Constructor Detail

TextLineDecoder

public TextLineDecoder()

Creates a new instance with the current default Charset and LineDelimiter.AUTO delimiter.

TextLineDecoder

public TextLineDecoder(java.nio.charset.Charset charset)

Creates a new instance with the spcified charset and LineDelimiter.AUTO delimiter.

TextLineDecoder

public TextLineDecoder(java.nio.charset.Charset charset,
               LineDelimiter delimiter)

Creates a new instance with the specified charset and the specified delimiter.

Method Detail

getMaxLineLength

public int getMaxLineLength()

Returns the allowed maximum size of the line to be decoded. If the size of the line to be decoded exceeds this value, the decoder will throw a BufferDataException. The default value is 1024 (1KB).

setMaxLineLength

public void setMaxLineLength(int maxLineLength)

Sets the allowed maximum size of the line to be decoded. If the size of the line to be decoded exceeds this value, the decoder will throw a BufferDataException. The default value is 1024 (1KB).

decode

public void decode(IoSession session,
          ByteBuffer in,
          ProtocolDecoderOutput out)
            throws java.lang.Exception

Description copied from interface: ProtocolDecoder

Decodes binary or protocol-specific content into higher-level message objects. MINA invokes ProtocolDecoder.decode(IoSession, ByteBuffer, ProtocolDecoderOutput) method with read data, and then the decoder implementation puts decoded messages into ProtocolDecoderOutput.

Specified by:

decode in interface ProtocolDecoder

Throws:

java.lang.Exception - if the read data violated protocol specification

finishDecode

public void finishDecode(IoSession session,
                ProtocolDecoderOutput out)
                  throws java.lang.Exception

Description copied from interface: ProtocolDecoder

Invoked when the specified session is closed. This method is useful when you deal with the protocol which doesn't specify the length of a message such as HTTP response without content-length header. Implement this method to process the remaining data that ProtocolDecoder.decode(IoSession, ByteBuffer, ProtocolDecoderOutput) method didn't process completely.

Specified by:

finishDecode in interface ProtocolDecoder

Throws:

java.lang.Exception - if the read data violated protocol specification

dispose

public void dispose(IoSession session)
             throws java.lang.Exception

Description copied from interface: ProtocolDecoder

Releases all resources related with this decoder.

Specified by:

dispose in interface ProtocolDecoder

Throws:

java.lang.Exception - if failed to dispose all resources
