public abstract class ElementMapping extends Object
Abstract base class for Element Mappings (including FO Element Mappings) which provide the framework of valid elements and attributes for a given namespace.

  • Field Details

    • DEFAULT

      public static final String DEFAULT
      constant for defining the default value
      See Also:

    • foObjs

      protected HashMap<String,ElementMapping.Maker> foObjs
      The HashMap table of formatting objects defined by the ElementMapping

    • namespaceURI

      protected String namespaceURI
      The namespace for the ElementMapping

  • Constructor Details

    • ElementMapping

      public ElementMapping()

  • Method Details

    • getTable

      public HashMap<String,ElementMapping.Maker> getTable()
      Returns a HashMap of maker objects for this element mapping
      Returns:
      Table of Maker objects for this ElementMapping

    • getNamespaceURI

      public String getNamespaceURI()
      Returns the namespace URI for this element mapping
      Returns:
      Namespace URI for this element mapping

    • getDOMImplementation

      public 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 DOMImplementation getDefaultDOMImplementation()
      Returns:
      the default DOMImplementation when no specialized DOM is necessary.

    • getStandardPrefix

      public 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
