类型参数:

R - the type of the resource

所有已实现的接口:

Serializable, Iterable<R>, Collection<R>, Queue<R>, PoolMap.Pool<R>

封闭类:

public static class PoolMap.ReusablePool<R>
extends ConcurrentLinkedQueue<R>
implements PoolMap.Pool<R>

The ReusablePool represents a PoolMap.Pool that builds on the LinkedList class. It essentially allows resources to be checked out, at which point it is removed from this pool. When the resource is no longer required, it should be returned to the pool in order to be reused.

If maxSize is set to Integer.MAX_VALUE, then the size of the pool is unbounded. Otherwise, it caps the number of consumers that can check out a resource from this pool to the (non-zero positive) value specified in maxSize.
