Method Detail

until

public static void until(Callable<Boolean> condition)

Blocks until the given condition evaluates to true. The condition is evaluated every 50 milliseconds, so, the given condition should be an idempotent operation. If the condition is not met within 10 seconds, an exception is thrown.

Parameters:

condition - the condition to wait for

until

public static void until(Callable<Boolean> condition,
                         long timeout,
                         TimeUnit timeUnit)

Blocks until the given condition evaluates to true. The condition is evaluated every 50 milliseconds, so, the given condition should be an idempotent operation. If the condition is not met within the given timeout, an exception is thrown.

Parameters:

condition - the condition to wait for

timeout - the timeout value

timeUnit - the unit for the timeout

until

public static void until(Callable<Boolean> condition,
                         long timeout,
                         TimeUnit timeUnit,
                         long frequency)

Blocks until the given condition evaluates to true. The condition is evaluated every @code{frequency} milliseconds, so, the given condition should be an idempotent operation. If the condition is not met within the given timeout, an exception is thrown.

Parameters:

condition - the condition to wait for

timeout - the timeout value

timeUnit - the unit for the timeout

frequency - the frequency of the condition's evaluation in milliseconds

forPortToBeUsed

public static void forPortToBeUsed(int port)

Waits for a given port to become used.

Parameters:

port -

forPortToBeFree

public static void forPortToBeFree(int port)

Waits for a given port to be free

Parameters:

port -
