Examples of org.apache.qpid.protocol.AMQConstant

org.apache.qpid.protocol.AMQConstant
Defines constants for AMQP codes and also acts as a factory for creating such constants from the raw codes. Each constant also defines a short human readable description of the constant. @todo Why would a constant be defined that is not in the map? Seems more natural that getConstant should raise anexception for an unknown constant. Or else provide an explanation of why this is so. Also, there is no way for callers to determine the unknown status of a code except by comparing its name to "unknown code", which would seem to render this scheme a little bit pointless? @todo Java has a nice enum construct for doing this sort of thing. Maybe this is done in the old style for Java 1.4backward compatability? Now that is handled through retrotranslater it may be time to use enum.
CRC Card Responsibilities Collaborations Define the set of AMQP status codes. Provide a factory to lookup constants by their code.
