Registers a new node type or updates an existing node type using the specified definition and returns the resulting NodeType object.

Typically, the object passed to this method will be a NodeTypeTemplate (a subclass of NodeTypeDefinition) acquired from NodeTypeManager.createNodeTypeTemplate and then filled-in with definition information.

Parameters:

ntd - an NodeTypeDefinition.

allowUpdate - a boolean

Returns:

the registered node type

Throws:

InvalidNodeTypeDefinitionException - if the NodeTypeDefinition is invalid.

NodeTypeExistsException - if allowUpdate is false and the NodeTypeDefinition specifies a node type name that is already registered.

UnsupportedRepositoryOperationException - if this implementation does not support node type registration.

RepositoryException - if another error occurs.

registerNodeTypes

NodeTypeIterator registerNodeTypes(NodeTypeDefinition[] ntds,

                                   RepositoryException

Registers or updates the specified array of NodeTypeDefinition objects. This method is used to register or update a set of node types with mutual dependencies. Returns an iterator over the resulting NodeType objects.

The effect of the method is "all or nothing"; if an error occurs, no node types are registered or updated.

Parameters:

ntds - a collection of NodeTypeDefinitions

allowUpdate - a boolean

Returns:

the registered node types.

Throws:

InvalidNodeTypeDefinitionException - if a NodeTypeDefinition within the Collection is invalid or if the Collection contains an object of a type other than NodeTypeDefinition.

NodeTypeExistsException - if allowUpdate is false and a NodeTypeDefinition within the Collection specifies a node type name that is already registered.

UnsupportedRepositoryOperationException - if this implementation does not support node type registration.

RepositoryException - if another error occurs.

                        NoSuchNodeTypeException,
                        RepositoryException

Unregisters the specified node type.

Parameters:

name - a String.

Throws:

UnsupportedRepositoryOperationException - if this implementation does not support node type registration.

NoSuchNodeTypeException - if no registered node type exists with the specified name.

RepositoryException - if another error occurs.

JCR 2.0

unregisterNodeTypes

void unregisterNodeTypes(String[] names)
                  throws UnsupportedRepositoryOperationException,

                         RepositoryException

Unregisters the specified set of node types. Used to unregister a set of node types with mutual dependencies.

Parameters:

names - a String array

Throws:

UnsupportedRepositoryOperationException - if this implementation does not support node type registration.

NoSuchNodeTypeException - if one of the names listed is not a registered node type.

RepositoryException - if another error occurs.
