// meant for use mixed-in to a Route file

// When a route is deactivated, this mixin clears the Ember Data store of
|
|
// models of type specified by the required param `modelType`.
|
|
//
|
|
// example:
|
|
// Using this as with a modelType of `datacenter` on the infrastructure
|
|
// route will cause all `datacenter` models to get unloaded when the
|
|
// infrastructure route is navigated away from.
