oracle.jcr.nodetype

Interface OracleNodeTypeManager

All Superinterfaces:

NodeTypeManager

public interface OracleNodeTypeManager
extends NodeTypeManager

OracleNodeTypeManager allows discovery of JCR node types.

For the XML DB Content Connector, OracleNodeTypeManager also allows XML schemas to be registered for use in JCR. Doing so creates JCR node types corresponding to the schema types and global element declarations defined by the XML schema. Schema-based content and metadata will then be exposed as JCR nodes of these node types, instead of the nt:unstructured node type.

Before a schema is registered for use in JCR, it should be registered for use in the database using the DBMS_XMLSCHEMA.registerschema PL/SQL procedure. Only globally-registered schemas can be used in JCR.

The list of registered XML schemas is cached by the OracleNodeTypeManager object. The cache is automatically refreshed each time registerXMLSchema or unregisterXMLSchema is called on the OracleNodeTypeManager object. Call refresh to explicitly refresh the cache.

Refer to XDBRepositoryConfiguration for further information on how the list of registered XML schemas is stored by the XML DB Content Connector.

Method Detail

refresh

void refresh()
      throws RepositoryException

Invalidates the in-memory copy of the node type registry and reloads it from the content repository.

Throws:

RepositoryException - if the operation fails

registerXMLSchema

void registerXMLSchema(java.lang.String schemaLocation,
                       java.lang.String jcrNodeTypeNamespace)
                throws AccessDeniedException,
                       RepositoryException

Registers the XML Schema having the specified schema location URL.

If the schema is already registered, the JCR node type namespace is updated to the value specified.

Parameters:

schemaLocation - the schema location; required

jcrNodeTypeNamespace - the namespace into which to create JCR node types, or null to use the target namespace of the schema

Throws:

AccessDeniedException - if the session does not have sufficient privileges to perform the operation

RepositoryException - if the operation otherwise fails

unregisterXMLSchema

void unregisterXMLSchema(java.lang.String schemaLocation)
                  throws AccessDeniedException,
                         RepositoryException

Unregisters the XML Schema having the specified schema location URL.

Parameters:

schemaLocation - the schema location; required

Throws:

AccessDeniedException - if the session does not have sufficient privileges to perform the operation

RepositoryException - if the operation otherwise fails
