Object

com.lightbend.lagom.javadsl.persistence.PersistentEntity.Behavior

All Implemented Interfaces:

Serializable, scala.Equals, scala.Product

Enclosing class:

PersistentEntity<Command,Event,State>

public class PersistentEntity.Behavior
extends Object
implements scala.Product, scala.Serializable

Behavior consists of current state and functions to process incoming commands and persisted events. Behavior is an immutable class. Use the mutable PersistentEntity.BehaviorBuilder for defining command and event handlers.

Behavior

public Behavior(State state,
                scala.collection.immutable.Map<Class<? extends Event>,Function<? extends Event,PersistentEntity.Behavior>> eventHandlers,
                scala.collection.immutable.Map<Class<? extends Command>,BiFunction<? extends Command,PersistentEntity.CommandContext<Object>,PersistentEntity.Persist<? extends Event>>> commandHandlers)

Method Detail

state

public State state()

eventHandlers

public scala.collection.immutable.Map<Class<? extends Event>,Function<? extends Event,PersistentEntity.Behavior>> eventHandlers()

commandHandlers

public scala.collection.immutable.Map<Class<? extends Command>,BiFunction<? extends Command,PersistentEntity.CommandContext<Object>,PersistentEntity.Persist<? extends Event>>> commandHandlers()

withState

public PersistentEntity.Behavior withState(State newState)

Returns:

new instance with the given state

builder

public PersistentEntity.BehaviorBuilder builder()

Create a BehaviorBuilder that corresponds to this Behavior, i.e. the builder is populated with same state, same event and command handler functions.
