This component provides a light weight, multi-tenant Marking Store for use with symfony/workflow.

• Implements symfony/workflow MarkingStoreInterface as a shim between a Workflow and it's marking store.
• A UUID is stored on a subject, instead of the subject's marking.
  • The property used to access a subject's uuid must not be marking. This property name is reserved by symfony/workflow. Its use will throw an exception.
• The shim communicates with a marking store through a mediator.
• The shim transforms between a Marking and an array-of-places (used by the mediator and marking store) as needed.
• The mediator is responsible for accessing the actual marking store.
• The current mediator dispatches events to get and set an array-of-places on a marking store.
  • This implementation has a known issue, where the shim can get or set a marking, not knowning there are no marking stores listening. Any marking's set, would not be persisted.

Mediator event's include three identifiers from the shim.

• The shim's name will become $storeName.
• The subject's UUID will become $subjectUuid.
• The property used to store the UUID on a subject will become $property.

The InMemoryMarkings marking store persists markings in an array, where a marking's identifiers form the key and the *array-of-places" the value.

$storeName>/$subjectUuid>/$property = [place1, place2, ...]

The mediator dispatches a MarkingStoreEvent to active listeners of four events.

• workflow.store.created is dispatched during construction of the shim.
• workflow.places.get is dispatched to get an array-of-places.
• workflow.places.setting is dispatched to set an array-of-places.
• workflow.places.set is dispatched after the array-of-places has be set. Listeners can perform cleanup code during this event (for instance, flushing a Doctrine entity).
