Detailed Description

Encapsulate a TRANSPORT_PRIORITY value.

This interface allows a TRANSPORT_PRIORIY value to be mapped to values to use as DiffServ codepoint and thread priority values. Specific implementations of this interface can define specific mapping algorithms for conversion from the basic TRANSPORT_PRIORITY value to the values to use for network and thread prirorities.

We take our cue from the RTCORBA code base in defining the types of the priority values mapped to. RTCORBA defines both the network and thread priority values as shorts. Since this is well within the expected range of priority values to be mapped to and the short value can be expanded into larger types without complaint, this priority type should be without problem here.
