Class AbstractLoadSimulator

java.lang.Object

com.martensigwart.fakeload.AbstractLoadSimulator

All Implemented Interfaces:

LoadSimulator, Runnable

Direct Known Subclasses:

CpuSimulator, DiskInputSimulator, DiskOutputSimulator, MemorySimulator

public abstract class AbstractLoadSimulator
extends Object
implements LoadSimulator

Skeleton LoadSimulator implementation.

Load is simulated by running a while loop inside the run() method. In the loop the executing thread waits when there is nothing to do as indicated by waitConditionFulfilled() method. When there is something to simulate, load gets simulated via the simulateLoad(long) method which has to be implemented by subclasses.

Note: When calling the constructor of this class from a subclass, passing a value smaller or equal zero as maximumLoad will cause the max value to be Long.MAX_VALUE

Since:

1.8

Method Detail

run

public void run()

Description copied from interface: LoadSimulator

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 LoadSimulator

Specified by:

run in interface Runnable

getLoad

public long getLoad()

Specified by:

getLoad in interface LoadSimulator

Returns:

returns the load to be simulated

setLoad

public void setLoad(long desiredLoad)

Description copied from interface: LoadSimulator

Sets the load to be simulated.

Specified by:

setLoad in interface LoadSimulator

Parameters:

desiredLoad - the load to be simulated

increaseLoad

public void increaseLoad(long delta)

Description copied from interface: LoadSimulator

Increases the load of the simulator by delta.

Specified by:

increaseLoad in interface LoadSimulator

Parameters:

delta - the amount by which the load will be increased

decreaseLoad

public void decreaseLoad(long delta)

Description copied from interface: LoadSimulator

Decreases the load of the simulator by delta.

Specified by:

decreaseLoad in interface LoadSimulator

Parameters:

delta - the amount by which the load will be decreased

getMaximumLoad

public long getMaximumLoad()

Specified by:

getMaximumLoad in interface LoadSimulator

isMaximumLoad

public boolean isMaximumLoad()

Specified by:

isMaximumLoad in interface LoadSimulator

isZeroLoad

public boolean isZeroLoad()

Specified by:

isZeroLoad in interface LoadSimulator
