Method Detail

getTime

Timepoint getTime()

Returns the current time based on this timestamp provider as a Timepoint.

Returns:

getTime

Timepoint getTime(long sinceEpoch,
                TimeUnit unit)

Returns the given time as a Timepoint based off of this timestamp provider

Parameters:

sinceEpoch -

unit -

Returns:

getUnit

TimeUnit getUnit()

Return the units of getTime(). This method's return value must be constant over at least the life of the object implementing this interface.

Returns:

this instance's time unit

sleepPast

Timepoint sleepPast(Timepoint futureTime)
                    throws InterruptedException

Block until the current time as returned by getTime() is greater than the given timepoint.

Parameters:

futureTime - The time to sleep past

Returns:

the current time in the same units as the unit argument

Throws:

InterruptedException - if externally interrupted

sleepFor

void sleepFor(Duration duration)
              throws InterruptedException

Sleep for the given duration of time.

Parameters:

duration -
