NOTE: This class was automatically generated by org.jctools.queues.atomic.unpadded.JavaParsingAtomicUnpaddedLinkedQueueGenerator which can found in the jctools-build module. The original source file is MpscGrowableArrayQueue.java. An MPSC array queue which starts at initialCapacity and grows to maxCapacity in linked chunks, doubling theirs size every time until the full blown backing array is used. 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.

Constructor Details

MpscGrowableAtomicUnpaddedArrayQueue

public MpscGrowableAtomicUnpaddedArrayQueue(int maxCapacity)

MpscGrowableAtomicUnpaddedArrayQueue

public MpscGrowableAtomicUnpaddedArrayQueue(int initialCapacity,
 int maxCapacity)

Parameters:

initialCapacity - the queue initial capacity. If chunk size is fixed this will be the chunk size. Must be 2 or more.

maxCapacity - the maximum capacity will be rounded up to the closest power of 2 and will be the upper limit of number of elements in this queue. Must be 4 or more and round up to a larger power of 2 than initialCapacity.

Method Details

getNextBufferSize

protected int getNextBufferSize(AtomicReferenceArray<E> buffer)

Overrides:

getNextBufferSize in class MpscChunkedAtomicUnpaddedArrayQueue<E>

Returns:

next buffer size(inclusive of next array pointer)

getCurrentBufferCapacity

protected long getCurrentBufferCapacity(long mask)

Overrides:

getCurrentBufferCapacity in class MpscChunkedAtomicUnpaddedArrayQueue<E>

Returns:

current buffer capacity for elements (excluding next pointer and jump entry) * 2
