Method Detail

isJobSchedulable

public boolean isJobSchedulable()

Description copied from interface: InternalClock

The clock is capable to execute code when a certain time is reached and before the time advances further.

Specified by:

isJobSchedulable in interface InternalClock

createJob

public InternalClock.TimeReachedJob createJob(InternalClock.TimeReachedEvent ev)

Description copied from interface: InternalClock

Creates a job object for the specified event callback.

Specified by:

createJob in interface InternalClock

schedule

public void schedule(InternalClock.TimeReachedJob j,
                     long _millis)

Description copied from interface: InternalClock

Schedules or reschedules the timer event job to be run at the specified point in time.

Specified by:

schedule in interface InternalClock

disableJob

public void disableJob(InternalClock.TimeReachedJob j)

Description copied from interface: InternalClock

Disable the job clearing used resources.

Specified by:

disableJob in interface InternalClock

millis

public long millis()

Description copied from interface: InternalClock

Returns the milliseconds since epoch. When using a simulated clock either this method or InternalClock.sleep(long) needs to be called to make time pass by and make this method return an increased number.

Specified by:

millis in interface InternalClock

sleep

public void sleep(long _millis)
           throws InterruptedException

Description copied from interface: InternalClock

Wait for the specified amount of time in milliseconds. The value of 0 means that the thread may sleep some tiny amount of time or not at all.

When using a simulated clock either this method or InternalClock.millis() needs to be called to make time pass and make InternalClock.millis() return an increased number.

Specified by:

sleep in interface InternalClock

Throws:

InterruptedException
