instanceOf in scoped application?

[Peter Farr]

I need to do the equivalent of gr.instanceOf("cmdb_ci_hardware") in a scoped application. The only thing I can come up with is something like this:, which does not seem very efficient. Is there a better way? I am trying to see if a CI is in the Hardware class or any of its subclasses (e.g. Computer).

Bonus question: why is instanceOf missing in the scoped API?

   _isHardware: function(ci){
    
        var related = new GlideRecord("cmdb_ci_hardware");
        related.addQuery("sys_id", ci.sys_id);
        related.addActiveQuery();
        related.setLimit(1);
        related.query();
        if ( related.next() ) {
            return true;
        }
        else {
           return false;
        }
        
    }

Hi,

You can use getRecordClassName() method to return the class of the CI.

Now, why it is not working in scoped app, only ServiceNow can answer it. But you have the above alternative what you can go with.

Thanks for the response Deepak, but I am not looking for the class. I am trying to find out whether the CI is a subclass of another. For example in a legacy application, taking a CI of class Computer, instanceOf("cmdb_ci_hardware") will return true because Computer is a subclass of Hardware.

Check out Scoped GlideTableHierarchy

var table = new GlideTableHierarchy("cmdb_ci_computer"); 
var tables = table.getHierarchy();
var isHardware = (tables.indexOf("cmdb_ci_hardware") > 0);

Perfect Paul. I missed that one. Thanks.
