Configurable object graph traversal library for BreezeJs including client-side cascading delete & deep copy.
Cascade.js uses the pattern of principle-dependent relationships between an entity and its properties for traversing the object graph. The dependent of a relationship holds a foreign key to the principle. When the cascade function is called on an entity, it first executes the pre callback before to visiting any of the entity's dependent properties. The cascade function is then recursively called on each entity in its dependent properties. After every dependent has been visited, the post callback is executed.
However, object graphs often do not have a tree-like structure and contain cycles, or certain entities may require different pre- & post-traversal behavior. Therefore, the cascade function takes in a configuration object that allows the user to override the traversal of specific dependent properties, either to ignore and not recursively call cascade on it or to execute different behavior all together. In additon, each entity type may specify its own pre & post callbacks that will be excuted in place of the default action.
