CapabilityInject (forge 1.16.5)

```
@Retention(RUNTIME)
@Target({FIELD,METHOD})
public @interface CapabilityInject
```
When placed on a FIELD, the field will be set to an instance of Capability once that capability is registered. That field must be static and be able to hold a instance of 'Capability' Example:
```
 @CapabilityInject(IExampleCapability.class)
 private static final Capability TEST_CAP = null;
 
```
When placed on a METHOD, the method will be invoked once the capability is registered. This allows you to have a 'enable features' callback. It MUST have one parameter of type 'Capability; Example:
```
 @CapabilityInject(IExampleCapability.class)
 private static void capRegistered(Capability cap) {}
 
```
Warning: Capability injections are run in the thread that the capablity is registered. Due to parallel mod loading, this can potentially be off of the main thread.
