问题 I am having problems getting my head around generics in the following situation, see inline comments below for my questions: public void exampleMethod() { //Intuitively I would expect this to mean that test is set containing objects //that subclass AbstractGroup Set<? extends AbstractGroup> test; //Yet the compiler complains here and I do not understand why? test.add(new AnyAbstractGroupSubGroup()); //I would guess that a method call such as this at runtime test = new HashSet<SubGroupA>() /

问题 I want a batch file to copy files from a folder, which changes every month, to another folder but it seems Windows command prompt doesn't like wildcards. Example: I want to copy the folder media1 and containing files in this directory: K:\Eng\NAVDB\Navigation Databases\Current\FI8_Icelandair_B75_76\FI81711001\FI81711001\FI81711_AHDF.001\OM_LOCAL_FLOPPY_1.44MB_S520_v1_1\media1 To this directory K:\Eng\NAVDB\Navigation Databases\Current\FI8_Icelandair_B75_76\ . But the 1711 part of folders

问题 I have an NSString, let's say "H,L,K,P" how can I detect a specific character than then a wild-car character... for example, checking for ",*" would return ",L" ",K" and ",P" because they all have the specific "," and then they all have a character after them. Then I want to replace that string with itself plus a "period" appended to it. So "H,L,K,P" would become "H,L.,K.,P." 回答1: Use a regular expression. The search pattern would be: ,(.) the replacement pattern would be: ,$1. Sample code:

问题 I've been doing this all the time: result = subprocess.call(['copy', '123*.xml', 'out_folder\\.', '/y']) if result == 0: do_something() else: do_something_else() Until today I started to look into pywin32 modules, then I saw functions like win32file.CopyFiles(), but then I found it may not support copying files to a directory. Maybe this functionality is hidden somewhere, but I haven't found it yet. I've also tried "glob" and "shutil" combination, but "glob" is incredibly slow if there are

问题 I'm using a js library inside a PhoneGap application for iPhone. I don't know what other external sites my js library contacts, so I need a way of whitelisting all connections, just for testing. How do I do that? My app just silently fails, it doesn't continue from where the library is initiated. (when I run the app in a browser it works perfectly) 回答1: Try setting the value of the ExternalHosts property in Phonegap.plist to * 回答2: i think you need to add the domain names to PhoneGap.plist

问题 How do Unix filename wildcards work from Python ? A given directory contains only subdirectories, in each of which there is (among others) one file whose name ends with a known string, say _ext . The first part of the filename always varies, so I need to get to the file by using this pattern. I wanted to do this: directory = "." listofSubDirs = [x[0] for x in os.walk(directory)] listofSubDirs = listofSubDirs[1:] #removing "." for subDirectory in listofSubDirs: fileNameToPickle = subDirectory
