- Parameters:
refinePattern
- a pattern for detecting which match edges to refine. If the declaring class of the field related to the match edge matches the pattern, the match edge will be refined. For example, the patternPattern.compile("Ljava/util")

shouldRefine
public boolean shouldRefine(IField field, PointerKey basePtr, PointerKey val, IFlowLabel label, StateMachine.State state) - Specified by:
shouldRefine
in interfaceFieldRefinePolicy
- Parameters:
field
- the accessed fieldbasePtr
- 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.
-
nextPass
public boolean nextPass()- Specified by:
nextPass
in interfaceFieldRefinePolicy
- Returns:
true
if more refinement can be done, and hence another pass can be attempted;false
otherwise
-
getHistory
- Returns:
- a String representation of the decisions made by this
