  • HashMap.containsValue - What's the point?

    - by Frederik
    I've got a HashMap and I need to fetch an item by its integer value. I notice there's a containsValue() function, but it would appear I still have to iterate through the map to find the correct index anyway. My question is; why use containsValue() if I'm required to traverse it afterwards? Also, am I missing the point completely? ;-)

  • getline with ints C++

    - by Mdjon26
    I have a file 0 3 2 1 2 3 4 5 6 6 8 1 Where the first number for each line is the row, the second number is the column, and the third number is the data contained in that row, column. This will be a given [8][8] array so I have already initialized everything to 0, but how can I store each of these data values? For example, I want [0][3] =2 and [1][2] = 3. I would like to keep track of the line on which I found that row, col, and data value. So, how can I correctly insert these values into my 2-D array? int rowcol[8][8]; for (int i=0; i < 9; i++) for (int j=0; j < 9; j++) { rowcol[i][j] =0; } ifstream myfile; int nums; myfile.open(text.c_str()); while (!myfile.eof()) { myfile >> nums; numbers.push_back(nums); } for (int i=0; i < numbers.size(); i++) { //Not sure what the best approach here would be and I'm not even sure if I should have done a vector... }

  • Call to a member function ... on a non-object

    - by jayceekay
    i have an object which is instantiated in an initialize file, which is called with every request. the name is right, so why is it telling me that oourls isn't an object and that redirectLoggedIn isn't its method? a var dump on oourls says NULL. but it's instantiated, and the backtrace at the bottom shows that it goes through initialization and instantiates it. pretty small snippet of code, here's the relevant bit: if($email) { global $session; $session->grantLogin($email); global $oourls; $oourls->redirectLoggedIn(); } else { return false; } and here's the output of debug_print_backtrace i threw in above the oourls method call because i'm completely confused: #0 accounts::verifyEmailRegisterAccount(37a6274c8f4bfa5c537b40e8e04d634a) called at [\public\includes\default\verifyemail.php:16] #1 require_once(\public\includes\default\verifyemail.php) called at [\support\php\ObjectOrientedURLs.class.php:48] #2 ObjectOrientedURLs->mhqqrVerifyemail(Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) #3 ReflectionMethod->invoke(ObjectOrientedURLs Object (), Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) called at [\support\php\ObjectOrientedURLs.class.php:280] #4 ObjectOrientedURLs->parseAndInvokeURL() called at [\support\php\ObjectOrientedURLs.class.php:255] #5 ObjectOrientedURLs->__construct() called at [\support\php\initialize.php:76] #6 require_once(\support\php\initialize.php) called at [\public\index.php:2]

    Greetings, The question relates to ASP.NET MVC I am creating some divs dynamically using AJAX (some views render dynamically). Inside these views a have some JS code. When user click on link i would like to open dialog box with google map. However, because these views are rendered dynamically it does not work because js code is not injected (what can be seen in page source). How can I resolve this problem?

  • c# logic to get the first non-repeating(distinct) character from the string

    - by NoviceToDotNet
    In c# i want to create logic that if i a string like abcabda is passed to a method then it should return first non repeative character from string like in above it should return c. i am unable to convert a string to array of character then how to make comparison of each array character to the string and return the first non repeative character. CanI make it like this? class A { static void main() { A a=new A(); char ch=a.m1(abcabd); } } class B { char m1(string s) { string s1=s; char[] ch1=new char[s.length]; for(int x=0; x<s.length;x++) { ch1[x]=s[x]; } for(int x=0; x<s.length; x++) { for(int y=0; y<s.lenth; y++) { if(s[x]=ch1[y]) { /// here i am confused how to create logic for comparison please let me know // and how to return the character } } } } }

  • What happens with $q.all() when some calls work and others fail?

    - by Alan
    What happens with $q.all() when some calls work and others fail? I have the following code: var entityIdColumn = $scope.entityType.toLowerCase() + 'Id'; var requests = $scope.grid.data .filter(function (rowData, i) { return !angular.equals(rowData, $scope.grid.backup[i]); }) .map(function (rowData, i) { var entityId = rowData[entityIdColumn]; return $http.put('/api/' + $scope.entityType + '/' + entityId, rowData); }); $q.all(requests).then(function (allResponses) { //if all the requests succeeded, this will be called, and $q.all will get an //array of all their responses. console.log(allResponses[0].data); }, function (error) { //This will be called if $q.all finds any of the requests erroring. var abc = error; var def = 99; }); When all of the $http calls work then the allResponses array is filled with data. When one fails the it's my understanding that the second function will be called and the error variable given details. However can someone help explain to me what happens if some of the responses work and others fail?

