    • Adds a handler. You get back an id which can be used to remove the handler later.

      Handlers can be added with 'once' flag set to true. This will automatically remove them after the first value is sent to them.

      If handler returns true, subsequent handlers are not invoked.

      • handler: Dispatch<V>
      • options: { once?: boolean } = {}

      Returns string

    • Emit a value to all handlers Returns true if at least one handler reported 'true' as a response. Also returns true

      Parameters

    • Remove a handler by its id.

      Parameters
