Method Detail

decodeLast

public Object decodeLast(ChannelHandlerContext ctx,
                ByteBuf in)
                  throws Exception

Description copied from class: ByteToMessageDecoder

Is called one last time when the ChannelHandlerContext goes in-active. Which means the ByteToMessageDecoder.channelInactive(ChannelHandlerContext) was triggered. By default this will just call ByteToMessageDecoder.decode(ChannelHandlerContext, ByteBuf) but sub-classes may override this for some special cleanup operation.

Overrides:

decodeLast in class ByteToMessageDecoder

Throws:

Exception

decode

protected Object decode(ChannelHandlerContext ctx,
            ByteBuf buffer)
                 throws Exception

Description copied from class: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read anymore, till nothing was read from the input ByteBuf or till this method returns null.

Specified by:

decode in class ByteToMessageDecoder

Parameters:

ctx - the ChannelHandlerContext which this ByteToByteDecoder belongs to

buffer - the ByteBuf from which to read data

Returns:

message the message to which the content of the ByteBuf was decoded, or null if there was not enough data left in the ByteBuf to decode.

Throws:

Exception - is thrown if an error accour
