Constructor Detail

ReturnValueStmt

public ReturnValueStmt(SceneObject sceneObject,
                       Value returnValue,
                       Type type)

Method Detail

computeSuccessors

public Collection<ProgramState> computeSuccessors(ProgramState programState)

Description copied from interface: SemanticsCommand

Executes a single step of the abstract program semantics on the given program state. Since the abstract program semantics may be non-deterministic (for example if a conditional statement cannot be evaluated), this results in a set of successor program states in general.

Parameters:

programState - The state on which the abstract program semantics shall be executed.

Returns:

All states resulting from executing the program semantics on programState.

needsMaterialization

public boolean needsMaterialization(ProgramState programState)

toString

public String toString()

Overrides:

toString in class Object

getPotentialViolationPoints

public ViolationPoints getPotentialViolationPoints()

Returns:

All potential violation points that may prevent execution of this statement.

getSuccessorPCs

public Set<Integer> getSuccessorPCs()

Returns:

The set of all program locations that are direct successors of this program statement in the underlying control flow graph.

needsCanonicalization

public boolean needsCanonicalization()

Returns:

true, if the statement always requires canonicalization
