R: Named lists and description lists

由 自古美人都是妖i 提交于 2021-02-04 18:41:10
问题 R has two classes not so commonly used: "Dlist" and "namedList". As regard the first, it is mentioned with respect to Sys.getenv() , which returns a result of class "Dlist" if its argument is missing, for nice printing. There is in fact a print.Dlist method for the class. There is also an apparently related formatDL function to format description lists. However I do not know how to create an object of class "Dlist". As regards "namedList", it is defined by the manual: the alternative to "list

XAML: Can I refer to a Grid row or column by name?

由 …衆ロ難τιáo~ 提交于 2020-05-25 08:30:01
问题 If I name each row and column in a grid, can I set a control's grid.row="Row_Top"? I have defined StaticResources to refer to it but is there a converter or some other method to accomplish this without the resource? 回答1: As far as I know there's no built-in way to do it... however, you could use markup extensions to retrieve a row or column by its name : [MarkupExtensionReturnType(typeof(int))] public abstract class GridBandExtensionBase : MarkupExtension { public override object ProvideValue

Are Hibernate named HQL queries (in annotations) optimised?

由 牧云@^-^@ 提交于 2020-01-02 03:28:08
问题 A new colleague has just suggested using named HQL queries in Hibernate with annotations (i.e. @NamedQuery) instead of embedding HQL in our XxxxRepository classes. What I'd like to know is whether using the annotation provides any advantage except for centralising queries? In particular, is there some performances gain, for instance because the query is only parsed once when the class is loaded rather than every time the Repository method is executed? 回答1: from Pro EJB 3 (Mike Keith): "...we
