opsPerSecAtDelta

public float opsPerSecAtDelta(long opCount,
                              long delta)

Parameters:

keyCount -

Returns:

opsPerSecAtMark

public float opsPerSecAtMark(long opCount)

deltaAtMark

public long deltaAtMark()

Returns:

the elapsed time since call to mark() in the timer's TimeUnit

deltaAtMark

public long deltaAtMark(java.util.concurrent.TimeUnit unit)

Parameters:

unit -

Returns:

the elapsed time since call to mark() in the specified unit. If the unit provided is finer than the timer's internal time unit, finer precision will naturally be irrelevant.
