JCR 1.0: 6.7.9 Discovering available Node Types (Content Repository for Java Technology API)

6.7.9 Discovering available Node Types

Discovery of which node types are available in a content repository is done through the NodeTypeManager object, which is acquired via the Workspace. Recall from earlier in the specification:

javax.jcr.
Workspace

NodeTypeManager

getNodeTypeManager()

Returns the NodeTypeManager object through which available node types are discovered. There is one node type registry per repository, therefore the NodeTypeManager is not workspace-specific; it provides introspection methods for the global, repository-wide set of available node types.

A RepositoryException is thrown if an error occurs.

The NodeTypeManager provides the following methods:

javax.jcr.nodetype. NodeTypeManager
NodeType	getNodeType(String nodeTypeName) Returns the NodeType specified by nodeTypeName. If no node type by that name is registered, a NoSuchNodeTypeException is thrown. A RepositoryException is thrown if another error occurs.
NodeType Iterator	getAllNodeTypes() Returns all available node types, primary and mixin. A RepositoryException is thrown if an error occurs.
NodeType Iterator	getPrimaryNodeTypes() Returns all available primary node types. A RepositoryException is thrown if an error occurs.
NodeType Iterator	getMixinNodeTypes() Returns all available mixin types. If none are available, an empty iterator is returned. A RepositoryException is thrown if an error occurs.
