Interface LoadSimulator

All Superinterfaces:

Runnable

All Known Implementing Classes:

AbstractLoadSimulator, CpuSimulator, DiskInputSimulator, DiskOutputSimulator, FibonacciCpuSimulator, MemorySimulator, RandomAccessDiskInputSimulator, RandomAccessDiskOutputSimulator

public interface LoadSimulator
extends Runnable

Represents a thread simulating some system load. System load can be CPU, memory, Disk I/O, ...

This type simulates some system load when started as a thread. Further, it defines methods for getting and setting as well as increasing and decreasing some load parameter. Implementing classes should use the load parameter, set by those methods, for their simulation logic.

Class AbstractLoadSimulator provides a skeleton implementation of a LoadSimulator. Subclassing AbstractLoadSimulator is the preferred way for clients to create new LoadSimulator classes, as it already provides common simulation behavior as well as synchronization mechanisms.

Method Detail

run

void run()

Executes the simulation logic. This method should be used to implement the simulator's main simulation logic, i.e. the actual system load (CPU, memory, etc.) for which this LoadSimulator is responsible should be simulated.

From Runnable.run():

Specified by:

run in interface Runnable

getLoad

long getLoad()

Returns:

returns the load to be simulated

setLoad

void setLoad(long desiredLoad)

Sets the load to be simulated.

Parameters:

desiredLoad - the load to be simulated

increaseLoad

void increaseLoad(long delta)

Increases the load of the simulator by delta.

Parameters:

delta - the amount by which the load will be increased

decreaseLoad

void decreaseLoad(long delta)

Decreases the load of the simulator by delta.

Parameters:

delta - the amount by which the load will be decreased

getMaximumLoad

long getMaximumLoad()

isMaximumLoad

boolean isMaximumLoad()

isZeroLoad

boolean isZeroLoad()
