Control.IDelegateEvent<'Delegate> Interface (F#)

  • Artikel

First class event values for arbitrary delegate types.

Namespace/Module Path: Microsoft.FSharp.Control

Assembly: FSharp.Core (in FSharp.Core.dll)

type IDelegateEvent<'Delegate> =
 interface
  abstract this.AddHandler : 'Delegate -> unit
  abstract this.RemoveHandler : 'Delegate -> unit
 end

Remarks

F# gives special status to member properties compatible with type IDelegateEvent and tagged with the CLIEventAttribute. In this case the F# compiler generates approriate CLI metadata to make the member appear to other CLI languages as a CLI event.
