JAXB: How to suppress surrounding XmlElement when using XmlJavaTypeAdapter?

由 ￣綄美尐妖づ 提交于 2019-12-20 04:54:20
问题 I use @XmlJavaTypeAdapter to transform Map<String, MapItem> objects into List<MapItem> when marshalling (and vice versa when unmarshalling.) The list always has a surrounding @XmlElement and I want to get rid of it as it clutters the resulting XML. How can this be done? Or, in other words, how can I get rid of element map in the following XML: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <top> <map> <item val="some-val" key="some-key"/> </map> </top> Class MapItem is a simple class

How to suppress all JavaScript runtime errors?

由 大兔子大兔子 提交于 2019-12-17 19:35:18
问题 How can I suppress all JavaScript runtime error popups, from the programmers side? 回答1: To suppress all JavaScript errors there seems to be a window.onerror event. If it is replaced as early as possible(e.g. right after the head) by a function which returns true - there will be no error popups, which is quite useful after debugging is done. <head> <script type="text/javascript"> window.onerror = function(message, url, lineNumber) { // code to execute on an error return true; // prevents

Disabling browser status bar text

由 可紊 提交于 2019-12-12 07:47:42
问题 Background Modern browsers do away with the classic status bar and instead draw a small tooltip at the bottom of their windows that displays the link target on hover/focus. An example of this (undesirable, in my case) behavior is illustrated in the following screenshot: Questions Is there a portable way to disable these tooltips? Am I missing any obvious drawbacks to doing this in my particular situation? Is my attempt (see below) a reasonable way of accomplishing this? Reasoning I am working

Open plots in a null device

由 為{幸葍}努か 提交于 2019-12-11 09:22:39
问题 I'm using the treemap package and I'm happy with how tmPlot arranges plot rectangles, I want to extract the grid for my own different plots. An example is as follows: library(treemap) data(GNI2010) dat <- tmPlot(GNI2010, index=c("continent", "iso3"), vSize="population", vColor="GNI", type="value")[[1]][[1]] This way I can store the coordinates of the rectangles I want. The catch is that it produces a plot as well. I can see a couple of ways to prevent the plot from being produced: .Call("R_GD
