Nested Class Summary

class

IoBufferDecoder.DecodingContext

Constructor Summary

IoBufferDecoder(byte[] delimiter)
Creates a new instance that uses specified delimiter byte array as a message delimiter.

IoBufferDecoder(int contentLength)
Creates a new instance that will read messages of contentLength bytes.

Method Summary

IoBuffer	decodeFully(IoBuffer in) Will return null unless it has enough data to decode.
void	setContentLength(int contentLength, boolean resetMatchCount) Sets the the length of the content line to be decoded.
void	setDelimiter(byte[] delim, boolean resetMatchCount) Dynamically sets a new delimiter.

Constructor Detail

IoBufferDecoder

public IoBufferDecoder(byte[] delimiter)

Creates a new instance that uses specified delimiter byte array as a message delimiter.

IoBufferDecoder

public IoBufferDecoder(int contentLength)

Creates a new instance that will read messages of contentLength bytes.

Method Detail

setContentLength

public void setContentLength(int contentLength,
                             boolean resetMatchCount)

Sets the the length of the content line to be decoded. When set, it overrides the dynamic delimiter setting. The default value is -1. Content length method will be used for decoding on the next decodeOnce call. Delimiter matching is reset only if resetMatchCount is true.

setDelimiter

public void setDelimiter(byte[] delim,
                         boolean resetMatchCount)

Dynamically sets a new delimiter. Next time IoBufferDecoder#decodeOnce(IoSession, int) will be called it will use the new delimiter. Delimiter matching is reset only if resetMatchCount is true but decoding will continue from current position. NB : Delimiter LineDelimiter.AUTO is not allowed.

decodeFully

public IoBuffer decodeFully(IoBuffer in)

Will return null unless it has enough data to decode. If contentLength is set then it tries to retrieve contentLength bytes from the buffer otherwise it will scan the buffer to find the data delimiter and return all the data and the trailing delimiter.
