Method Summary

Modifier and Type	Method and Description
void	propertyViolated(Search search) JPF encountered a property violation.
void	searchConstraintHit(Search search) there was some contraint hit in the search, we back out could have been turned into a property, but usually is an attribute of the search, not the application
void	searchFinished(Search search) we're done, either with or without a preceeding error
void	searchStarted(Search search) we get this after we enter the search loop, but BEFORE the first forward
void	stateAdvanced(Search search) got the next state Note - this will be notified before any potential propertyViolated, in which case the currentError will be already set
void	stateBacktracked(Search search) state was backtracked one step
void	stateProcessed(Search search) state is fully explored
void	stateRestored(Search search) a previously generated state was restored (can be on a completely different path)
