fromJournal

public EventSeq fromJournal(java.lang.Object event,
                            java.lang.String manifest)

Description copied from interface: ReadEventAdapter

Convert a event from its journal model to the applications domain model.

One event may be adapter into multiple (or none) events which should be delivered to the PersistentActor. Use the specialised EventSeq.single(java.lang.Object) method to emit exactly one event, or EventSeq.empty() in case the adapter is not handling this event. Multiple EventAdapter instances are applied in order as defined in configuration and their emitted event seqs are concatenated and delivered in order to the PersistentActor.

Specified by:

fromJournal in interface ReadEventAdapter

Parameters:

event - event to be adapted before delivering to the PersistentActor

manifest - optionally provided manifest (type hint) in case the Adapter has stored one for this event, "" if none

Returns:

sequence containing the adapted events (possibly zero) which will be delivered to the PersistentActor

manifest

public java.lang.String manifest(java.lang.Object event)

Description copied from interface: WriteEventAdapter

Return the manifest (type hint) that will be provided in the fromJournal method. Use "" if manifest is not needed.

Specified by:

manifest in interface WriteEventAdapter

toJournal

public java.lang.Object toJournal(java.lang.Object event)

Description copied from interface: WriteEventAdapter

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.

Specified by:

toJournal in interface WriteEventAdapter

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
