Method Summary

void	add(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN normName, javax.naming.directory.Attributes entry) In the pre-invocation state this interceptor method checks to see if the entry to be added already exists.
void	delete(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN name) Checks to make sure the entry being deleted exists, and has no children, otherwise throws the appropriate LdapException.
void	destroy() This method does nothing by default.
void	init(DirectoryServiceConfiguration factoryCfg, InterceptorConfiguration cfg) This method does nothing by default.
javax.naming.NamingEnumeration	list(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN baseName) Checks to see the base being searched exists, otherwise throws the appropriate LdapException.
javax.naming.directory.Attributes	lookup(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN name) Checks to make sure the entry being looked up exists other wise throws the appropriate LdapException.
javax.naming.directory.Attributes	lookup(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN name, java.lang.String[] attrIds) Checks to see the base being searched exists, otherwise throws the appropriate LdapException.
void	modify(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN name, int modOp, javax.naming.directory.Attributes attrs) Checks to see the entry being modified exists, otherwise throws the appropriate LdapException.

void	modifyRn(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN dn, java.lang.String newRn, boolean deleteOldRn) Checks to see the entry being renamed exists, otherwise throws the appropriate LdapException.
void	move(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN oriChildName, org.apache.directory.shared.ldap.name.LdapDN newParentName) Checks to see the entry being moved exists, and so does its parent, otherwise throws the appropriate LdapException.
void	move(NextInterceptor nextInterceptor, org.apache.directory.shared.ldap.name.LdapDN oriChildName, org.apache.directory.shared.ldap.name.LdapDN newParentName, java.lang.String newRn, boolean deleteOldRn) Checks to see the entry being moved exists, and so does its parent, otherwise throws the appropriate LdapException.
