Method Detail

getXsQueueSupplier

public static <T> Supplier<Queue<T>> getXsQueueSupplier()

get

public static <T> Supplier<Queue<T>> get(int bufferSize)

Gets a supplier to create queues with the given buffer size (size of the array allocated as backend of the queue).

The type of the queue and configuration is computed based on the given buffer size.

Type Parameters:

T - the type of element

Parameters:

bufferSize - the buffer size

Returns:

the supplier.

unbounded

public static <T> Supplier<Queue<T>> unbounded(int size)

Returns an unbounded Queue. The queue is array-backed. Each array has the given size. If the queue is full, new arrays can be allocated.

Type Parameters:

T - the type of item

Parameters:

size - the size of the array

Returns:

the unbound queue supplier

createMpscQueue

public static <T> Queue<T> createMpscQueue()

Creates a new multi-producer single consumer unbounded queue.

Type Parameters:

T - the type of item

Returns:

the queue

createStrictSizeQueue

public static <T> Queue<T> createStrictSizeQueue(int size)
