/**
 * Remote version of the JCR {@link javax.jcr.nodetype.NodeType NodeType}
 * interface. Used by the
 * {@link org.apache.jackrabbit.rmi.server.ServerNodeType ServerNodeType} and
 * {@link org.apache.jackrabbit.rmi.client.ClientNodeType ClientNodeType}
 * adapters to provide transparent RMI access to remote node types.
 * <p>
 * The methods in this interface are documented only with a reference
 * to a corresponding NodeType method. The remote object will simply forward
 * the method call to the underlying NodeType instance. Return values
 * and possible exceptions are copied over the network. Complex return
 * values (like NodeTypes and PropertyDefs) are retunred as remote
 * references to the corresponding remote interfaces. RMI errors are
 * signalled with RemoteExceptions.
