The remainder of this topic defines the additional OM classes used to represent values of the selected attributes described in Selected Attribute Types. Some of the selected attributes are represented by OM classes that are used in the interface itself, and hence are defined in XDS Class Definitions; for example, DS_C_NAME.
This subtopic shows the hierarchical organization of the OM classes that are defined in the following subtopics, and it shows which OM classes inherit additional OM attributes from their OM superclasses. In the following list, subclassification is indicated by indentation, and the names of abstract OM classes are in italics. For example, DS_C_POSTAL_ADDRESS is an immediate subclass of the abstract OM class OM_C_OBJECT.
OM_C_OBJECT
· DS_C_FACSIMILE_PHONE_NBR
· DS_C_POSTAL_ADDRESS
· DS_C_SEARCH_CRITERION
· DS_C_SEARCH_GUIDE
· DS_C_TELETEX_TERM_IDENT
· DS_C_TELEX_NBR
None of the OM classes in the preceding list are encodable by using om_encode( ) and om_decode( ).
