Package io.netty.handler.codec

Extensible decoder and its common implementations which deal with the packet fragmentation and reassembly issue found in a stream-based transport such as TCP/IP.

Interface Summary

Interface	Description
ByteToMessageDecoder.Cumulator	Cumulate ByteBufs.

Class Summary

Class	Description
ByteToMessageCodec<I>	A Codec for on-the-fly encoding/decoding of bytes to messages and vise-versa.
ByteToMessageDecoder	ChannelInboundHandlerAdapter which decodes bytes in a stream-like fashion from one ByteBuf to an other Message type.
DecoderResult
DelimiterBasedFrameDecoder	A decoder that splits the received ByteBufs by one or more delimiters.
Delimiters	A set of commonly used delimiters for DelimiterBasedFrameDecoder.
FixedLengthFrameDecoder	A decoder that splits the received ByteBufs by the fixed number of bytes.
LengthFieldBasedFrameDecoder	A decoder that splits the received ByteBufs dynamically by the value of the length field in the message.
LengthFieldPrepender	An encoder that prepends the length of the message.
LineBasedFrameDecoder	A decoder that splits the received ByteBufs on line endings.
MessageToByteEncoder<I>	ChannelOutboundHandlerAdapter which encodes message in a stream-like fashion from one message to an ByteBuf.
MessageToMessageCodec<INBOUND_IN,OUTBOUND_IN>	A Codec for on-the-fly encoding/decoding of message.
MessageToMessageDecoder<I>	ChannelInboundHandlerAdapter which decodes from one message to an other message.
MessageToMessageEncoder<I>	ChannelOutboundHandlerAdapter which encodes from one message to an other message For example here is an implementation which decodes an Integer to an String.
ProtocolDetectionResult<T>	Result of detecting a protocol.
ReplayingDecoder<S>	A specialized variation of ByteToMessageDecoder which enables implementation of a non-blocking decoder in the blocking I/O paradigm.

Enum Summary

Enum	Description
ProtocolDetectionState	The state of the current detection.

Exception Summary

Exception	Description
CodecException	An Exception which is thrown by a codec.
CorruptedFrameException	An DecoderException which is thrown when the received frame data could not be decoded by an inbound handler.
DecoderException	An CodecException which is thrown by a decoder.
EncoderException	An CodecException which is thrown by an encoder.
PrematureChannelClosureException	A CodecException which is thrown when a Channel is closed unexpectedly before the codec finishes handling the current message, such as missing response while waiting for a request.
TooLongFrameException	An DecoderException which is thrown when the length of the frame decoded is greater than the allowed maximum.
UnsupportedMessageTypeException	Thrown if an unsupported message is received by an codec.
