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

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;: @uml @shared
id int id;: Undocumented in source.
fromRuleContext PredictionContext fromRuleContext(ATN atn, RuleContext outerContext): Undocumented in source. Be warned that the author may not have intended to support it.
size size_t size(): Undocumented in source.
getParent PredictionContext getParent(int index): Undocumented in source.
getReturnState int getReturnState(int index): Undocumented in source.
isEmpty bool isEmpty(): @uml This means only the {@link #EMPTY} context is in set.

toHash size_t toHash(): @uml @safe @nothrow @override
opEquals bool opEquals(Object obj): @uml @override

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. * Different tops, different parents. <embed src="images/ArrayMerge_DiffTopDiffPar.svg" type="image/svg+xml"/>
combineCommonParents void combineCommonParents(PredictionContext[] parents): Make pass over all M {@code parents}; merge any {@code equals()} ones.
toDOTString string toDOTString(PredictionContext context): Undocumented in source. Be warned that the author may not have intended to support it.
getCachedContext PredictionContext getCachedContext(PredictionContext context, PredictionContextCache contextCache, PredictionContext[PredictionContext] visited): ref visited ?
