```
  - toJournal
```
java.lang.Object toJournal(java.lang.Object event)
```
    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 the toJournal adaptation.
    
    Parameters:
    
    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
