The node interface, for inserting and manipulating nodes within the tree, is accessed on a record level. A full implementation of this interface will be as follows:
<code type="php">
interface Doctrine_Node_Interface {
/**
* insert node into tree
*/
public function insertAsParentOf(Doctrine_Record $dest);
public function insertAsPrevSiblingOf(Doctrine_Record $dest);
public function insertAsNextSiblingOf(Doctrine_Record $dest);
public function insertAsFirstChildOf(Doctrine_Record $dest);
public function insertAsLastChildOf(Doctrine_Record $dest);
public function addChild(Doctrine_Record $record);
/**
* moves node (if has children, moves branch)
*
*/
public function moveAsPrevSiblingOf(Doctrine_Record $dest);
public function moveAsNextSiblingOf(Doctrine_Record $dest);
public function moveAsFirstChildOf(Doctrine_Record $dest);
public function moveAsLastChildOf(Doctrine_Record $dest);
/**
* node information
*/
public function getPrevSibling();
public function getNextSibling();
public function getSiblings($includeNode = false);
public function getFirstChild();
public function getLastChild();
public function getChildren();
public function getDescendants();
public function getParent();
public function getAncestors();
public function getPath($seperator = ' > ', $includeNode = false);
public function getLevel();
public function getNumberChildren();
public function getNumberDescendants();
/**
* node checks
*/
public function hasPrevSibling();
public function hasNextSibling();
public function hasChildren();
public function hasParent();
public function isLeaf();
public function isRoot();
public function isEqualTo(Doctrine_Record $subj);
public function isDescendantOf(Doctrine_Record $subj);
public function isDescendantOfOrEqualTo(Doctrine_Record $subj);
public function isValidNode();
/**
* deletes node and it's descendants
*/
public function delete();
}
// if your model acts as tree you can retrieve the associated node object as follows
$record = $manager->getTable('Model')->find($pk);
$nodeObj = $record->getNode();
