Class StackMonitor.Monitor

java.lang.Object
  avrora.monitors.StackMonitor.Monitor

All Implemented Interfaces:

Monitor, Simulator.Probe

Enclosing class:

StackMonitor

public class StackMonitor.Monitor

extends java.lang.Object

implements Monitor, Simulator.Probe

The Monitor class implements a monitor for the stack height that inserts a probe after every instruction in the program and checks the stack height after each instruction is executed.

Method Summary

void	fireAfter(Instr i, int address, State s) The fireAfter() method is called after the probed instruction executes.
void	fireBefore(Instr i, int address, State s) The fireBefore() method is called before the probed instruction executes.
void	report() The report() method generates a textual report after the simulation is complete.

Method Detail

fireBefore

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

Description copied from interface: Simulator.Probe

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

Specified by:

fireBefore in interface Simulator.Probe

Parameters:

i - the instruction being probed

address - the address at which this instruction resides

s - the state of the simulation

fireAfter

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

Description copied from interface: Simulator.Probe

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

Specified by:

fireAfter in interface Simulator.Probe

Parameters:

i - the instruction being probed

address - the address at which this instruction resides

s - the state of the simulation

report

public void report()

The report() method generates a textual report after the simulation is complete. The text report contains the 3 smallest stack pointers encountered (tracking all three is necessary because the stack pointer begins at 0 and then is initialized one byte at a time).

Specified by:

report in interface Monitor
