IMPLEMENTATION NOTES:
Offer is allowed from a SINGLE thread.
Offer allocates a new node (holding the offered value) and:
e
- not null
, will throw NPE if it isMessagePassingQueue.offer(Object)
,
Queue.offer(java.lang.Object)
public int fill(MessagePassingQueue.Supplier<E> s)
MessagePassingQueue
while(relaxedOffer(s.get());There's no strong commitment to the queue being full at the end of a fill. Called from a producer thread subject to the restrictions appropriate to the implementation.
Unbounded queues will fill up the queue with a fixed amount rather than fill up to oblivion.
WARNING: Explicit assumptions are made with regards to MessagePassingQueue.Supplier.get()
make sure you have read
and understood these before using this method.

thread subject to the restrictions appropriate to the implementation.

Called from a producer thread subject to the restrictions appropriate to the implementation. The main difference
being that implementors MUST assure room in the queue is available BEFORE calling MessagePassingQueue.Supplier.get()
.
