Constructor Details

CFAnalysis

public CFAnalysis(BaseTypeChecker checker,
 GenericAnnotatedTypeFactory<CFValue,CFStore,CFTransfer,CFAnalysis> factory)

Creates a new CFAnalysis.

Parameters:

checker - the checker

factory - the factory

Method Details

createEmptyStore

public CFStore createEmptyStore(boolean sequentialSemantics)

Description copied from class: CFAbstractAnalysis

Returns an empty store of the appropriate type.

Specified by:

createEmptyStore in class CFAbstractAnalysis<CFValue,CFStore,CFTransfer>

Returns:

an empty store of the appropriate type

createCopiedStore

public CFStore createCopiedStore(CFStore s)

Description copied from class: CFAbstractAnalysis

Returns an identical copy of the store s.

Specified by:

createCopiedStore in class CFAbstractAnalysis<CFValue,CFStore,CFTransfer>

Returns:

an identical copy of the store s

createAbstractValue

public CFValue createAbstractValue(AnnotationMirrorSet annotations,
 TypeMirror underlyingType)

Description copied from class: CFAbstractAnalysis

Returns an abstract value containing the given annotations and underlyingType. Returns null if the annotation set has missing annotations.

Specified by:

createAbstractValue in class CFAbstractAnalysis<CFValue,CFStore,CFTransfer>

Parameters:

annotations - the annotations for the result annotated type

underlyingType - the unannotated type for the result annotated type

Returns:

an abstract value containing the given annotations and underlyingType
