Methods

Modifier and Type	Method and Description
void	choiceGeneratorAdvanced(VM vm, ChoiceGenerator<?> currentCG) the next choice was requested from a previously registered ChoiceGenerator NOTE - this notification happens before the KernelState is stored, i.e.
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	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	stateRestored(Search search) a previously generated state was restored (can be on a completely different path)

Method Detail

stateAdvanced

public void stateAdvanced(Search search)

Description copied from interface: SearchListener

got the next state Note - this will be notified before any potential propertyViolated, in which case the currentError will be already set

Specified by:

stateAdvanced in interface SearchListener

Overrides:

stateAdvanced in class ListenerAdapter

stateBacktracked

public void stateBacktracked(Search search)

Description copied from interface: SearchListener

state was backtracked one step

Specified by:

stateBacktracked in interface SearchListener

Overrides:

stateBacktracked in class ListenerAdapter

stateRestored

public void stateRestored(Search search)

Description copied from interface: SearchListener

a previously generated state was restored (can be on a completely different path)

Specified by:

stateRestored in interface SearchListener

Overrides:

stateRestored in class ListenerAdapter

choiceGeneratorAdvanced

public void choiceGeneratorAdvanced(VM vm,
                           ChoiceGenerator<?> currentCG)

Description copied from interface: VMListener

the next choice was requested from a previously registered ChoiceGenerator NOTE - this notification happens before the KernelState is stored, i.e. listeners are NOT allowed to alter the KernelState (e.g. by changing field values or thread states)

Specified by:

choiceGeneratorAdvanced in interface VMListener

Overrides:

choiceGeneratorAdvanced in class ListenerAdapter

instructionExecuted

public void instructionExecuted(VM vm,
                       ThreadInfo ti,
                       Instruction nextInsn,
                       Instruction executedInsn)

Description copied from interface: VMListener

VM has executed the next instruction (can be used to analyze branches, monitor PUTFIELD / GETFIELD and INVOKExx / RETURN instructions)

Specified by:

instructionExecuted in interface VMListener

Overrides:

instructionExecuted in class ListenerAdapter
