Detailed Description

How long a play action waits for a receiver the user selected that is not in the registry right now.

After a suspend the registry may have dropped the renderer (no ssdp:alive could be received) and it is back a moment after a new search, so giving up at once would refuse the play and, worse, drop the receiver from the stored selection.

At most MAX_ATTEMPTS looks in total, WAIT_MILLIS apart (about 5 s), with a chance to start a search before each wait. No Android classes: unit-testable on the JVM. Meant for a worker thread only: await sleeps.

Member Function Documentation

await()

int de.yaacc.upnp.ReceiverAvailabilityPolicy.await	(	IntSupplier	missingCount,
		IntConsumer	beforeWaiting )

Looks until no selected receiver is missing, the looks are used up or the thread is interrupted while waiting.

Parameters

missingCount	how many selected receivers are not in the registry now
beforeWaiting	called with the number of the look that found receivers missing, right before the wait (start a search here); not called after the last look
