checkConnect

Method in class java.lang.SecurityManager

public void checkConnect(String host,
                         int port)
Throws a SecurityException if the calling thread is not allowed to open a socket connection to the specified host and port number.

A port number of -1 indicates that the calling method is attempting to determine the IP address of the specified host name.

This method calls checkPermission with the SocketPermission(host+":"+port,"connect") permission if the port is not equal to -1. If the port is equal to -1, then it calls checkPermission with the SocketPermission(host,"resolve") permission.

If you override this method, then you should make a call to super.checkConnect at the point the overridden method would normally throw an exception.

Parameters:
host - the host name port to connect to.
port - the protocol port to connect to.
Throws:
SecurityException - if the calling thread does not have permission to open a socket connection to the specified host and port.
