Type Parameters:

T -

All Implemented Interfaces:

Iterable<T>, Collection<T>, BlockingQueue<T>, Queue<T>, WaterMarkQueue<T>

public class DefaultWaterMarkQueue<T>
extends Object
implements WaterMarkQueue<T>

A Default implementation for WaterMarkQueue interface. The implementation uses an ArrayBlockingQueue up to water mark. Then it uses a LinkedBlockingQueue or ArrayBlocking queue from the water mark point. The LinkedBlockingQueue is used if a queue size is specified other than the waterMark.

Constructor Detail

DefaultWaterMarkQueue

public DefaultWaterMarkQueue(int waterMark)

Create a WaterMarkQueue with a waterMark. The queue will first fill up to waterMark. These items will be inserted in to an ArrayBlockingQueue. After this an LinkedBlockingQueue will be used without a bound.

Parameters:

waterMark - the waterMark of the queue

DefaultWaterMarkQueue

public DefaultWaterMarkQueue(int waterMark,
                             int size)

Create a WaterMarkQueue with a waterMark. The queue will first fill up to waterMark. These items will be inserted in to an ArrayBlockingQueue. After this an LinkedBlockingQueue will be used with capacity size - waterMark.

Parameters:

waterMark - the waterMark of the queue

size - the size of the queue
