Package ptree :: Module elements :: Class _MultiParentedElement

classobj _MultiParentedElement

A specialized version of etree.ElementTree.Element that keeps track of a list of parent pointers for each element.

Each _ParentedElement may have zero or more parents. In particular, subtrees may be shared. If a single _MultiParentedElement is used as multiple children of the same parent, then that parent will appear multiple times in the parents list.

_MultiParentedElements should never be used in the same tree as other Element implementation classes. Mixing Element implementations may result in incorrect parent pointers and in ValueError exceptions.
