class experimentor.models.meta.MetaModel(name, bases, attrs)

Meta Model type which will be responsible for keeping track of all the created models in the program. This is very useful for things like automatically building a GUI, initializing/finishing all the devices, etc. and also to perform checks at the beginning of the runtime, by doing introspection on all the defined models, regardless of whether they are instantiated later on or no.

One of the tasks is to generate a list of signals available in each model. Signals are specified as class attributes and therefore they can be accounted for before instantiating the class. Once the class is being instantiated, each object will re-instantiate the signals in order to keep its own copy, and establishing the proper owner of the signal.

get_instances(recursive=False)

Get all instances of this class in the registry.

Parameters:recursive (bool) – Search for instances recursively through inherited objects

get_models(recursive=False)

Gets all the models which share the MetaModel origin.

Parameters:recursive (bool) – Search recurisvely in sub classes of the model
