Method Detail

sleep

public static boolean sleep(long duration,
                            Supplier<Boolean> cancelCondition,
                            Class<?> invokingClass)

sleep

public static boolean sleep(long duration,
                            Supplier<Boolean> cancelCondition,
                            long checkIntervalMs,
                            String invocationContext)

Sleeps for a maximum of duration milliseconds, checking every checkIntervalMs milliseconds whether the cancelCondition is met, and cancelling the sleeping if so.

Parameters:

duration - number of milliseconds to sleep

cancelCondition - method which is invoked to verify if execution is to be cancelled. This method is invoked often, and in time-sensitive code, so it should return quickly.

checkIntervalMs - number of milliseconds between cancellation checks. A lower limit of 10 ms is enforced, but higher values (say, >= 100 ms) are strongly recommended.

invocationContext - indication of the context where the method invocation originated. Only used for logging, and may be null.

Returns:

true if the entire sleep went through without being cancelled, false if it was cancelled.
