Class AbstractExtensionFactory

  • All Implemented Interfaces:
    ExtensionFactory
    Direct Known Subclasses:
    MediaExtensionFactory
    public abstract class AbstractExtensionFactory
extends java.lang.Object
implements ExtensionFactory

    Provides a base implementation for ExtensionFactory instances. By extending this, specific extension factories need only to associate a QName with an implementation class, e.g., 

      public class MyExtensionFactory
    extends AbstractExtensionFactory {
 
    private String NS = "http://example.org/foo/ns"; 
    private QName FOO = new QName(NS, "foo");
 
    public MyExtensionFactory() {
      super(NS);
      addImpl(FOO, Foo.class);
    }
  }
  
  public class Foo extends ElementWrapper { ... }

      • getElementWrapper

        public <T extends Element> T getElementWrapper​(Element internal)
        Description copied from interface: ExtensionFactory
        Abdera's support for static extensions is based on a simple delegation model. Static extension interfaces wrap the dynamic extension API. ExtensionFactory's are handed the internal dynamic element instance and are expected to hand back an object wrapper.
        Specified by:
        getElementWrapper in interface ExtensionFactory
        Parameters:
        internal - The Abdera element that needs to be wrapped
        Returns:
        The wrapper element

      • getMimeType

        public <T extends Base> java.lang.String getMimeType​(T base)
        Description copied from interface: ExtensionFactory
        Retrieve the mime type for the element
        Specified by:
        getMimeType in interface ExtensionFactory
        Parameters:
        base - An Abdera object
        Returns:
        A MIME media type for the object

      • getNamespaces

        public java.lang.String[] getNamespaces()
        Description copied from interface: ExtensionFactory

        public boolean handlesNamespace​(java.lang.String namespace)
        Description copied from interface: ExtensionFactory
        Returns true if this extension factory handles the specified namespace
        Specified by:
        handlesNamespace in interface ExtensionFactory
        Parameters:
        namespace - The XML namespace of the extension
        Returns:
