Constructor Details

NettyByteBufferFactory

public NettyByteBufferFactory()

Default constructor.

NettyByteBufferFactory

public NettyByteBufferFactory(io.netty.buffer.ByteBufAllocator allocator)

Parameters:

allocator - The ByteBufAllocator

Method Details

getNativeAllocator

public io.netty.buffer.ByteBufAllocator getNativeAllocator()

Specified by:

getNativeAllocator in interface ByteBufferFactory<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Returns:

The native allocator

buffer

public ByteBuffer<io.netty.buffer.ByteBuf> 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<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Returns:

The buffer

buffer

public ByteBuffer<io.netty.buffer.ByteBuf> 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<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Parameters:

initialCapacity - The initial capacity

Returns:

the buffer

buffer

public ByteBuffer<io.netty.buffer.ByteBuf> 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<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Parameters:

initialCapacity - The initial capacity

maxCapacity - The maximum capacity

Returns:

The buffer

copiedBuffer

public ByteBuffer<io.netty.buffer.ByteBuf> 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<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Parameters:

bytes - The bytes

Returns:

The buffer

copiedBuffer

public ByteBuffer<io.netty.buffer.ByteBuf> 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<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Parameters:

nioBuffer - The nioBuffer

Returns:

The buffer

wrap

public ByteBuffer<io.netty.buffer.ByteBuf> wrap(io.netty.buffer.ByteBuf existing)

Description copied from interface: ByteBufferFactory

Wrap an existing buffer.

Specified by:

wrap in interface ByteBufferFactory<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Parameters:

existing - The buffer to wrap

Returns:

The wrapped ByteBuffer

wrap

public ByteBuffer<io.netty.buffer.ByteBuf> wrap(byte[] existing)

Description copied from interface: ByteBufferFactory

Wrap an existing buffer.

Specified by:

wrap in interface ByteBufferFactory<io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBuf>

Parameters:

existing - The bytes to wrap

Returns:

The wrapped ByteBuffer
