Method Details

fromEventSourced

public static <Command,
Event,
State>
PersistenceProbeBehavior<Command,Event,State> fromEventSourced(Behavior<Command> behavior,
 State initialState,
 long initialSequenceNr)

Given an EventSourcedBehavior, produce a non-persistent Behavior which synchronously publishes events and snapshots for inspection. State is updated as in the EventSourcedBehavior, and side effects are performed synchronously. The resulting Behavior is, contingent on the command handling, event handling, and side effects being compatible with the BehaviorTestKit, testable with the BehaviorTestKit.

The returned Behavior does not intrinsically depend on configuration: it therefore does not serialize and assumes an unbounded stash for commands.

Parameters:

behavior - a (possibly wrapped) EventSourcedBehavior to serve as the basis for the persistenceProbe behavior

initialState - start the persistenceProbe behavior with this state; if null, behavior's initialState will be used

initialSequenceNr - start the persistenceProbe behavior with this sequence number; only applies if initialState is non-null

Returns:

an PersistenceProbeBehavior based on an EventSourcedBehavior
