@ManagedObject @Deprecated(since="2021-05-27") public class MappedByteBufferPool extends Object
Deprecated.The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.A ByteBuffer pool where ByteBuffers are held in queues that are held in a Map.
Given a capacity
factor
of 1024, the Map entry with key1
holds a queue of ByteBuffers each of capacity 1024, the Map entry with key2
holds a queue of ByteBuffers each of capacity 2048, and so on.

acquire
public ByteBuffer acquire(int size, boolean direct)
Deprecated.Description copied from interface:ByteBufferPool
Requests a
ByteBuffer
of the given size.The returned buffer may have a bigger capacity than the size being requested but it will have the limit set to the given size.
- Parameters:
size
- the size of the bufferdirect
- whether the buffer must be direct or not- Returns:
- the requested buffer
- See Also:
ByteBufferPool.release(ByteBuffer)
