updateItemProperties method

Updates an item's properties in a file on disk when this item instance is a LocalItem.

Updating properties can be only done for local items that are unpacked. For example a mobile map package file (.mmpk) can be unpacked using MobileMapPackage.unpack. Once unpacked local items within the package can be updated see MobileMapPackage.item and for any maps use GeoModel.item. As well as packages, the local item available from an item resource cache can be updated. This is accessed with ItemResourceCache.item. If the package is not unpacked an error of ArcGISExceptionType.commonInvalidCall is returned as an error in the async task.

Return Value: No value.
