Name - use this field to specify entry names in the rule. This filter matches only entry names such as field names, method names, class names and etc. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name. Order - use this option to select the sorting order for the rule. This option is useful when more than one element uses the same matching rule. In this case, selecting Keep order will keep the same order as was set before the rearrangement and selecting Order by Name will sort the elements with the same matching rule by their names.
