Class ExtensionNamespacesManager

java.lang.Object
org.apache.xalan.extensions.ExtensionNamespacesManager

public class ExtensionNamespacesManager extends Object
Used during assembly of a stylesheet to collect the information for each extension namespace that is required during the transformation process to generate an ExtensionHandler.
  • Constructor Details

    • ExtensionNamespacesManager

      public ExtensionNamespacesManager()
      An ExtensionNamespacesManager is instantiated the first time an extension function or element is found in the stylesheet. During initialization, a vector of ExtensionNamespaceSupport objects is created, one for each predefined extension namespace.
  • Method Details

    • registerExtension

      public void registerExtension(String namespace)
      If necessary, register the extension namespace found compiling a function or creating an extension element. If it is a predefined namespace, create a support object to simplify the instantiate of an appropriate ExtensionHandler during transformation runtime. Otherwise, add the namespace, if necessary, to a vector of undefined extension namespaces, to be defined later.
    • registerExtension

      public void registerExtension(ExtensionNamespaceSupport extNsSpt)
      Register the extension namespace for an ElemExtensionDecl or ElemFunction, and prepare a support object to launch the appropriate ExtensionHandler at transformation runtime.
    • namespaceIndex

      public int namespaceIndex(String namespace, Vector extensions)
      Get the index for a namespace entry in the extension namespace Vector, -1 if no such entry yet exists.
    • getExtensions

      public Vector getExtensions()
      Get the vector of extension namespaces. Used to provide the extensions table access to a list of extension namespaces encountered during composition of a stylesheet.
    • registerUnregisteredNamespaces

      public void registerUnregisteredNamespaces()
      Attempt to register any unregistered extension namespaces.
    • defineJavaNamespace

      public ExtensionNamespaceSupport defineJavaNamespace(String ns)
      For any extension namespace that is not either predefined or defined by a "component" declaration or exslt function declaration, attempt to create an ExtensionNamespaceSuport object for the appropriate Java class or Java package Extension Handler. Called by StylesheetRoot.recompose(), after all ElemTemplate compose() operations have taken place, in order to set up handlers for the remaining extension namespaces.
      Parameters:
      ns - The extension namespace URI.
      Returns:
      An ExtensionNamespaceSupport object for this namespace (which defines the ExtensionHandler to be used), or null if such an object cannot be created.
      Throws:
      TransformerException
