Overview

Base Composite model class, used for extending views for any child of Tempo::Model::Composite Inherits the id, and type from ViewRecords::Model, and adds an integer depth to hold the depth within the tree structure of the Composite model. It is important to note, the ViewRecord has no way of determining the depth of the model it represents, and this must be supplied to the instance on instantiation, or after.

The Composite ViewRecord class also keeps track of the max depth of all of it’s members, this can be used to calculate the padding added to any views.

The Composite View Model is an abstract model that is extended to create views for children of the Composite Model class. See ViewRecords::Project for an example.
