Detailed Description

This is the base class of all client-side MPS object handles.

It maintains a Connection object and an InputStream and an OutputStream. There is very little behaviour on this object - the automatically-generated subclasses provide all the functionality by making use of this object's protected member variables.

Constructor & Destructor Documentation

protected Proxy::Proxy ( String resolvedName ) [inline, private]

Only invoked by subclass constructors. Creates a connection to the named object, possibly using the naming service passed in, if it is not null. Parameters: resolvedName   the name of the server to create a proxy for Exceptions: MPSException   if anything goes wrong Definition at line 68 of file Proxy.java.

Member Function Documentation

public void Proxy::_disconnect_proxy ( ) [inline, private]

Disconnects this client proxy from the server. Closes the socket. It'd be nice if eventually this was reversible - subsequent calls to methods on the proxy should transparently reconnect and succeed, but currently once the connection is gone, it's gone. Exceptions: MPSException   if anything goes wrong Definition at line 85 of file Proxy.java.

protected org hebe mps InputStream Proxy::getInputStream ( ) [inline, private]

Returns a handle on this proxy's input stream for communication from the server. Definition at line 114 of file Proxy.java.

protected org hebe mps OutputStream Proxy::getOutputStream ( ) [inline, private]

Returns a handle on this proxy's output stream for communication with the server. Definition at line 105 of file Proxy.java.

protected String Proxy::getReference ( ) [inline, private]

Retrieve the canonical name of the server this proxy is connected to. Used (occasionally) to pass references to MPS objects around between MPS interfaces. Returns: the canonical name of the connected server See also: org.hebe.mps.OutputStreamwriteReference Definition at line 97 of file Proxy.java. Referenced by OutputStream::writeReference().
