We don’t need to copy any of the documentation. See above, the docs aren’t
copied there.

[Mike Lerman, 2015/02/23 16:12:11]

Done. I kept the location of the source file, similar to what's on line 11-12.

+ * The class holds a single custom reporting attribute of type unsigned integer
+ * that the application would like to pass during the update server ping.
+ */
+@interface KSUnsignedReportingAttribute : KSReportingAttribute
+
+/**
+ * Creates unsinged reporting attribute using the default lifetime.
+ *
+ * @param value The value of the attribute.
+ * @param name The name of the attribute.
+ * @param aggregationType In the case of system update engine, attribute values
+ * are aggregated between users and reported once for the whole machine. This
+ * parameter controls the aggregationmechinism.
+ * @see KSReportingAggregationType
+ * @param error Standard error parameter.
+ *
+ * @return Reporting attribute object, holding the specified integer value and
+ * initialized with the specified properties (name, aggregation type, etc.). In
+ * case of error, the method returns nil and if @c error is not nil, the method
+ * sets it accordingly.
