NOTE: This class was automatically generated by org.jctools.queues.varhandle.JavaParsingVarHandleLinkedQueueGenerator which can found in the jctools-build module. The original source file is SpscGrowableArrayQueue.java. An SPSC 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.
