public class SpscUnboundedAtomicArrayQueue<E> extends BaseSpscLinkedAtomicArrayQueue<E>
NOTE: This class was automatically generated by org.jctools.queues.atomic.JavaParsingAtomicLinkedQueueGenerator which can found in the jctools-build module. The original source file is SpscUnboundedArrayQueue.java. An SPSC array queue which starts at initialCapacity and grows indefinitely in linked chunks of the initial size. The queue grows only when the current chunk is full and elements are not copied on resize, instead a link to the new chunk is stored in the old chunk for the consumer to follow.

offerColdPath
final boolean offerColdPath(java.util.concurrent.atomic.AtomicReferenceArray<E> buffer, long mask, long pIndex, int offset, E v, MessagePassingQueue.Supplier<? extends E> s)

fill
public int fill(MessagePassingQueue.Supplier<E> s)
Description copied from interface:MessagePassingQueue
Stuff the queue with elements from the supplier. Semantically similar to: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.- Specified by:
fill
in interfaceMessagePassingQueue<E>
- Overrides:
fill
in classBaseSpscLinkedAtomicArrayQueue<E>
- Returns:
- the number of offered elements
-
capacity
public int capacity()
- Returns:
- the capacity of this queue or
MessagePassingQueue.UNBOUNDED_CAPACITY
if not bounded
