orrery.models.GlobalModelRegistry#

class GlobalModelRegistry[source]#

Bases: ModelRegistry

A ModelRegistry where Models can be added with an additional identifying prefix, allowing multiple Models of the same name to be added. An example use might be an application which has multiple windows open, where each window has its own set of Models (which might be stored in a ModelRegistry). The prefix allows you to distinguish Models for different windows while still maintaining a single global list of Models
