## org.jdom.output
Class XMLOutputter.NamespaceStack

    java.lang.Object
      org.jdom.output.XMLOutputter.NamespaceStack

Enclosing class:
  XMLOutputter

    protected class XMLOutputter.NamespaceStack

extends java.lang.Object

Our own null subclass of NamespaceStack. This plays a little trick with Java access protection. We want subclasses of XMLOutputter to be able to override protected methods that declare a NamespaceStack parameter, but we don't want to declare the parent NamespaceStack class as public.

Constructor Summary
`protected` | `XMLOutputter.NamespaceStack()`

Method Summary
`java.lang.String` | `getURI(java.lang.String prefix)` Given a prefix, this will return the namespace URI most rencently (topmost) associated with that prefix.
`java.lang.String` | `pop()` This will remove the topmost (most recently added) ``Namespace``, and return its prefix.
`void` | `push(Namespace ns)` This will add a new ``Namespace`` to those currently available.
`int` | `size()` This returns the number of available namespaces.
`java.lang.String` | `toString()` This will print out the size and current stack, from the most recently added ``Namespace`` to the "oldest," all to `System.out`.
