1 | NAME |
| 2 | DBIx::Class::Tree - Manipulate and anaylze tree structured data. |
| 609f3762 |
3 | |
| 4 | DESCRIPTION |
| 5 | The tree modules provide the tools to represent, modify, and analyze |
| 6 | trees of data with DBIx::Class. |
| 7 | |
| 8 | COMPONENTS |
| 9 | DBIx::Class::Tree::AdjacencyList - Manage a tree of data using the |
| af9120b0 |
10 | common adjacency list model. |
| 609f3762 |
11 | |
| 12 | DBIx::Class::Tree::AdjacencyList::Ordered - Glue DBIx::Class::Ordered |
| af9120b0 |
13 | and DBIx::Class::Tree::AdjacencyList together. |

| 15 | DAG |
| 16 | All tree related modules must conform to have and use the basic |
| 17 | traversal methods of a DAG. For the most part this just means that Tree |
| 18 | modules must provide the appearance of having multiple parents per node |
| 19 | (via a parents() method) but may very well never return more than one |
| 20 | parent. All utility modules, such as a Visitor module, should do its |
| 21 | best to never assume that a node only has one parent. There are |
| 22 | situations where this is not possible - in those cases the module's |
| 23 | documentation should clearly state that it is not compatible with DAGs. |
| 24 | |
| 25 | So far there is no Tree::DAG module, but there will be. These |
| 26 | requirements are vague, and the requirements of Tree modules to be DAG |
| 27 | compatible will become more defined in due course. |
