java.lang.Objectorg.apache.mina.filter.codec.statemachine.CrLfDecodingState
public abstract class CrLfDecodingState
DecodingState
which decodes a single CRLF
.
If it is found, the bytes are consumed and true
is provided as the product. Otherwise, read bytes are pushed back
to the stream, and false
is provided as the
product.
Note that if we find a CR but do not find a following LF, we raise
an error.

useful when you deal with protocols which don't specify the length of a
message (e.g. HTTP responses without content-length header).
Implement this method to process the remaining data that
