Module io.netty5.codec

Package io.netty5.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 Buffers.
DecoderResultProvider	Provides the accessor methods for the DecoderResult property of a decoded message.
DefaultHeaders.NameValidator<K>
Headers<K,V,T extends Headers<K,V,T>>	Common interface for Headers which represents a mapping of key to value.
ProtocolEvent	An application-level event propagated via an ChannelPipeline, such as a TLS or WebSocket handshake event.
ValueConverter<T>	Converts to/from a generic object to the type.

Class Summary

Class	Description
ByteToMessageCodec<I>	A Codec for on-the-fly encoding/decoding of bytes to messages and vise-versa.
ByteToMessageDecoder	ChannelHandler which decodes bytes in a stream-like fashion from one Buffer to an other Message type.
CharSequenceValueConverter	Converts to/from native types, general Object, and CharSequences.
DatagramPacketDecoder	A decoder that decodes the content of the received DatagramPacket using the specified Buffer 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".
DecoderResult
DefaultHeaders<K,V,T extends Headers<K,V,T>>	Default implementation of Headers;
DefaultHeaders.HeaderEntry<K,V>
DefaultHeadersImpl<K,V>	A concrete implementation of DefaultHeaders that allows for direct instantiation.
DelimiterBasedFrameDecoder	A decoder that splits the received Buffers by one or more delimiters.
Delimiters	A set of commonly used delimiters for DelimiterBasedFrameDecoder.
EmptyHeaders<K,V,T extends Headers<K,V,T>>
FixedLengthFrameDecoder	A decoder that splits the received Buffers by the fixed number of bytes.
HeadersUtils	Provides utility methods related to Headers.
LengthFieldBasedFrameDecoder	A decoder that splits the received Buffers 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 Buffers on line endings.
MessageAggregator<I,S,C extends AutoCloseable,A extends AutoCloseable>	An abstract ChannelHandler that aggregates a series of message objects into a single aggregated message.
MessageToByteEncoder<I>	ChannelHandler which encodes message in a stream-like fashion from one message to a Buffer.
MessageToMessageCodec<INBOUND_IN,OUTBOUND_IN>	A Codec for on-the-fly encoding/decoding of message.
MessageToMessageDecoder<I>	ChannelHandler which decodes from one message to another message.
MessageToMessageEncoder<I>	ChannelHandler which encodes from one message to another message For example here is an implementation which decodes an Integer to an String.
ProtocolDetectionResult<T>	Result of detecting a protocol.
UnsupportedValueConverter<V>	UnsupportedOperationException will be thrown from all ValueConverter methods.

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.
MessageAggregationException	Raised by MessageAggregator when aggregation fails due to an unexpected message sequence.
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 a codec.
