| 4 | * Abstracts ad selection. |

| 6 | * The class allows to modify 'methods' (named callbacks) to provide ads |
| 7 | * through `advanced-ads-ad-select-methods` filter. |
| 8 | * This can be used to replace default methods, wrap them or add new ones. |
| 9 | * |
| 10 | * Further allows to provide ad selection attributes |
| 11 | * through `advanced-ads-ad-select-args` filter to influence behaviour of the |
| 12 | * selection method. |
| 13 | * Default methods have a `override` attribute that allows to replace the |
| 14 | * content. This may be used to defer or skip ad codes dynamically. |
| 15 | * |
| 16 | * @since 1.5.0 |
