Using Java SDO classes to access Property meta data

The OpenEdge ProDataGraph relies on the Java SDO Type and Property interfaces to encapsulate the base DataObject interface meta data for the columns of a ProDataObject. This meta data specifies both the list of Property objects (properties) that define a DataObject and specifies the Java data types that define the individual column properties and whether the properties are single- or many-valued. For a ProDataObject, the ProDataObjectMetaData then maps the schema information for temp-table fields to the corresponding Property objects.

This section describes the Type and Property interfaces in terms of base DataObject meta data support with reference to the OpenEdge ProDataGraph, as appropriate.
