Class LockAnalysis

java.lang.Object

org.checkerframework.dataflow.analysis.Analysis<V,S,T>

org.checkerframework.framework.flow.CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

org.checkerframework.checker.lock.LockAnalysis

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.

Method Detail

createTransferFunction

public LockTransfer createTransferFunction()

Overrides:

createTransferFunction in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

Returns:

the transfer function to be used by the analysis

createEmptyStore

public LockStore createEmptyStore(boolean sequentialSemantics)

Specified by:

createEmptyStore in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

Returns:

an empty store of the appropriate type

createCopiedStore

public LockStore createCopiedStore(LockStore s)

Specified by:

createCopiedStore in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

Returns:

an identical copy of the store s.

createAbstractValue

public CFValue createAbstractValue(java.util.Set<javax.lang.model.element.AnnotationMirror> annotations,
                                   javax.lang.model.type.TypeMirror underlyingType)

Specified by:

createAbstractValue in class CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

Returns:

an abstract value containing the given annotations and underlyingType.
