public NettyDataBufferFactory setDefaultInitialCapacity(int defaultInitialCapacity)

Specified by:

setDefaultInitialCapacity in interface DataBufferFactory

allocateBuffer

public NettyDataBuffer allocateBuffer()

Specified by:

allocateBuffer in interface DataBufferFactory

allocateBuffer

public NettyDataBuffer allocateBuffer(int initialCapacity)

Specified by:

allocateBuffer in interface DataBufferFactory

wrap

public NettyDataBuffer wrap(ByteBuffer byteBuffer)

Specified by:

Specified by:

wrap in interface DataBufferFactory

wrap

public DataBuffer wrap(byte[] bytes,
 int offset,
 int length)

wrap

public NettyDataBuffer wrap(io.netty.buffer.ByteBuf byteBuf)

Wrap the given Netty ByteBuf in a NettyDataBuffer.

Parameters:

byteBuf - the Netty byte buffer to wrap

Returns:

the wrapped buffer

join

public DataBuffer join(List<? extends DataBuffer> dataBuffers)

This implementation uses Netty's CompositeByteBuf.

Specified by:

join in interface DataBufferFactory

toByteBuf

public static io.netty.buffer.ByteBuf toByteBuf(DataBuffer dataBuffer)

Return the given Netty DataBuffer as a ByteBuf.

Returns the native buffer if dataBuffer is a NettyDataBuffer; returns Unpooled.wrappedBuffer(ByteBuffer) otherwise.

Parameters:

dataBuffer - the DataBuffer to return a ByteBuf for

Returns:

the netty ByteBuf

toString

public String toString()

Overrides:

toString in class Object
