Constructor Detail

OrdImageSignatureDomain

public OrdImageSignatureDomain()

Constructs a new OrdImageSignatureDomain instance. The user can insert a new row with an empty ORDSYS.OrdImageSignature SQL object using the following code snippet:

   OrdImageSignatureDomain sigDomain = new OrdImageSignatureDomain();
   Row row = viewObject.createRow();
   row.setAttribute("Signature", sigDomain);
   viewObject.insertRow(row);
   appModule.getTransaction().postChanges();
 

Method Detail

getFactory

public static oracle.sql.CustomDatumFactory getFactory()

   OrdImageSignatureDomain sig =
      (OrdImageSignatureDomain)rset.getCustomDatum(
        1, OrdImageSignatureDomain.getFactory() );
 

Returns:

the OrdImageSignatureDomain implementation of the CustomDatumFactory interface
