___An entity contains no further data.___
In order to be useful, its identifier must be registered to one or more [components](../component/component.md).

Entities are also initialised with a Java [BitSet](https://docs.oracle.com/javase/7/docs/api/java/util/BitSet.html). Each bit represents the index of a component, to determine which component an entity is registered to.

## Notes
* The only requirement for a Entity is that it has a unique ID. A more advanced [entity manager](../manager/entity_manager.md) could implement an ID system with ID regions, or using named IDs.
* The only requirement for a Entity is that it has a unique ID. A more advanced [entity manager](../manager/EntityManager.md) could implement an ID system with ID regions, or using named IDs.
Another approach could be to use the first byte as a grouping, in a similar way to how Bethesda Softworks' Skyrim utilises the first byte as a mod index
* The maximum number of entities is limited by the size of the container used to store it. E.g., for a 32-bit unsigned integer, there are ~4.3 billion ID's available. But keep in mind that such a large amount of IDs will take significant time for each system to consider.
