DB_NestedSet::getChildren — Fetch the children _one level_ after of a node given by id
DB_NestedSet::getParent — Fetch the immediate parent of a node given by id
DB_NestedSet::getParents — Fetch the parents of a node given by id
DB_NestedSet::getRootNodes — Fetches the first level (the rootnodes) of the NestedSet

DB_NestedSet::isParent — See if a given node is a parent of another given node
DB_NestedSet::moveTree — Wrapper for node moving and copying
DB_NestedSet::pickNode — Fetch the data of a node with the given id
DB_NestedSet::removeListener — Removes an event listener
DB_NestedSet::setAttr — Sets an object attribute
DB_NestedSet::setDbOption — Sets a db option. Example, setting the sequence table format
DB_NestedSet::setsortMode — This enables you to set specific options for each output method
DB_NestedSet::testLock — Tests if a database lock is set
DB_NestedSet::triggerEvent — Triggers and event an calls the event listeners
DB_NestedSet::updateNode — Changes the payload of a node
