BoneCP源码——BoneCP中使用的队列
TransferQueue<ConnectionHandle> connectionHandles;public interface TransferQueue<E> extends BlockingQueue<E> {}
if (config.getMaxConnectionsPerPartition() == config.getMinConnectionsPerPartition()){// if we have a pool that we don't want resized, make it even faster by ignoring// the size constraints.connectionHandles = queueLIFO ? new LIFOQueue<ConnectionHandle>() : new LinkedTransferQueue<ConnectionHandle>();} else {connectionHandles = queueLIFO ? new LIFOQueue<ConnectionHandle>(this.config.getMaxConnectionsPerPartition()) : new BoundedLinkedTransferQueue<ConnectionHandle>(this.config.getMaxConnectionsPerPartition());}?如果设置了queueLIFO，则使用LIFOQueue队列，该队列继承LinkedBlockingDeque：
public class LIFOQueue<E> extends LinkedBlockingDeque<E> implements TransferQueue<E>{}static final class Node<E> { E item; Node<E> prev; Node<E> next; Node(E x) { item = x; } }
/** Maximum number of items in the deque */ private final int capacity; public LinkedBlockingDeque() { this(Integer.MAX_VALUE); } public LinkedBlockingDeque(int capacity) { if (capacity <= 0) throw new IllegalArgumentException(); this.capacity = capacity; }
/** Main lock guarding all access */ final ReentrantLock lock = new ReentrantLock(); /** Condition for waiting takes */ private final Condition notEmpty = lock.newCondition(); /** Condition for waiting puts */ private final Condition notFull = lock.newCondition();
/** No of elements in queue. */private AtomicInteger size = new AtomicInteger();/** bound of queue. */private final int maxQueueSize;/** Main lock guarding all access */private final ReentrantLock lock = new ReentrantLock();public BoundedLinkedTransferQueue(int maxQueueSize){this.maxQueueSize = maxQueueSize;}
