# CFPlugInSetLoadOnDemand(_:_:)

Enables or disables load on demand for plug-ins that do dynamic registration (only when a client requests an instance of a supported type).

## Declaration

```swift
func CFPlugInSetLoadOnDemand(_ plugIn: CFPlugIn!, _ flag: Bool)
```

## Parameters

- `plugIn`: The plug-in to be loaded on demand.
- `flag`: true to enable load on demand, false otherwise.

## Discussion

Discussion Plug-ins that do static registration are load on demand by default. Plug-ins that do dynamic registration are not load on demand by default.
