trait WriteEventAdapter extends AnyRef
Facility to convert to specialised data models, as may be required by specialized persistence Journals.
Typical use cases include (but are not limited to):
- adding metadata, a.k.a. "tagging" - by wrapping objects into tagged counterparts
- manually converting to the Journals storage format, such as JSON, BSON or any specialised binary format
- splitting up large events into sequences of smaller ones

def
toJournal(event: Any): Any
Convert domain event to journal event type.
Convert domain event to journal event type.
Some journal may require a specific type to be returned to them, for example if a primary key has to be associated with each event then a journal may require adapters to return
com.example.myjournal.EventWithPrimaryKey(event, key)
.The
toJournal
adaptation must be an 1-to-1 transformation. It is not allowed to drop incoming events during thetoJournal
adaptation.- event
the application-side domain event to be adapted to the journal model
- returns
the adapted event object, possibly the same object if no adaptation was performed
