Methods
This class inherits the methods of NamespaceContext (JavaScript). Other methods are in addition.
Usage
The name and prefix form a namespace. The namespace is added if the prefix does not already exist in the namespace context. If the prefix already exists, this namespace replaces the existing namespace.Examples
This buttononclick event
creates a namespace context if it does not yet exist then adds or
replaces a namespace. The prefix and URI for the namespace are global
objects defined elsewhere on the page before the button is clicked.
The namespace context is a global object so other code can use it.if(sessionScope.ns == null) {
sessionScope.ns = new NamespaceContextImpl();
}
sessionScope.ns.addNamespace(
requestScope.prefix, requestScope.uri);
