Class NodeTypeCache

java.lang.Object
  org.apache.jackrabbit.jcr2spi.nodetype.NodeTypeCache

public class NodeTypeCache
extends Object

NodeTypeCache implements a cache for QNodeTypeDefinitions on a userId basis.

Method Summary

Iterator<QNodeTypeDefinition>	getAllDefinitions(NodeTypeStorage storage) Returns an Iterator over all node type definitions registered.
Iterator<QNodeTypeDefinition>	getDefinitions(NodeTypeStorage storage, Name[] nodeTypeNames) Returns the QNodeTypeDefinitions for the given node type names.
static NodeTypeCache	getInstance(RepositoryService service, String userId)
void	registerNodeTypes(NodeTypeStorage storage, QNodeTypeDefinition[] nodeTypeDefs, boolean allowUpdate)
void	unregisterNodeTypes(NodeTypeStorage storage, Name[] nodeTypeNames)
NodeTypeStorage	wrap(NodeTypeStorage storage) Wraps this NodeTypeCache around the passed storage and exposes itself again as a NodeTypeStorage.

Method Detail

getInstance

public static NodeTypeCache getInstance(RepositoryService service,
                                        String userId)

Parameters:

service - the repository service.

userId - the userId. If null this method will return a new cache instance for each such call.

Returns:

the NodeTypeCache instance for the given service and userId.

getAllDefinitions

public Iterator<QNodeTypeDefinition> getAllDefinitions(NodeTypeStorage storage)
                                                throws RepositoryException

Returns an Iterator over all node type definitions registered.

Returns:

Throws:

RepositoryException

getDefinitions

public Iterator<QNodeTypeDefinition> getDefinitions(NodeTypeStorage storage,
                                                    Name[] nodeTypeNames)
                                             throws NoSuchNodeTypeException,
                                                    RepositoryException

Returns the QNodeTypeDefinitions for the given node type names. The implementation is free to return additional definitions e.g. dependencies.

Parameters:

nodeTypeNames -

Returns:

Throws:

NoSuchNodeTypeException

RepositoryException

registerNodeTypes

public void registerNodeTypes(NodeTypeStorage storage,
                              QNodeTypeDefinition[] nodeTypeDefs,
                              boolean allowUpdate)
                       throws RepositoryException

Throws:

RepositoryException

unregisterNodeTypes

public void unregisterNodeTypes(NodeTypeStorage storage,
                                Name[] nodeTypeNames)
                         throws NoSuchNodeTypeException,
                                RepositoryException

Throws:

NoSuchNodeTypeException

RepositoryException

wrap

public NodeTypeStorage wrap(NodeTypeStorage storage)

Wraps this NodeTypeCache around the passed storage and exposes itself again as a NodeTypeStorage.

Parameters:

storage - the node type storage to wrap.

Returns:

node type storage instance using this cache.
