public Class MpscGrowableArrayQueue<E>

extends MpscChunkedArrayQueue<E>
Class Inheritance
Imports
io.netty.util.internal.shaded.org.jctools.util.Pow2, .RangeUtil
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.
