Slider step as a binary?

[SG]

Hey gents,

I'm dealing with a slightly odd scenario, I'm trying to make a slider step via binary shifting (So the valid step states of the data point are 1, 2, 4, 8) But since this is being read/written via a standard integer, I can't do the validation on the device side.

Any ideas on how to make this step work inside a standard Mango component? Doesn't have to be a slider, just that would be the most convenient.

Thanks Guys.

The only way I could come up with is to put some code in a user module -

define(['angular', 'require'], function(angular, require) {
'use strict';

var userModule = angular.module('userModule', ['maUiApp']);

userModule.run(['maPoint', function(maPoint) {
    Object.defineProperty(maPoint.prototype, 'bitShiftValue', {
        get: function() {
            return Math.log2(this.value);
        },
        set: function(value) {
            this.setValue(1 << value);
        }
    });
}]);

return userModule;

}); // define

You can then put a slider on the page like this -

<ma-get-point-value  point-xid="multistate-point-xid" point="myPoint"></ma-get-point-value>
<md-slider ng-disabled="!myPoint.enabled" md-discrete step="1" min="0" max="3" ng-model="myPoint.bitShiftValue"></md-slider>

@jared-wiltshire Cool. That works pretty slick.

Thanks Jared.
