Method Details

getNativeAllocator

public Void getNativeAllocator()

Specified by:

getNativeAllocator in interface ByteBufferFactory<Void,byte[]>

Returns:

The native allocator

buffer

public ByteArrayByteBuffer buffer()

Description copied from interface: ByteBufferFactory

Allocate a ByteBuffer. If it is a direct or heap buffer depends on the actual implementation.

Specified by:

buffer in interface ByteBufferFactory<Void,byte[]>

Returns:

The buffer

buffer

public ByteArrayByteBuffer buffer(int initialCapacity)

Description copied from interface: ByteBufferFactory

Allocate a ByteBuffer with the given initial capacity. If it is a direct or heap buffer depends on the actual implementation.

Specified by:

buffer in interface ByteBufferFactory<Void,byte[]>

Parameters:

initialCapacity - The initial capacity

Returns:

the buffer

buffer

public ByteArrayByteBuffer buffer(int initialCapacity,
 int maxCapacity)

Description copied from interface: ByteBufferFactory

Allocate a ByteBuffer with the given initial capacity and the given maximal capacity. If it is a direct or heap buffer depends on the actual implementation.

Specified by:

buffer in interface ByteBufferFactory<Void,byte[]>

Parameters:

initialCapacity - The initial capacity

maxCapacity - The maximum capacity

Returns:

The buffer

copiedBuffer

public ByteArrayByteBuffer copiedBuffer(byte[] bytes)

Description copied from interface: ByteBufferFactory

Creates a new big-endian buffer whose content is a copy of the specified array's sub-region. The new buffer's readerIndex and writerIndex are 0 and the specified length respectively.

Specified by:

copiedBuffer in interface ByteBufferFactory<Void,byte[]>

Parameters:

bytes - The bytes

Returns:

The buffer

copiedBuffer

public ByteArrayByteBuffer copiedBuffer(ByteBuffer nioBuffer)

Description copied from interface: ByteBufferFactory

Creates a new big-endian buffer whose content is a copy of the specified NIO buffer. The new buffer's readerIndex and writerIndex are 0 and the specified length respectively.

Specified by:

copiedBuffer in interface ByteBufferFactory<Void,byte[]>

Parameters:

nioBuffer - The nioBuffer

Returns:

The buffer

wrap

public ByteArrayByteBuffer wrap(byte[] existing)

Description copied from interface: ByteBufferFactory

Wrap an existing buffer.

Specified by:

wrap in interface ByteBufferFactory<Void,byte[]>

Parameters:

existing - The buffer to wrap

Returns:

The wrapped ByteBuffer
