ArrayElementsTypeFlow(AnalysisObject sourceObject)

Method Summary

Modifier and Type	Method and Description
boolean	canSaturate() Can this type flow saturate? By default all type flows can saturate, with the exception of a few ones that need to track all their types, e.g., AllInstantiated, AllSynchronized, etc.
TypeFlow<AnalysisType>	copy(PointsToAnalysis bb, MethodFlowsGraph methodFlows) By default a type flow is not cloneable.
TypeState	filter(PointsToAnalysis bb, TypeState update)
AnalysisObject	object()
protected void	onInputSaturated(PointsToAnalysis bb, TypeFlow<?> input) Notified by an input that it is saturated and it will stop sending updates.
String	toString()
