Method Detail

nextPass

public boolean nextPass()

Specified by:

nextPass in interface FieldRefinePolicy

Returns:

true if more refinement can be done, and hence another pass can be attempted; false otherwise

shouldRefine

public boolean shouldRefine(IField field,
                            PointerKey basePtr,
                            PointerKey val,
                            IFlowLabel label,
                            StateMachine.State state)

Specified by:

shouldRefine in interface FieldRefinePolicy

Parameters:

field - the accessed field

basePtr - the base pointer of the access

Returns:

true if match edges for the field access should be refined. Otherwise, false is returned, indicating that the field can be handled with match edges.
