Method Detail

encodeFrame

public static io.netty.buffer.ByteBuf encodeFrame(io.netty.buffer.ByteBufAllocator bufAllocator,
                                                  ThriftFrame frame)

Encodes the HeaderFrame into a ByteBuf transferring the reference ownership.

Parameters:

bufAllocator -

frame - frame to be encoded; reference count ownership is transferred to this method

Returns:

the encoded frame data; caller is responsible for releasing this buffer

decodeFrame

public static ThriftFrame decodeFrame(io.netty.buffer.ByteBufAllocator bufAllocator,
                                      io.netty.buffer.ByteBuf buffer)

Decodes the ByteBuf into a HeaderFrame transferring the reference ownership.

Parameters:

bufAllocator - allocator to allocated byteBuf to contain decoded result.

buffer - buffer to be decoded; reference count ownership is transferred to this method

Returns:

the decoded frame; caller is responsible for releasing this object

tryDecodeFrameInfo

public static Optional<FrameInfo> tryDecodeFrameInfo(io.netty.buffer.ByteBufAllocator bufAllocator,
                                                     io.netty.buffer.ByteBuf input)
