Constructor Details

LockTransfer

public LockTransfer(LockAnalysis analysis,
 LockChecker checker)

Create a transfer function for the Lock Checker.

Parameters:

analysis - the analysis this transfer function belongs to

checker - the type-checker this transfer function belongs to

Method Details

makeLockHeld

protected void makeLockHeld(LockStore store,
 Node node)

Sets a given Node to @LockHeld in the given store.

Parameters:

store - the store to update

node - the node that should be @LockHeld

makeLockPossiblyHeld

protected void makeLockPossiblyHeld(LockStore store,
 Node node)

Sets a given Node to @LockPossiblyHeld in the given store.

Parameters:

store - the store to update

node - the node that should be @LockPossiblyHeld

makeLockHeld

protected void makeLockHeld(TransferResult<CFValue,LockStore> result,
 Node node)

Sets a given Node node to LockHeld in the given TransferResult.

makeLockPossiblyHeld

protected void makeLockPossiblyHeld(TransferResult<CFValue,LockStore> result,
 Node node)

Sets a given Node node to LockPossiblyHeld in the given TransferResult.

initialStore

public LockStore initialStore(UnderlyingAST underlyingAST,
 List<LocalVariableNode> parameters)

Description copied from class: CFAbstractTransfer

Specified by:

initialStore in interface ForwardTransferFunction<CFValue,LockStore>

Overrides:

initialStore in class CFAbstractTransfer<CFValue,LockStore,LockTransfer>

Parameters:

underlyingAST - an abstract syntax tree

parameters - a list of local variable nodes representing formal parameters (if any)

Returns:

the initial store

visitSynchronized

public TransferResult<CFValue,LockStore> visitSynchronized(SynchronizedNode n,
 TransferInput<CFValue,LockStore> p)

Specified by:

visitSynchronized in interface NodeVisitor<TransferResult<CFValue,LockStore>,TransferInput<CFValue,LockStore>>

Overrides:

visitSynchronized in class AbstractNodeVisitor<TransferResult<CFValue,LockStore>,TransferInput<CFValue,LockStore>>
