Class Pmap

Implemented Interfaces:
XDT
public class Pmap
extends java.lang.Object
implements XDT
The Pmap class is the interface to the portmapper. It can query the portmapper, it can also perform broadcast RPCs.

Constructor Summary

Pmap()
Pmap(int p, int v, int proto, int portno)
When adding an entry to portmapper, one needs to use this constructor and then call the set() method.
