All Implemented Interfaces:

Analysis<CFValue,LockStore,LockTransfer>, ForwardAnalysis<CFValue,LockStore,LockTransfer>

public class LockAnalysis
extends CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

The analysis class for the lock type system.

This class extends CFAbstractAnalysis so that LockStore is used rather than CFStore.

Constructor Details

LockAnalysis

public LockAnalysis(BaseTypeChecker checker,
 LockAnnotatedTypeFactory factory)

Creates a new LockAnalysis.

Parameters:

checker - the checker

factory - the factory

Method Details

createTransferFunction

public LockTransfer createTransferFunction()

Description copied from class: CFAbstractAnalysis

Returns the transfer function to be used by the analysis.

Overrides:

createTransferFunction in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

Returns:

the transfer function to be used by the analysis

createEmptyStore

public LockStore createEmptyStore(boolean sequentialSemantics)

Description copied from class: CFAbstractAnalysis

Returns an empty store of the appropriate type.

Specified by:

createEmptyStore in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

Returns:

an empty store of the appropriate type

createCopiedStore

public LockStore createCopiedStore(LockStore s)

Description copied from class: CFAbstractAnalysis

Returns an identical copy of the store s.

Specified by:

createCopiedStore in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

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,LockStore,LockTransfer>

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
