This is the action code to invoke the mindmap2requirements transformation:

public class TransformMindmap2Requirements implements
➥ IObjectActionDelegate {

private IWorkbenchPart targetPart;
private URI fileURI;

public void setActivePart(IAction action, IWorkbenchPart targetPart)
{

this .targetPart = targetPart;

}

public void selectionChanged(IAction action, ISelection selection) {
fileURI = null ;
action.setEnabled( false );
if (selection instanceof IStructuredSelection == false ||
selection.isEmpty()) {
return ;

}
IFile file = (IFile) ((IStructuredSelection)
selection).getFirstElement();
fileURI = URI.createPlatformResourceURI(
file.getFullPath().toString(), true );
action.setEnabled( true );

}
