wildcard

问题 I've been trying to write a Finite State Machine in VHDL code for a simple 16-bit processor I'm implementing on an Altera DE1 board. In the Finite State Machine, I have a CASE statement that handles the different 16-bit instructions, which are brought into the FSM by a 16-bit STD_LOGIC_VECTOR. However, I'm having a little trouble in the decode state where the Finite State Machine decodes the instruction. One of the instructions is an ADD which takes two registers as operands and a third as

问题 I was reading java generics, I came across an interesting query. My question is as follows. For an upper bounded wildcard public static void printList(List<? extends Number> list) { for (int i = 0; i < 10; i++) { list.add(i);// gives compilation error } } For a lower bounded wildcard public static void printList(List<? super Integer> list) { for (int i = 0; i < 10; i++) { list.add(i);// successfully compiles } } I am confused with this because looking at the Sun Oracle documentation I

问题 How can I build in wildcards to my LINQ To SQL lambda expression? This is what I have currently: var query = from log in context.Logs select log; foreach (string filter in CustomReport.ExtColsToFilter) { string tempFilter = filter; query = query.Where(Log => Log.FormattedMessage.Contains(tempFilter)); } This works fine up until I try and pass wildcards in the filter string. I'm experimenting with SqlMethods.Like() but to no avail. The filters above look like this: "<key>NID</key><value>mcass<

问题 I have a website that is basically set up as this: client_name.website.com ...where clientname is actually a wildcard. For every new customer, I create a subdomain basically. I need to automatically get the client name info directly from Apache. For example, if one comes throught: client1.website.com ...I would like to have apache do a SetEnv CLIENT_NAME client1 for me. Since I work with wildcard, it would be nice if this SetEnv would be done dynamically. Really pratical for great amounts of

问题 So I've been trying to solve this assignment whole day, just can't get it. The following function accepts 2 strings, the 2nd (not 1st) possibly containing * 's (asterisks). An * is a replacement for a string (empty, 1 char or more), it can appear appear (only in s2) once, twice, more or not at all, it cannot be adjacent to another * ( ab**c ), no need to check that. public static boolean samePattern(String s1, String s2) It returns true if strings are of the same pattern. It must be recursive

问题 What I am trying to achieve is the following: I want to have numerous subdomains such as abc.domain.com redirect to a url such as www.domain.com/something?subdomain=abc Since I am redirecting to a fully qualified domain, I needed to use a reverse proxy to avoid the change of the URL in the browser. (using the [P] Flag and turning on the mod_proxy module and some other modules) This is my DNS setup *.domain.com. 14400 A 111.111.11.1 This is my virtual host configuration for apache <VirtualHost

问题 I am trying to write a Makefile with my source and object files separated and I can't seem to figure out the proper way to accomplish this. I have two methods that work but I'm hoping someone can point the "correct" way to do this is. My project is separated into a src and obj folder with the Makefile at the same level as these. The first method uses the wildcard function to find the source files in src then uses text replacement to determine the corresponding object files. SRC = $(wildcard

问题 There are often times that I want to execute a command on all files (including hidden files) in a directory. When I try using chmod g+w * .* it changes the permissions on all the files I want (in the directory) and all the files in the parent directory (that I want left alone). Is there a wildcard that does the right thing or do I need to start using find? 回答1: You will need two glob patterns to cover all the potential “dot files”: .[^.]* and ..?* . The first matches all directory entries

问题 I had done a fair share of research before asking this here. Firstly, i would like to create a drop-down filter @accessVar with the ability to select multiple values. It would be easy if not due to my special requirement. My dataset statement is: SELECT PASS_M, ENTRY_DT, EXIT_DT, WORKED_HRS, ACCESS_LOCATION_X, IC_N, COMPANY_M, CONSECUTIVE_D FROM TEMP_TARGET WHERE (CONSECUTIVE_D >= @consecDays) AND (ENTRY_DT BETWEEN @startDate AND @endDate) AND (ACCESS_LOCATION_X LIKE @accessVar) AND (IC_N

问题 Although I've seen a lot of answers for similar questions I can't make the following code work as I think it should: File dataDir = new File("C:\\User\\user_id"); PathMatcher pathMatcher = FileSystems.getDefault() .getPathMatcher("glob:" + "**\\somefile.xml"); try (DirectoryStream<Path> dirStream = Files.newDirectoryStream( dataDir.toPath(), pathMatcher::matches)) { Iterator<Path> itStream = dirStream.iterator(); while(itStream.hasNext()) { Path resultPath = itStream.next(); } } catch
