Leadtools.Jpip.Server Namespace : DelegatedServer Class |
public class DelegatedServer
'Declaration Public Class DelegatedServer
'Usage Dim instance As DelegatedServer
public sealed class DelegatedServer
function Leadtools.Jpip.Server.DelegatedServer()
public ref class DelegatedServer
You create an instance of this class with the properties you want and then you add it to the DelegatedServersCollection collection.
If multiple DelegatedServer are added into the DelegatedServersCollection collection the load is distributed based on a round-robin algorithm until each DelegatedServer receives its share.
