Package io.netty.handler.codec

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.

Class	Description
AsciiHeadersEncoder
AsciiHeadersEncoder.NewlineType	The newline characters to insert between header entries.
AsciiHeadersEncoder.SeparatorType	The separator characters to insert between a header name and a header value.
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 another Message type.
ByteToMessageDecoder.Cumulator	Cumulate ByteBufs.
CharSequenceValueConverter	Converts to/from native types, general Object, and CharSequences.
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.
DatagramPacketDecoder	A decoder that decodes the content of the received DatagramPacket using the specified ByteBuf decoder.
DatagramPacketEncoder<M>	An encoder that encodes the content in AddressedEnvelope to DatagramPacket using the specified message encoder.
DateFormatter	A formatter for HTTP header dates, such as "Expires" and "Date" headers, or "expires" field in "Set-Cookie".
DecoderException	An CodecException which is thrown by a decoder.
DecoderResult
DecoderResultProvider	Provides the accessor methods for the DecoderResult property of a decoded message.
DefaultHeaders<K, V, T extends Headers<K,V,T>>	Default implementation of Headers;
DefaultHeaders.HeaderEntry<K,V>
DefaultHeaders.NameValidator<K>
DefaultHeaders.ValueValidator<V>
DefaultHeadersImpl<K,V>	A concrete implementation of DefaultHeaders that allows for direct instantiation.
DelimiterBasedFrameDecoder	A decoder that splits the received ByteBufs by one or more delimiters.
Delimiters	A set of commonly used delimiters for DelimiterBasedFrameDecoder.
EmptyHeaders<K, V, T extends Headers<K,V,T>>
EncoderException	An CodecException which is thrown by an encoder.
FixedLengthFrameDecoder	A decoder that splits the received ByteBufs by the fixed number of bytes.
Headers<K, V, T extends Headers<K,V,T>>	Common interface for Headers which represents a mapping of key to value.
HeadersUtils	Provides utility methods related to Headers.
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.
MessageAggregationException	Raised by MessageAggregator when aggregation fails due to an unexpected message sequence.
MessageAggregator<I, S, C extends ByteBufHolder, O extends ByteBufHolder>	An abstract ChannelHandler that aggregates a series of message objects into a single aggregated message.
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.
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.
ProtocolDetectionResult<T>	Result of detecting a protocol.
ProtocolDetectionState	The state of the current detection.
ReplayingDecoder<S>	A specialized variation of ByteToMessageDecoder which enables implementation of a non-blocking decoder in the blocking I/O paradigm.
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.
UnsupportedValueConverter<V>	UnsupportedOperationException will be thrown from all ValueConverter methods.
ValueConverter<T>	Converts to/from a generic object to the type.
