DDSJAVA — Logically ordered types should implement java.lang.Comparable

RTI (Rick Warren, rick.warren@rti.com)

Summary:

Several of the types defined in this PSM have a natural order (such as Time). In order to better integrate with the Java platform, these types should implement the standard java.lang.Comparable interface.

Proposed Resolution:

Implement Comparable in the following types:

· Bit—ordered based on index within a bit set

· Duration—ordered from shorter durations to longer ones

· Time—ordered from earlier points in time to later ones

Implement Comparable in the following types:
• Bit—ordered based on index within a bit set
• Duration—ordered from shorter durations to longer ones
• InstanceHandle—ordered in an implementation-specific way (DDS specification of DataReader::read() requires such an ordering)
• Time—ordered from earlier points in time to later ones
