+ * @ngdoc directive
+ * @name angular.module.ng.$compileProvider.directive.ng-class
+ *
+ * @description
+ * The `ng-class` allows you to set CSS class on HTML element dynamically by databinding an
+ * expression that represents all classes to be added.
+ *
+ * The directive won't add duplicate classes if a particular class was already set.
+ *
+ * When the expression changes, the previously added classes are removed and only then the classes
+ * new classes are added.
+ *
+ * @element ANY
+ * @param {expression} ng-class {@link guide/dev_guide.expressions Expression} to eval. The result
+ *   of the evaluation can be a string representing space delimited class
+ *   names, an array, or a map of class names to boolean values.
+ *
+ * @example
+   <doc:example>
+     <doc:source>
+      <input type="button" value="set" ng-click="myVar='ng-invalid'">
+      <input type="button" value="clear" ng-click="myVar=''">
+      <br>
+      <span ng-class="myVar">Sample Text &nbsp;&nbsp;&nbsp;&nbsp;</span>
