public interface Active

Active is the root of the all interfaces related to the activity of an active object. It is a convenience for having a common interface that can be used to type objects implementing one or more of the others.

So far we considered three steps in the lifecycle of an active object.

• the initialization of the activity (done only once)
• the activity itself
• the end of the activity (unique event)

In case of a migration, an active object stops and restarts its activity automatically without invoking the init or ending phases. Only the activity itself is restarted.
