PooledByteBufferAllocator (MINA 1.1.7 API文档

java.lang.Object
- org.apache.mina.common.PooledByteBufferAllocator

所有已实现的接口:

ByteBufferAllocator
```
public class PooledByteBufferAllocator
extends java.lang.Object
implements ByteBufferAllocator
```
A ByteBufferAllocator which pools allocated buffers.
All buffers are allocated with the size of power of 2 (e.g. 16, 32, 64, ...) This means that you cannot simply assume that the actual capacity of the buffer and the capacity you requested are same.

This allocator releases the buffers which have not been in use for a certain period. You can adjust the period by calling setTimeout(int). The default timeout is 1 minute (60 seconds). To release these buffers periodically, a daemon thread is started when a new instance of the allocator is created. You can stop the thread by calling dispose().

构造器和说明
`PooledByteBufferAllocator()` Creates a new instance with the default timeout.
`PooledByteBufferAllocator(int timeout)` Creates a new instance with the specified `timeout`.

限定符和类型	方法和说明
`ByteBuffer`	`allocate(int capacity, boolean direct)` Returns the buffer which is capable of the specified size.
`void`	`dispose()` Stops the thread which releases unused buffers and make this allocator unusable from now on.
`int`	`getTimeout()` Returns the timeout value of this allocator in seconds.
`long`	`getTimeoutMillis()` Returns the timeout value of this allocator in milliseconds.
`void`	`setTimeout(int timeout)` Sets the timeout value of this allocator in seconds.
`ByteBuffer`	`wrap(java.nio.ByteBuffer nioBuffer)` Wraps the specified NIO `ByteBuffer` into MINA buffer.
