MetaFactory

Added in version 1.28.

class MetaFactory(**properties: Any)

Superclasses: PluginFeature, Object, InitiallyUnowned, Object

Register a MetaInfo that can be automatically loaded the first time it is used.

In general, applications and plugins don’t need to use the factory beyond registering the meta in a plugin init function. Once that is done, the meta is stored in the registry, and ready as soon as the registry is loaded.
