Description copied from class: CFAbstractAnalysis

Returns an empty store of the appropriate type.

Specified by:

createEmptyStore in class CFAbstractAnalysis<KeyForValue,KeyForStore,KeyForTransfer>

Returns:

an empty store of the appropriate type

createCopiedStore

public KeyForStore createCopiedStore(KeyForStore store)

Description copied from class: CFAbstractAnalysis

Returns an identical copy of the store s.

Specified by:

createCopiedStore in class CFAbstractAnalysis<KeyForValue,KeyForStore,KeyForTransfer>

Returns:

an identical copy of the store s

createAbstractValue

public KeyForValue createAbstractValue(Set<AnnotationMirror> annotations,
