Class RunOnce

java.lang.Object

ur_rna.Utilities.RunOnce

All Implemented Interfaces:

java.lang.Runnable, RunnableOnce

public class RunOnce
extends java.lang.Object
implements RunnableOnce

This class operates as a proxy for a Runnable. When run() is called initially, it is delegated to Runnable.run(), and subsequent calls to run() are be ignored (i.e. they do not result in a call to Runnable.run()). The method hasRun() can be used to determine whether or not run() has been called. The reset() method can be called to re-enable run() to make another one-time call to Runnable.run()).

Method Summary

Modifier and Type	Method and Description
boolean	hasRun() Indicates whether run() has been called.
void	mockRun() Fakes a call to run.
void	reset() Resets the internal state of the RunnableOnce instance, so run() can be called again, even if it has already been called once.
void	run() When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.

Method Detail

hasRun

public boolean hasRun()

Indicates whether run() has been called.

Specified by:

hasRun in interface RunnableOnce

Returns:

True if run() has already been called. This can be reset by a call to reset().

mockRun

public void mockRun()

Fakes a call to run. After calling this, hasRun() will return true, but run() is never actually called.

reset

public void reset()

Resets the internal state of the RunnableOnce instance, so run() can be called again, even if it has already been called once.

Specified by:

reset in interface RunnableOnce

run

public void run()

When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.

The general contract of the method run is that it may take any action whatsoever.

Specified by:

run in interface java.lang.Runnable
