Catalyst::Controller::DBIC::API::JoinBuilder - Provides a helper class to automatically keep track of joins in complex searches

version 2.003002

JoinBuilder is used to keep track of joins automgically for complex searches. It accomplishes this by building a simple tree of parents and children and then recursively drilling into the tree to produce a useable join attribute for ->search.

parent stores the direct ascendant in the datastructure that represents the join

children stores the immediate descendants in the datastructure that represents the join.

Handles the following methods:

    all_children => 'elements'
    has_children => 'count'
    add_child => 'push'

joins holds the cached generated join datastructure.

Sets the key for this level in the generated hash

_build_joins finds the top parent in the structure and then recursively iterates the children building out the join datastructure
