      edu.memphis.ccrg.lida.framework.tasks.TaskSpawnerImpl
          edu.memphis.ccrg.lida.framework.tasks.RandomizingTaskSpawner

All Implemented Interfaces:

Initializable, TaskSpawner

public class RandomizingTaskSpawner
extends TaskSpawnerImpl

A TaskSpawner which randomizes the execution of tasks. For each execution, a task's nextTicksPerRun is randomized using a uniform distribution.
To modify this distribution override the method randomizeTicksPerRun(long).

Constructor Summary

RandomizingTaskSpawner()

Method Summary

void	addTask(FrameworkTask task) First randomizes task's ticksPerRun and then adds and runs it.
double	getVariation() Gets variation
void	init() Sets the following parameter: variation type=double the amount of possible variation in a randomized value of ticksPerRun from its initial value
long	randomizeTicksPerRun(long ticksPerRun) Randomizes ticksPerRun by variation percent.
void	receiveFinishedTask(FrameworkTask task) First randomizes task's ticksPerRun and then adds and runs it then calls TaskSpawnerImpl.receiveFinishedTask(FrameworkTask).
void	setVariation(double v) Sets variation

Constructor Detail

RandomizingTaskSpawner

public RandomizingTaskSpawner()

Method Detail

init

public void init()

Sets the following parameter: variation type=double the amount of possible variation in a randomized value of ticksPerRun from its initial value

Specified by:

init in interface Initializable

Overrides:

init in class InitializableImpl

getVariation

public double getVariation()

Gets variation

Returns:

the variation

setVariation

public void setVariation(double v)

Sets variation

Parameters:

v - the variation to set

randomizeTicksPerRun

public long randomizeTicksPerRun(long ticksPerRun)

Randomizes ticksPerRun by variation percent. Uses uniform distribution for random value.

Parameters:

ticksPerRun - parameter to randomize

Returns:

new non-zero ticksPerRun value

addTask

public void addTask(FrameworkTask task)

First randomizes task's ticksPerRun and then adds and runs it.

Specified by:

addTask in interface TaskSpawner

Overrides:

addTask in class TaskSpawnerImpl

Parameters:

task - the task to add.

receiveFinishedTask

public void receiveFinishedTask(FrameworkTask task)

First randomizes task's ticksPerRun and then adds and runs it then calls TaskSpawnerImpl.receiveFinishedTask(FrameworkTask).

Specified by:

receiveFinishedTask in interface TaskSpawner

Overrides:

receiveFinishedTask in class TaskSpawnerImpl

Parameters:

task - finished FrameworkTask
