Syntax

C++/CLI

Python

public DelegatedServer( 
   string ipAddress, 
   int port, 
   int hostLoad 
)

public: 
DelegatedServer(  
   String^ ipAddress, 
   int port, 
   int hostLoad 
)

__init__(self,ipAddress,port,hostLoad) # Overloaded constructor

Parameters

ipAddress
Identifies the IP address of the host for the JPIP server that is managing the new channel.

port
Identifies the numerical port number to which the JPIP server that is managing the new channel is listening for requests.

hostLoad
When multiple hosts are added to the DelegatedServersCollection, this parameter specifies the load distributed on each server.

Remarks

This constructor creates a new instance of the DelegatedServer class and adds this newly created DelegatedServer to the DelegatedServersCollection collection.
