Type Parameters
- TSource
The type of source.
- TResource
The type of resource.
Parameters
- resourceFactory
Type: System.Func<TResource>
The factory function to obtain a resource object.
- observableFactory
Type: System.Func<TResource, IObservable<TSource>>
The factory function to obtain an observable sequence that depends on the obtained resource.
Return Value
Type: System.IObservable<TSource>
The observable sequence whose lifetime controls the lifetime of the dependent resource object.
