Class DiagramServer

      net.sf.sdedit.server.DiagramServer

All Implemented Interfaces:

Runnable

public class DiagramServer
extends Thread

This class implements a simple server that uses a TCP socket to receive a diagram source text and to send an image of the resulting diagram.

The exchange must follow this simple protocol:

1. The client sends the mimetype of the image he would like to receive.
2. The client sends the diagram source text.
3. The client sends 'END'
4. • If the diagram cannot be created due to an error, the server sends a message starting with 'ERROR:' and ending with a description of the error.
   • Otherwise the server sends the image data.

There are currently two mime-types supported:

1. image/png
2. image/svg+xml (requires the SVG plugin)
