Method Detail

getProcedureCall

ProcedureCall getProcedureCall(Method method,
                               HeapConfiguration initialHeap)

Wraps the method and initialHeap in a new procedureCall

Parameters:

method - the code of the procedure

initialHeap - the initialHeap from which the procedureCall should start

Returns:

the corresponding procedureCall

registerProcedure

void registerProcedure(ProcedureCall call)

Enqueues the procedureCall to be analyzed later on. Semantics should call this method whenever it finds for recursive method a initialHeap without an existing contract. (non-recursive methods can instead directly be executed to obtain the contract)

Parameters:

call - the required procedureCall

registerDependency

void registerDependency(ProgramState callingState,
                        ProcedureCall call)

Stores a dependency between the given state and procedureCall. Semantics should call this method whenever it finds a methodCall (even when it already has a contract or when the method is non-recursive. The reason is, that the contract could still change during the fixpoint computation and then the given state also needs to be continued)

Parameters:

callingState - the state when the call is invoked

call - the corresponding procedureCall

registerStateSpace

void registerStateSpace(ProcedureCall call,
                        StateSpace generatedStateSpace)

Stores the relation between a proceduceCall and the stateSpace generated by this procedureCall. This method should be called when a procedureCall is evaluated. It is necessary to continue stateSpaces when new contracts are discovered.

Parameters:

call - the call corresponding to the stateSpace

generatedStateSpace - the stateSpace corresponding to the call
