Method Summary

Modifier and Type	Method and Description
void	instructionExecuted(VM vm, ThreadInfo ti, Instruction nextInsn, Instruction executedInsn) VM has executed the next instruction (can be used to analyze branches, monitor PUTFIELD / GETFIELD and INVOKExx / RETURN instructions)
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	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	threadStarted(VM vm, ThreadInfo ti) new Thread entered run() method
