Method Details

registerNamespace

public void registerNamespace(String prefix,
 String uri)
                       throws RepositoryException

Description copied from interface: NamespaceRegistry

Sets a one-to-one mapping between prefix and uri in the global namespace registry of this repository.

Assigning a new prefix to a URI that already exists in the namespace registry erases the old prefix. In general this can almost always be done, though an implementation is free to prevent particular remappings by throwing a NamespaceException.

On the other hand, taking a prefix that is already assigned to a URI and re-assigning it to a new URI in effect unregisters that URI. Therefore, the same restrictions apply to this operation as to NamespaceRegistry.unregisterNamespace.

Specified by:

registerNamespace in interface NamespaceRegistry

Overrides:

registerNamespace in class ReadOnlyNamespaceRegistry

Parameters:

prefix - The prefix to be mapped.

uri - The URI to be mapped.

Throws:

RepositoryException - if another error occurs.

unregisterNamespace

public void unregisterNamespace(String prefix)
                         throws RepositoryException

Description copied from interface: NamespaceRegistry

Removes a namespace mapping from the registry.

Specified by:

unregisterNamespace in interface NamespaceRegistry

Overrides:

unregisterNamespace in class ReadOnlyNamespaceRegistry

Parameters:

prefix - The prefix of the mapping to be removed.

Throws:

RepositoryException - if another error occurs.
