  - 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)
```
    returns true if A.shouldRefine(field) || B.shouldRefine(field). Note that if A.shouldRefine(field) is true, B.shouldRefine(field) is not called.
    
    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.
