All Implemented Interfaces:

ExperimentHandle

Direct Known Subclasses:

Experiment

public abstract class AbstractExperimentHandle
extends java.lang.Object
implements ExperimentHandle

Abstract implementation of ExperimentHandle. Classes implementing this abstract class should count down the experimentRunningLatch, getResult() waits on this latch.

Field Summary

protected java.lang.Exception	exception Exception that was raised during execution of the experiment.
protected java.util.concurrent.CountDownLatch	experimentRunningLatch Latch where thread can wait for results of the experiment.
protected ExperimentResult	result Result of this experiment, it is set from the user code setResult()
protected Flag<ExperimentExecutionState>	stateFlag Flag with a state of execution.

Constructor Summary

AbstractExperimentHandle()
Creates a new instance of AbstractHandle

Method Summary

java.lang.Exception	getException() Blocking method returning exception that may have been raised during execution of the experiment.
Flag<ExperimentExecutionState>	getExperimentExecutionFlag()
ExperimentResult	getResult() Returns result of the experiment, blocks if called during execution of the experiment.
