Session

void

setNamespacePrefix(String prefix, String uri)

Within the scope of this Session, remaps a persistently registered namespace URI to the new prefix. The remapping only affects operations done through this session. To clear all remappings, the client must acquire a new Session.

A prefix that is currently already mapped to some URI (either persistently in the repository NamespaceRegistry or transiently within this Session) cannot be remapped to a new URI using this method, since this would make any content stored using the old URI unreadable. An attempt to do this will throw a NamespaceException.

As well, a NamespaceException will be thrown if an attempt is made to remap an existing namespace URI to a prefix beginning with the characters “xml” (in any combination of case).

A NamespaceException will also be thrown if the specified uri is not among those registered in the NamespaceRegistry.

A RepositoryException is thrown if another error occurs.
