net.morimekta.testing.concurrent.ImmediateScheduledExecutor

All Implemented Interfaces:

Executor, ExecutorService, ScheduledExecutorService, FakeClock.TimeListener

public class ImmediateScheduledExecutor
extends Object
implements ScheduledExecutorService, FakeClock.TimeListener

A scheduled executor that uses a fake clock as back-bone to the executor. To trigger the executions, call FakeClock.tick(long) on the fake clock. The executions will be handled in thread of the tick itself.

Constructor Detail

ImmediateScheduledExecutor

public ImmediateScheduledExecutor(FakeClock clock)

Create a fake scheduled executor.

Parameters:

clock - Clock to trigger executions.

Method Detail

newCurrentTime

public void newCurrentTime(Instant now)

Specified by:

newCurrentTime in interface FakeClock.TimeListener

Parameters:

now - The new current time value.

getDelay

public Duration getDelay(Instant now)

Description copied from interface: FakeClock.TimeListener

Get delay until the next something to be handled. Will return the default max value if nothing else. If something is scheduled to happen immediately, FakeClock.MIN_DELAY should be returned.

Specified by:

getDelay in interface FakeClock.TimeListener

Parameters:

now - The current time when asking.

Returns:

The time to delay. NULL values, Duration.ZERO and negative durations will be ignored.
