Examples of commonj.sdo.Sequence

commonj.sdo.Sequence
A sequence is a heterogeneous list of {@link Property properties} and corresponding values.It represents an ordered arbitrary mixture of data values from more than one property of a {@link DataObject data object}.

    if (javaClassFeature == null)
    {
      javaClassFeature = BasicExtendedMetaData.INSTANCE.getAttribute("commonj.sdo/java", "javaClass");
    }


    Sequence anyAttribute = getAnyAttribute();
    int count = anyAttribute.size();
    for (int i = 0; i < count; i++)
    {
      EStructuralFeature eFeature = (EStructuralFeature)anyAttribute.getProperty(i);
      if (eFeature == javaClassFeature)
      {
        return (String)anyAttribute.getValue(i);
      }
    }
    return null;
