Public Member Functions

 ilValidator ($a_log=false)
 Constructor.
 getPossibleModes ()
 get possible ilValidator modes public
 setMode ($a_mode, $a_value)
 set mode of ilValidator Usage: setMode("restore",true) => enable object restorey setMode("all",true) => enable all features For all possible modes see variables declaration
 isModeEnabled ($a_mode)
 Is a particular mode enabled?
 isLogEnabled ()
 setModeDependencies ()
 Sets modes by considering mode dependencies; some modes require other modes to be activated.
 validate ()
 Performs the validation for each enabled mode.
 findMissingObjects ()
 Search database for all object entries with missing reference and/or tree entry and stores result in $this->missing_objects.
 findInvalidRolefolders ()
 Search database for all rolefolder object entries with missing reference entry.
 findInvalidRBACEntries ()
 Search database for all role entries that are linked to invalid ref_ids.
 getMissingObjects ()
 Gets all object entries with missing reference and/or tree entry.
 findInvalidReferences ()
 Search database for all reference entries that are not linked with a valid object id and stores result in $this->invalid_references.
 getInvalidReferences ()
 Gets all reference entries that are not linked with a valid object id.
 findInvalidChilds ()
 Search database for all tree entries without any link to a valid object and stores result in $this->invalid_childs.
 getInvalidChilds ()
 Gets all tree entries without any link to a valid object.
 findUnboundObjects ()
 Search database for all tree entries having no valid parent (=> no valid path to root node) and stores result in $this->unbound_objects Result does not contain childs that are marked as deleted! Deleted childs have a negative number.
 findDeletedObjects ()
 Search database for all tree entries having no valid parent (=> no valid path to root node) and stores result in $this->unbound_objects Result also contains childs that are marked as deleted! Deleted childs has a negative number in ["deleted"] otherwise NULL.
 getUnboundObjects ()
 Gets all tree entries having no valid parent (=> no valid path to root node) Returns an array with child => actual entry with broken uplink to its parent parent => parent of child that does not exist grandparent => grandparent of child (where path to root node continues) deleted => containing a negative number (= parent in trash) or NULL (parent does not exist at all)
 getDeletedObjects ()
 Gets all object in trash.
 getInvalidRolefolders ()
 Gets invalid rolefolders (same as missing objects)
 removeInvalidReferences ($a_invalid_refs=NULL)

 Restores missing reference and/or tree entry for all objects found by this::getMissingObjects() Restored object are placed in RecoveryFolder.
 restoreReference ($a_obj_id)
 restore a reference for an object Creates a new reference entry in DB table object_reference for $a_obj_id
 restoreUnboundObjects ($a_unbound_objects=NULL)
 Restore objects (and their subobjects) to RecoveryFolder that are valid but not linked correctly in the hierarchy because they point to an invalid parent_id.
 restoreTrash ($a_deleted_objects=NULL)
 Restore all objects in trash to RecoveryFolder NOTE: All objects will be restored to top of RecoveryFolder regardless of existing hierarchical structure!

 purgeObjects ($a_nodes)
 removes objects from system
 initGapsInTree ()
 Initializes gaps in lft/rgt values of a tree.
 handleErr ($error)
 Callback function handles PEAR_error and outputs detailed infos about error TODO: implement that in global errorhandler of ILIAS (via templates)
 writeScanLogArray ($a_arr)
 writeScanLogLine ($a_msg)
 hasScanLog ()
 Quickly determine if there is a scan log.

- Public Member Functions inherited from PEAR
 PEAR ($error_class=null)
 Constructor.
 _PEAR ()
 Destructor (the emulated type of...).
& getStaticProperty ($class, $var)
 If you have a class that's mostly/entirely static, and you need static properties, you can use this method to simulate them.
 registerShutdownFunc ($func, $args=array())
 Use this function to register a shutdown method for static classes.
 isError ($data, $code=null)
 Tell whether a value is a PEAR error.
 setErrorHandling ($mode=null, $options=null)
 Sets how errors generated by this object should be handled.
 expectError ($code= '*')
 This method is used to tell which errors you expect to get.
 popExpect ()
 This method pops one element off the expected error codes stack.
 _checkDelExpect ($error_code)
 This method checks unsets an error code if available.
 delExpect ($error_code)
 This method deletes all occurences of the specified element from the expected error codes stack.
& raiseError ($message=null, $code=null, $mode=null, $options=null, $userinfo=null, $error_class=null, $skipmsg=false)
 This method is a wrapper that returns an instance of the configured error class with this object's default error handling applied.
& throwError ($message=null, $code=null, $userinfo=null)
 Simpler form of raiseError with fewer options.
 staticPushErrorHandling ($mode, $options=null)
