@Deprecated(since="2021-05-27")
public interface ByteBufferPool

Deprecated.

The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.

A ByteBuffer pool.

Acquired buffers may be released but they do not need to; if they are released, they may be recycled and reused, otherwise they will be garbage collected as usual.

Method Detail

acquire

java.nio.ByteBuffer acquire(int size,
                            boolean direct)

Deprecated.

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 buffer

direct - whether the buffer must be direct or not

Returns:

the requested buffer

See Also:

release(ByteBuffer)

release

void release(java.nio.ByteBuffer buffer)

Deprecated.

Returns a ByteBuffer, usually obtained with acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.

Parameters:

buffer - the buffer to return

See Also:

acquire(int, boolean)

remove

default void remove(java.nio.ByteBuffer buffer)

Deprecated.

Removes a ByteBuffer that was previously obtained with acquire(int, boolean).

The buffer will not be available for further reuse.

Parameters:

buffer - the buffer to remove

See Also:

acquire(int, boolean), release(ByteBuffer)

newByteBuffer

default java.nio.ByteBuffer newByteBuffer(int capacity,
                                          boolean direct)

Deprecated.

Creates a new ByteBuffer of the given capacity and the given directness.

Parameters:

capacity - the ByteBuffer capacity

direct - the ByteBuffer directness

Returns:

a newly allocated ByteBuffer
