| GAIA_NODISCARD auto | view () const |
| Returns a read-only entity or component view. | |
| GAIA_NODISCARD auto | view (uint32_t termIdx) |
| GAIA_NODISCARD auto | view_mut () |
| Returns a mutable entity or component view. | |
| GAIA_NODISCARD auto | view_mut (uint32_t termIdx) |
| GAIA_NODISCARD auto | sview_mut () |
| Returns a mutable component view. Doesn't update the world version when the access is acquired. | |
| GAIA_NODISCARD auto | sview_mut (uint32_t termIdx) |
| void | modify () |
| Marks the component T as modified. Best used with sview to manually trigger an update at user's whim. If. | |
| GAIA_NODISCARD auto | view_auto () |
| Returns either a mutable or immutable entity/component view based on the requested type. Value and const types are considered immutable. Anything else is mutable. | |
| GAIA_NODISCARD auto | sview_auto () |
| Returns either a mutable or immutable entity/component view based on the requested type. Value and const types are considered immutable. Anything else is mutable. Doesn't update the world version when read-write access is acquired. | |
| GAIA_NODISCARD bool | enabled (uint32_t index) const |
| Checks if the entity at the current iterator index is enabled. | |
| GAIA_NODISCARD bool | has (Entity entity) const |
| Checks if entity entity is present in the chunk. | |
| GAIA_NODISCARD bool | has (Pair pair) const |
| Checks if relationship pair pair is present in the chunk. | |
| GAIA_NODISCARD bool | has () const |
| Checks if component T is present in the chunk. | |
| GAIA_NODISCARD uint16_t | size () const noexcept |
| Returns the number of entities accessible via the iterator. | |
| uint32_t | acc_index (uint32_t idx) const noexcept |
| Returns the absolute index that should be used to access an item in the chunk. AoS indices map directly, SoA indices need some adjustments because the view is always considered {0..ChunkCapacity} instead of {FirstEnabled..ChunkSize}. | |
