Class PropertyMetaData

  • All Implemented Interfaces:
    Serializable, Comparable, ColumnMetaDataContainer

    public class PropertyMetaData
    extends AbstractMemberMetaData
    The property element declares mapping between a virtual field of an implemented interface and the corresponding persistent field of a persistence-capable class. The name attribute is required, and declares the name for the property. The naming conventions for JavaBeans property names is used: the property name is the same as the corresponding get method for the property with the get removed and the resulting name lower-cased. The field-name attribute is required; it associates a persistent field with the named property.
