Method Summary

Modifier and Type	Method and Description
Buffer	create(ByteBuf value) Creates a new Buffer given a T instance.
static void	readRaw(Buffer buffer, Consumer<ByteBuf> consumer) Utility method to allow reading from the underlying bytes using a Netty ByteBuf instance for interoperability, advancing the reader index of the Buffer after the consumer is called.
Buffer	wrap(ByteBuffer value) Wraps a NIO buffer.
static void	writeRaw(Buffer buffer, Consumer<ByteBuf> consumer) Allows writing from the underlying bytes using a Netty ByteBuf instance for interoperability, advancing the writer index of the Buffer after the consumer is called.

Method Detail

create

public Buffer create(ByteBuf value)

Description copied from interface: BufferFactory

Creates a new Buffer given a T instance.

Specified by:

create in interface BufferFactory<ByteBuf>

Returns:

wrap

public Buffer wrap(ByteBuffer value)

Description copied from interface: BufferFactory

Wraps a NIO buffer.

Specified by:

wrap in interface BufferFactory<ByteBuf>

readRaw

public static void readRaw(Buffer buffer,
                           Consumer<ByteBuf> consumer)

Utility method to allow reading from the underlying bytes using a Netty ByteBuf instance for interoperability, advancing the reader index of the Buffer after the consumer is called. Note that the ByteBuf used by the consumer should not be released by the caller. In case the provided Buffer instance is not a NettyBuffer, it will create a ByteBuf wrapper for the consumer to use, releasing it after use.

writeRaw

public static void writeRaw(Buffer buffer,
                            Consumer<ByteBuf> consumer)

Allows writing from the underlying bytes using a Netty ByteBuf instance for interoperability, advancing the writer index of the Buffer after the consumer is called. Note that the ByteBuf used by the consumer should not be released by the caller. In case the provided Buffer instance is not a NettyBuffer, it will create a ByteBuf wrapper for the consumer to use, releasing it after use.
