org.eclipse.jetty.io.ArrayByteBufferPool.Tracking

All Implemented Interfaces:

ByteBufferPool, Dumpable

Enclosing class:

ArrayByteBufferPool

public static class ArrayByteBufferPool.Tracking
extends ArrayByteBufferPool

asRetainableByteBufferPool

public RetainableByteBufferPool asRetainableByteBufferPool()

Description copied from interface: ByteBufferPool

Get this pool as a RetainableByteBufferPool, which supports reference counting of the buffers and possibly a more efficient lookup mechanism based on the Pool class.

Specified by:

asRetainableByteBufferPool in interface ByteBufferPool

Returns:

This pool as a RetainableByteBufferPool. The same instance is always returned by multiple calls to this method.
