Class PrefixForUriEnumerator

java.lang.Object
  org.apache.xml.utils.PrefixForUriEnumerator

All Implemented Interfaces:

Enumeration

class PrefixForUriEnumerator

extends Object

implements Enumeration

Implementation of Enumeration filter, wrapped aroung the get-all-prefixes version of the operation. This is NOT necessarily the most efficient approach; finding the URI and then asking what prefixes apply to it might make much more sense.
