Interface Ownable

All Known Subinterfaces:

Component, Entity

public interface Ownable

An interface that designates something is ownable. Both entities and components can be ownable. This can be used to create hierarchies of components. As an example, a ParticleSystem component might own the Geometry component that a task prepares for it.

The Ownable interface is the main entry-point for programmers to manage their inter-entity/component relationships, and not Owner. The Owner interface exists so that Ownable implementations can notify owners of changes.
