org.das2.datum.EnumerationUnits

Units class for mapping arbitrary objects to Datums. Nothing about the contract for a Datum requires that they correspond to physical quantities, and we can assign a mapping from numbers to objects using this class. This allows information such as "Cluster 1" or "Spin Flip" to be encoded. This is used to model ordinal or nominal data, as described in http://en.wikipedia.org/wiki/Level_of_measurement

createDatum

createDatum( int ival, Object sval, int color ) → Datum

creates the datum, explicitly setting the ordinal. Use with caution.

Returns:

the Datum, which may have been created already.
