Temporarily disable XDS in AX 2012?

Use the following code as an example:

public void lookup(FormControl _formControl, str _filterStr)

{

    XDSServices XDS = new XDSServices();

    XDS.setXDSState(0); // Disable XDS

    super(_formControl, _filterStr);

    XDS.setXDSState(1); // Enable XDS

}
