      PersistenceId apply​(java.lang.String entityTypeHint, java.lang.String entityId)
      Constructs a PersistenceId from the given entityTypeHint and entityId by concatenating them with | separator.
      PersistenceId apply​(java.lang.String entityTypeHint, java.lang.String entityId, java.lang.String separator)
      Constructs a PersistenceId from the given entityTypeHint and entityId by concatenating them with the separator.
      java.lang.String DefaultSeparator()
      Default separator character used for concatenating a typeHint with entityId to construct unique persistenceId.

      • DefaultSeparator

        public java.lang.String DefaultSeparator()
        Default separator character used for concatenating a typeHint with entityId to construct unique persistenceId. This must be same as in Lagom's scaladsl.PersistentEntity, for compatibility. No separator is used in Lagom's javadsl.PersistentEntity so for compatibility with that the "" separator must be used instead.
      • apply

        public PersistenceId apply​(java.lang.String entityTypeHint,
                                   java.lang.String entityId)
        Constructs a PersistenceId from the given entityTypeHint and entityId by concatenating them with | separator.

        Cluster Sharding is often used together with EventSourcedBehavior for the entities. The PersistenceId of the EventSourcedBehavior can typically be constructed with:

        
         PersistenceId(entityContext.entityTypeKey.name, entityContext.entityId)
         

        That format of the PersistenceId is not mandatory and only provided as a convenience of a "standardized" format.

        Another separator can be defined by using the apply that takes a separator parameter.

        The | separator is also used in Lagom's scaladsl.PersistentEntity but no separator is used in Lagom's javadsl.PersistentEntity. For compatibility with Lagom's javadsl.PersistentEntity you should use "" as the separator.

        Throws:
        java.lang.IllegalArgumentException - if the entityTypeHint or entityId contains |
      • apply

        public PersistenceId apply​(java.lang.String entityTypeHint,
                                   java.lang.String entityId,
                                   java.lang.String separator)
        Constructs a PersistenceId from the given entityTypeHint and entityId by concatenating them with the separator.

        Cluster Sharding is often used together with EventSourcedBehavior for the entities. The PersistenceId of the EventSourcedBehavior can typically be constructed with:

        
         PersistenceId(entityContext.entityTypeKey.name, entityContext.entityId)
         

        That format of the PersistenceId is not mandatory and only provided as a convenience of a "standardized" format.

        The default separator | is used by the apply that doesn't take a separator parameter.

        The | separator is also used in Lagom's scaladsl.PersistentEntity but no separator is used in Lagom's javadsl.PersistentEntity. For compatibility with Lagom's javadsl.PersistentEntity you should use "" as the separator.

        Throws:
        java.lang.IllegalArgumentException - if the entityTypeHint or entityId contains separator
      • of

        public PersistenceId of​(java.lang.String entityTypeHint,
                                java.lang.String entityId)
        Constructs a PersistenceId from the given entityTypeHint and entityId by concatenating them with | separator.

        Cluster Sharding is often used together with EventSourcedBehavior for the entities. The PersistenceId of the EventSourcedBehavior can typically be constructed with:

        
         PersistenceId.of(entityContext.getEntityTypeKey().name(), entityContext.getEntityId())
         

        That format of the PersistenceId is not mandatory and only provided as a convenience of a "standardized" format.

        Another separator can be defined by using the PersistenceId.of that takes a separator parameter.

        The | separator is also used in Lagom's scaladsl.PersistentEntity but no separator is used in Lagom's javadsl.PersistentEntity. For compatibility with Lagom's javadsl.PersistentEntity you should use "" as the separator.

                                java.lang.String separator)
        Constructs a PersistenceId from the given entityTypeHint and entityId by concatenating them with the separator.

        Cluster Sharding is often used together with EventSourcedBehavior for the entities. The PersistenceId of the EventSourcedBehavior can typically be constructed with:

        public PersistenceId ofUniqueId​(java.lang.String id)
        Constructs a PersistenceId with id as the full unique identifier.
