Method Detail

reset

public void reset()

Description copied from interface: Pauser

Resets the pauser's internal state back (if any) to the most aggressive setting.

Pausers that progressively increases the pause time are reset back to its lowest pause time.

Call this if you just did some work.

Specified by:

reset in interface Pauser

pause

public void pause()

Deprecated.

Description copied from interface: Pauser

Pauses the current thread.

The actual pause time and thread scheduling impact is not specified and depends on the implementing class. For some implementations, a progressive increase of the pause time is employed, thread executions may or may not be yielded, whereas other implementations may not pause or yield at all.

Thus, depending on the implementation this could do nothing (busy spin), yield, sleep, ...

Call this if no work was done.

Specified by:

pause in interface Pauser

protected void doPause(long maxPauseNS)

Deprecated.
