NAME

       RpcService - support RPC between a service and its clients

SYNOPSIS

       #include <Dispatch/rpcservice.h>

DESCRIPTION

       An  RpcService (actually, an instance of a derived class) creates a port and listens to it
       for connections from clients.  When a client  opens  a  connection,  the  RpcService  will
       create a reader to handle RPC requests from the connection.

CONSTRUCTORS

       RpcService(int port)
       RpcService(const char* path, int port = 0)
              Start up an RPC service.  If a filename is given, record the RPC service's hostname
              and port number in it so clients can contact the service.  If ``port'' is zero, the
              next free port number will be used.

PUBLIC OPERATIONS

       void run()
       void quitRunning()
              Read  RPC  requests  continuously  until ``quitRunning()'' terminates the loop.  If
              you're using InterViews, you don't have to  call  ``run()''  since  the  InterViews
              event-reading code will also read RPC requests.

PROTECTED OPERATIONS

       virtual void createReader(int fd) = 0
              You  must  define  this function in a derived class in order to start servicing RPC
              requests from a new client.  Typically all you have to do is to construct a  reader
              using  the  passed  file  descriptor  and  make the reader responsible for deleting
              itself when it notices that the connection has been closed by the client.
