Interface Simulator.Probe

All Known Implementing Classes:

BranchCounter, Counter, MulticastProbe, ProgramProfiler, SequenceProbe, Simulator.InstructionCountTimeout, StackMonitor.Monitor

Enclosing interface:

Simulator

public static interface Simulator.Probe

The Simulator.Probe interface represents a programmer-defined probe that can be inserted at a particular instruction in the program. or at every instruction. Probes can be usedfor profiling, analysis, or program understanding. The fireBefore() and fireAfter() methods are called before and after the target instruction executes in simulation. Probes can also be inserted in the "main loop" of the interpreter, so that the probe fires before and after every instruction executed.

Method Summary

void	fireAfter(Instr i, int address, State state) The fireAfter() method is called after the probed instruction executes.
void	fireBefore(Instr i, int address, State state) The fireBefore() method is called before the probed instruction executes.

Method Detail

fireBefore

public void fireBefore(Instr i,
                       int address,
                       State state)

The fireBefore() method is called before the probed instruction executes.

Parameters:

i - the instruction being probed

address - the address at which this instruction resides

state - the state of the simulation

fireAfter

public void fireAfter(Instr i,
                      int address,
                      State state)

The fireAfter() method is called after the probed instruction executes.

Parameters:

i - the instruction being probed

address - the address at which this instruction resides

state - the state of the simulation
