Functions

get C* get(EntityId eid): Returns pointer to the component of type C. Returns null if entity has no such component. Works only with non-flag components.
getComponentStorage auto getComponentStorage(): Returns pointer to the storage of components C. Storage type depends on component type (flag or not).
getOrCreate C* getOrCreate(EntityId eid, C defVal): Returns pointer to the component of type C. Creates component first if entity had no such component. Works only with non-flag components.
has bool has(EntityId eid): Used to check for presence of given component or flag.
load void load(Loader loader, bool removeBeforeRead): Deserializes all component storages from given loader.
query auto query(): Returns query object for given set of component types for iteration with foreach.
registerComponent void registerComponent(): Before using component type in every other method, register it here. name is used for (de)serialization.
remove void remove(EntityId eid): Removes one component for given eid.
remove void remove(EntityId eid): Removes all components for given eid.
removeAll void removeAll(): Removes all components of all types.
removeSerializedComponents void removeSerializedComponents(IoStorageType storageType): Undocumented in source. Be warned that the author may not have intended to support it.
save void save(Saver saver): Serializes all component storages with given saver.
savePartial void savePartial(Saver saver, E entities): Undocumented in source. Be warned that the author may not have intended to support it.
set void set(EntityId eid, Components components): Add or set list of components for entity eid.
