Constructor Details

OptionalImplTransfer

public OptionalImplTransfer(CFAbstractAnalysis<CFValue,CFStore,CFTransfer> analysis)

Create an OptionalImplTransfer.

Parameters:

analysis - the OptionalImpl Checker instance

Method Details

initialStore

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

Description copied from class: CFAbstractTransfer

The initial store maps method formal parameters to their currently most refined type.

Specified by:

initialStore in interface ForwardTransferFunction<CFValue,CFStore>

Overrides:

initialStore in class CFAbstractTransfer<CFValue,CFStore,CFTransfer>

Parameters:

underlyingAST - an abstract syntax tree

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

Returns:

the initial store

visitMethodInvocation

public TransferResult<CFValue,CFStore> visitMethodInvocation(MethodInvocationNode n,
 TransferInput<CFValue,CFStore> in)

Specified by:

visitMethodInvocation in interface NodeVisitor<TransferResult<CFValue,CFStore>,TransferInput<CFValue,CFStore>>

Overrides:

visitMethodInvocation in class CFAbstractTransfer<CFValue,CFStore,CFTransfer>
