Constructor Details

InitializationAnalysis

protected InitializationAnalysis(BaseTypeChecker checker,
 InitializationParentAnnotatedTypeFactory factory)

Creates a new InitializationAnalysis.

Parameters:

checker - the checker

factory - the factory

Method Details

createEmptyStore

public InitializationStore createEmptyStore(boolean sequentialSemantics)

Description copied from class: CFAbstractAnalysis

Returns an empty store of the appropriate type.

Specified by:

createEmptyStore in class CFAbstractAnalysis<CFValue,InitializationStore,InitializationTransfer>

Returns:

an empty store of the appropriate type

createCopiedStore

public InitializationStore createCopiedStore(InitializationStore s)

Description copied from class: CFAbstractAnalysis

Returns an identical copy of the store s.

Specified by:

createCopiedStore in class CFAbstractAnalysis<CFValue,InitializationStore,InitializationTransfer>

Returns:

an identical copy of the store s

createAbstractValue

public @Nullable 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,InitializationStore,InitializationTransfer>

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

getTypeFactory

public InitializationParentAnnotatedTypeFactory getTypeFactory()

Overrides:

getTypeFactory in class CFAbstractAnalysis<CFValue,InitializationStore,InitializationTransfer>
