Subject	[platform-dev] How can an object determine which plugin it was        instantiated?

Hi.
 
I’ve created a generic plugin with
a couple of abstract classes. Specialized plugins are using this generic
plugin’s functionality. Sometimes the classes in generic plugin have to
know in which specialized pligin they were instantiated. Let me clarify
the concrete problem:
 
public abstract class GenericPlugin
extends AbstractUIPlugin {
           
    private CommandMapping commandMapping;
 
           
    public void start( BundleContext context ) {
           
                   commandMapping
= instantiateCommandMapping();
           
    }
 
           
    public CommandMapping getCommandMapping() { return commandMapping;
}
 
           
    publc static GenericPlugin getInstance( String pluginName
) { return PlguinRegistry.get( pluginName ); }
           
    
           
    protected CommandMapping instantiateCommandMapping();
}
 
public class SpecificPlugin extends
GenericPlugin {
           
    protected CommandMapping instantiateCommandMapping() {
           
                   return
new SpecificCommandMapping();
           
    }
}
 
public abstract class ActionDelegate
implements IWorkbenchWindowActionDelegate {
           
    private CommandMapping commandMapping;
 
           
    public void init( IWorkbenchWindow window ) {
           
                   commandMapping
= GenericPlugin.getInstance( pluginName ).getCommandMapping();
           
    }
}
 
public class SpecificActionDelegate
extends GenericActionDelegate {
           
    public void init(IWorkbenchWindow window ) {
           
                   super(
window );
           
    }
}
 
The line: GenericPlugin.getInstance(
pluginName ) is crucial because I don’t know how can I determine the plugin’s
name within which the object SpecificActionDelegate was instantiated. 
 
Do you have any idea?
