PHP Interface izzum\statemachine\loader\Loader
Loader is a marker interface for our package, so it always expects a Loader
implementation.
An implementation of Loader might use subclasses of Transition and State to
provide alternative behaviour eg: an application performance optimized
prioritized transition, so that when a state has 2 outgoing transitions,
1 is always tried first.
An implementation of Loader knows how to retrieve the transition and state
data from it's source and it knows about the izzum\statemachine. Therefore,
the Loader implementation is best suited to create all transitions and
states.
A Loader implementation might create application specific subclasses of
Transition and State (in case you need extra functionality)
Ideally your specific loader should:
- implement this interface: for use in a subclass of AbstractFactory
- create the transitions and states correctly (use LoaderArray via composition)
- work together with your persistence adapter (a concrete persistence adapter
could implement this interface) to retrieve the data for the creation of the
transitions and states
- act as a Decorator for the LoaderArray
