    - #### DEFAULT

          public static final java.lang.String DEFAULT

      constant for defining the default value
      See Also:
        Constant Field Values

    - #### foObjs

          protected java.util.HashMap<java.lang.String,ElementMapping.Maker> foObjs

      The HashMap table of formatting objects defined by the ElementMapping

    - #### namespaceURI

          protected java.lang.String namespaceURI

      The namespace for the ElementMapping

  - ### Constructor Detail

    - #### ElementMapping

          public ElementMapping()

  - ### Method Detail

    - #### getTable

          public java.util.HashMap<java.lang.String,ElementMapping.Maker> getTable()

      Returns a HashMap of maker objects for this element mapping
      Returns:
        Table of Maker objects for this ElementMapping

    - #### getNamespaceURI

          public java.lang.String getNamespaceURI()

      Returns the namespace URI for this element mapping
      Returns:
        Namespace URI for this element mapping

    - #### getDOMImplementation

          public org.w3c.dom.DOMImplementation getDOMImplementation()

      Returns the DOMImplementation used by this ElementMapping. The value returned may be null for cases where no DOM is used to represent the element tree (XSL-FO, for example). This method is used by the intermediate format to instantiate the right kind of DOM document for foreign objects. For example, SVG handled through Apache Batik has to use a special DOMImplementation.
      Returns:
        the DOMImplementation used by this ElementMapping, may be null

    - #### getDefaultDOMImplementation

          public static org.w3c.dom.DOMImplementation getDefaultDOMImplementation()

      Returns:
        the default DOMImplementation when no specialized DOM is necessary.

    - #### getStandardPrefix

          public java.lang.String getStandardPrefix()

      Returns:
        the standard namespace prefix for this namespace or null if it is not known.

    - #### isAttributeProperty

          public boolean isAttributeProperty(org.apache.xmlgraphics.util.QName attributeName)

      Indicates whether a particular attribute of the namespace is a property, i.e. the attribute value should be converted to a property value.
      Parameters:
        `attributeName` - the attribute name
      Returns:
        true if the attribute should be converted to a property

    - #### initialize

          protected abstract void initialize()

      Initializes the set of maker objects associated with this ElementMapping
