Class VirtualCascade

  anon.infoservice.AbstractDatabaseEntry
      infoservice.dynamic.VirtualCascade

public class VirtualCascade
extends AbstractDatabaseEntry

This class represents a temporary mix-cascade. A cascade is considered temporary if it is not yet physically established. This happens in two szenarios: a) In the semi-dynamic model a last mix' operator selected some mixes for a cascade and the last mix posts the cascade-info to the InfoService. b) The InfoService build new fully dynamic cascades. A temporary cascade becomes a real cascade when the first mix posts a cascade-status for the first time.
