Class ExtensionNamespacesManager
public class ExtensionNamespacesManager
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
.
ExtensionNamespacesManager() - An ExtensionNamespacesManager is instantiated the first time an extension function or
element is found in the stylesheet.
|
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.
|
ExtensionNamespaceSupport | defineJavaNamespace(String ns, String classOrPackage)
|
Vector | getExtensions() - Get the vector of extension namespaces.
|
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.
|
void | registerExtension(String namespace) - If necessary, register the extension namespace found compiling a function or
creating an extension element.
|
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.
|
void | registerUnregisteredNamespaces() - Attempt to register any unregistered extension namespaces.

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.
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.
ns
- The extension namespace URI.
- An ExtensionNamespaceSupport object for this namespace
(which defines the ExtensionHandler to be used), or null if such
an object cannot be created.
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.
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.
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.
registerUnregisteredNamespaces
public void registerUnregisteredNamespaces()
Attempt to register any unregistered extension namespaces.
