* The class implements several convenience methods to provides class specific static arguments to the argument
* list of the DataTableRow base class methods. Base class methods are used to set or modify the values and states
* of the contained DataObjects. Because the base class uses a JDBC connection class (see org.trinet.jdbc.JDBConnect)
* to access the database containing the table described by this object, a connection object must be instantiated before
* using any of the database enabled methods of this class.
* Object states refering to data update, nullness, and mutability are inhereited from the DataTableRow base class
* implementation of the DataState interface. These state conditions are used to control the methods access to the
* object and its contained DataObjects, which also implement the DataState interface.
* The default constructor sets the default states to: setUpdate(false), setNull(true), setMutable(true), and
* setProcessing(NONE).
