Support for control system types.
This package contains the data definitions for all the EPICS types. These are in terms of Java interfaces so that each data source can map directly to their own structure.
The interfaces starting with Dbr represent actual types that can be taken by a data source. The other interfaces represent atomic elements that can be treated separately so that generic support can be written against them (i.e. one can write support for alarms regardless of the actual type).
TODO: alarm acknowledgment? Not in this package... TODO: histograms for statistics on enums? TODO: what about toString? Java default? Only value? Full information? TODO: equals and hashcodes? Each object different? Compare on the data only? if we do, what about compare?
