Manual Reference Pages - DBIX::CLASS::TREE (3)
DBIx::Class::Tree - Manipulate and anaylze tree structured data.
The community can be found via:
The tree modules provide the tools to represent, modify, and analyze
trees of data with DBIx::Class.
DBIx::Class::Tree::AdjacencyList - Manage a tree of data using the
common adjacency list model.
DBIx::Class::Tree::AdjacencyList::Ordered - Glue DBIx::Class::Ordered
and DBIx::Class::Tree::AdjacencyList together.
All tree related modules must conform to have and use the basic traversal
methods of a DAG. For the most part this just means that Tree modules
must provide the appearance of having multiple parents per node (via a
parents() method) but may very well never return more than one parent.
All utility modules, such as a Visitor module, should do its best to
never assume that a node only has one parent. There are situations
where this is not possible - in those cases the modules documentation
should clearly state that it is not compatible with DAGs.
So far there is no Tree::DAG module, but there will be. These requirements
are vague, and the requirements of Tree modules to be DAG compatible will
become more defined in due course.
