artemis-odb-2.0.0-RC6

Change Log

Version: 2.0.0-RC6 - 2016-08-09

• Fix: IntBag::get(index), ArrayIndexOutOfBoundsException reported size of backing array, not logical size.
• Fix: Possible IOOB exception when registering more than 64 systems.
• Fix: EntityLinkManager/LinkListener::onLinkKilled never fired for unestablished links.

Version: 2.0.0-RC5 - 2016-07-23

• BREAKING CHANGES
  • All usage of BitSet replaced by BitVector.
• BitVector: custom bitset implementation, generally faster than java.util.BitSet.
  • Optimized decoding of bits to integers, making all entity
    mutations more efficient.
  • unsafeGet, unsafeSet, unsafeClear require that the underlying
    array can contain the bit index.
  • BitVector::ensureCapacity(int bits) explicitly grows the bit vector.
    Typically used together with the unsafe- methods.
  • EntityManager::registerEntityStore(BitVector) - when representing
    entity id:s as bits, makes unsafe- methods safe - as the EntityManager
    grows the bit vector as necessary.
• Fix: Bag and IntBag equals method would return false for identical bags with different capacities.

Version: 2.0.0-RC4 - 2016-07-10

• BREAKING CHANGES
  • Removed previously deprecated code, see: 5de377d.
  • InvocationStrategy` - affectes custom implementations:
    • bag-of-systems now stored as a field, instead of being passed as a parameter
      to InvocationStrategy::process
    • InvocationStrategy::updateEntityStates must be called before processing the first system.
      Previously, the initial update was done by the world instance.
• ComponentManager::compositionIdentity(BitSet) now public.
• @AspectDescriptor now also valid on Archetypes.
• EntityLinkManager fires events for initial entities when registering a LinkListener;
  toggleable in constructor.

Version: 2.0.0-RC3 - 2016-06-21

• BREAKING CHANGES
  • World's systems array is now typed with BaseSystem; this should only have
    implication for custom implementations of SystemInvocationStrategy.
  • EntityFactory annotation processor and related classes have been removed,
    for more background, see #428.
• AspectFieldResolver; additional default injection field resolver
  • @AspectDescriptor on appropriate fields to inject
  • Valid targets: Aspect, Aspect.Builder, EntityTransmuter, EntitySubscription
• add EntityTransmuter(World, Aspect.Builder) constructor
• Deserialization exception reports on missing component identifiers (usually from
  manually edited json).
• Fix: WorldConfigurationBuilder.Priority didn't compare properly.
• Fix: thread safefty; InjectionCache's fields no longer static.

Version: 2.0.0-RC2 - 2016-05-26

• BREAKING CHANGES
  • Components require a public no-args constructor. While this was allowed in past versions,
    it never worked with serialization or pooled components.
• World#compositionId(entityId) added. Previously, one had to go
  via Entity#getCompositionId()
• EntityManager#reset - if the world is empty, resets entity id generation to 0
• Optimized entity subscriptions: compositionId pre-calculated and bundled
  by AspectSubscriptionManager before informing listeners.
• Fix: ComponentMapper was accidentally marked as final in RC1.

Version: 2.0.0-RC1 - 2016-05-09

• BREAKING CHANGES
  • Methods added to interface Injector#getRegistered(Class|String)
  • ComponentMapper#getSafe deprecated, #get is sufficient for all use-cases now.
    due to mappers always growing their backing arrays to accomodate the highest entity id.
  • Calling BaseSystem#process will now run the system, even if setEnabled(false) has been called.
    SystemInvocationStrategy now tracks which systems are enabled/disabled.
    (you may want to update your custom SystemInvocationStrategy implementations).
  • Bag#getData throws ClassCastException when container wasn't created with any of the
    typed constructors.
• Optional manager: EntityLinkManager, discovery and maintenance of relationships between entities.
  • Automatically tracks component fields: @EntityId int, Entity, @EntityId IntBag, Bag<Entity>
    (shares behavior with serialization).
  • LinkListener for listening in on when links between entities are established, changed or disconnected.
  • Tune behavior with @LinkPolicy, applied on component fields referencing entities.
  • Optimized link accessors via maven/gradle plugin - reflection-based fallback during development.
• @DelayedComponentRemoval guarantees that component is available in SubscriptionListener#removed(IntBag).
• World#getRegistered, retrieves injectable objects programmatically.
• Re-worked EntityEdit logic, less code and more performance.
• ComponentType validates component when first encountered.
• Removed PackedComponent and @PackedWeaver.
• added AspectSubscriptionManager#getSubscriptions
• added Bag(Class<T>) and Bag(Class<T>, int capacity)
• IntBag#get throws ArrayIndexOutOfBoundsException whenever index is greater than the reported size,
  regardless of the size of the underlying array.
• All systems are first injected, after which all systems are initialized. Previously,
  each system was injected/initialized at the same time.
• Serialization
  • new artemis-odb-serializer artifact, used by all serialization backends,
  • Kryo serialization backend: binary with kryo
    (thanks to @piotr-j).
