Method Detail

whileTrue

public static void whileTrue(ICondition condition,
                             long millis)

Runs an empty loop until either the contidion is false or the specified time in milliseconds is over (more or less). That particularly makes sense if the condition gets influenced by a different thread. Therefore this thread sleeps one millisecond per loop iteration to allow other threads to do something.

Parameters:

condition - A condition that is used to continue (true) or finish (false) the loop

millis - The time in milliseconds after which the loop gets terminated independent of the condition

whileFalse

public static void whileFalse(ICondition condition,
                              long millis)

Runs an empty loop until either the contidion is true or the specified time in milliseconds is over. That particularly makes sense if the condition gets influenced by a different thread. Therefore this thread sleeps one millisecond per loop iteration to allow other threads to do something.

Parameters:

condition - A condition that is used to continue (false) or finish (true) the loop

millis - The time in milliseconds after which the loop gets terminated independent of the condition
