VizServices and executing scripts

[amccaskey]

I have a use case where I'd like to interact with the VisIt Viz Service by executing some custom VisIt python code. The IVizService currently doesn't have something like createPlot(String script), is this something that we should think about adding?

Discussed this with @jayjaybillings, it would be better to expose an executeScript method on the VizService interface.

Just to keep track, a VisItVizService.executeScript method could look like this:

public void executeScript(String script) {

    // Get the next available connection for the URI's host.
    Set<String> availableConnections = manager.getConnectionsForHost(host);
    String name = availableConnections.iterator().next();
    // ... check that we have a connection
    IVizConnection<T> connection = manager.getConnection(name);

    VisItSwtConnection widget = connection.getWidget();
    ViewerMethods methods = widget.getViewerMethods();

    for (String line : script.split(“\n”)) {
        methods.processCommands(line);
    }
}

VisIt will no longer be supported in 0.3
