = {@link #EMPTY_RETURN_STATE}.

globalNodeCount
int globalNodeCount;

mergeSingletons
PredictionContext mergeSingletons(SingletonPredictionContext a, SingletonPredictionContext b, bool rootIsWildcard, DoubleKeyMap!(PredictionContext, PredictionContext, PredictionContext) mergeCache)

@uml Merge two {@link SingletonPredictionContext} instances.

mergeRoot
PredictionContext mergeRoot(SingletonPredictionContext a, SingletonPredictionContext b, bool rootIsWildcard)

Handle case where at least one of {@code a} or {@code b} is {@link #EMPTY}. In the following diagrams, the symbol {@code $} is used to represent {@link #EMPTY}.

mergeArrays
PredictionContext mergeArrays(ArrayPredictionContext a, ArrayPredictionContext b, bool rootIsWildcard, DoubleKeyMap!(PredictionContext, PredictionContext, PredictionContext) mergeCache)

Merge two {@link ArrayPredictionContext} instances. * <p>Different tops, different parents.<br> <embed src="images/ArrayMerge_DiffTopDiffPar.svg" type="image/svg+xml"/></p>

combineCommonParents
void combineCommonParents(PredictionContext[] parents)

Make pass over all <em>M</em> {@code parents}; merge any {@code equals()} ones.
