MashRemoteObject

If you RPC a lot using Dp, you will love this.

MashRemoteObject is a class that hides the underlying Dp calls for you. It makes remote object behave like local objects.

Say you want to control a camera on a remote machine. You can do this:

    set socket [dp_MakeRPCClient camera.bmrc.berkeley.edu 4222]
    set camera [new MashRemoteObject $socket new VCC3Camera]
    $camera pan 40
    $camera zoom 1
    free $camera

We are making calls to $camera as if it is a local object! This is cool because if you do not want to use client-server architecture and want to run your code on the machine that controls the camera, all you need to do is remove "dp_MakeRPCClient" and replace "new MashRemoteObject ..." with "new VCC3Camera". All the camera control code will work the same!

WARNING:

MashRemoteObject does not marshall/unmarshall data. So you can only pass by value.

Always keep in mind the cost of RPC when using MashRemoteObject. Even though the syntax is the same for remote calls and local calls, the cost are not the same!
