Comentarios

Un objeto debe implementar la ISponsor interfaz si necesita solicitar una renovación de concesión para un objeto determinado. Un objeto que implementa la ISponsor interfaz puede convertirse en un patrocinador registrándose con el administrador de concesiones. El ISponsor servicio de duración utiliza la interfaz para volver a llamar al patrocinador.

Métodos

Renewal(ILease)

Solicita un cliente patrocinador para renovar el período del objeto especificado.
