Extension
abstract class Extension (View source)
Add extension that can be added to an object with {@link Object::add_extension()}.
For {@link DataObject} extensions, use {@link DataExtension}. Each extension instance has an "owner" instance, accessible through {@link getOwner()}. Every object instance gets its own set of extension instances, meaning you can set parameters specific to the "owner instance" in new Extension instances.