  • How do I create a self referential association (self join) in a single class using ActiveRecord in Rails?

    - by Daniel Chang
    I am trying to create a self join table that represents a list of customers who can refer each other (perhaps to a product or a program). I am trying to limit my model to just one class, "Customer". The schema is: create_table "customers", force: true do |t| t.string "name" t.integer "referring_customer_id" t.datetime "created_at" t.datetime "updated_at" end add_index "customers", ["referring_customer_id"], name: "index_customers_on_referring_customer_id" My model is: class Customer < ActiveRecord::Base has_many :referrals, class_name: "Customer", foreign_key: "referring_customer_id", conditions: {:referring_customer_id => :id} belongs_to :referring_customer, class_name: "Customer", foreign_key: "referring_customer_id" end I have no problem accessing a customer's referring_customer: @customer.referring_customer.name ... returns the name of the customer that referred @customer. However, I keep getting an empty array when accessing referrals: @customer.referrals ... returns []. I ran binding.pry to see what SQL was being run, given a customer who has a "referer" and should have several referrals. This is the SQL being executed. Customer Load (0.3ms) SELECT "customers".* FROM "customers" WHERE "customers"."id" = ? ORDER BY "customers"."id" ASC LIMIT 1 [["id", 2]] Customer Exists (0.2ms) SELECT 1 AS one FROM "customers" WHERE "customers"."referring_customer_id" = ? AND "customers"."referring_customer_id" = 'id' LIMIT 1 [["referring_customer_id", 3]] I'm a bit lost and am unsure where my problem lies. I don't think my query is correct -- @customer.referrals should return an array of all the referrals, which are the customers who have @customer.id as their referring_customer_id.

  • Compression Program in C

    - by Delandilon
    I want to compress a series of characters. For example if i type Input : FFFFFBBBBBBBCCBBBAABBGGGGGSSS (27 x 8 bits = 216 bits) Output: F5B7C2B3A2B2G5S3 (14 x 8 bits = 112bits) So far this is what i have, i can count the number of Characters in the Array. But the most important task is to count them in the same sequence. I can't seem to figure that out :( Ive stared doing C just a few weeks back, i have knowledge on Array, pointers, ASCII value but in any case can't seem to count these characters in a sequence. Ive try a bit of everything. This approach is no good but it the closest i came to it. #include <stdio.h> #include <conio.h> int main() { int charcnt=0,dotcnt=0,commacnt=0,blankcnt=0,i, countA, countB; char str[125]; printf("*****String Manipulations*****\n\n"); printf("Enter a string\n\n"); scanf("%[^'\n']s",str); printf("\n\nEntered String is \" %s \" \n",str); for(i=0;str[i]!='\0';i++) { // COUNTING EXCEPTION CHARS if(str[i]==' ') blankcnt++; if(str[i]=='.') dotcnt++; if(str[i]==',') commacnt++; if (str[i]=='A' || str[i]=='a') countA++; if (str[i]=='B' || str[i]=='b') countA++; } //PRINT RESULT OF COUNT charcnt=i; printf("\n\nTotal Characters : %d",charcnt); printf("\nTotal Blanks : %d",blankcnt); printf("\nTotal Full stops : %d",dotcnt); printf("\nTotal Commas : %d\n\n",commacnt); printf("A%d\n", countA); }

  • Overload the behavior of count() when called on certain objects

    - by Tom
    In PHP 5, you can use magic methods, overload some classes, etc. In C++, you can implement functions that exist is STL as long as the argument types are different. Is there a way to do this in PHP? An example of what I'd like to do is this: class a { function a() { $this->list = array("1", "2"); } } $blah = new a(); count($blah); I would like blah to return 2. IE count the values of a specific array in the class. So in C++, the way I would do this might look like this: int count(a varName) { return count(varName->list); } Basically, I am trying to simplify data calls for a large application so I can call do this: count($object); rather than count($object->list); The list is going to be potentially a list of objects so depending on how it's used, it could be really nasty statement if someone has to do it the current way: count($object->list[0]->list[0]->list); So, can I make something similar to this: function count(a $object) { count($object->list); } I know PHP's count accepts a mixed var, so I don't know if I can override an individual type.

  • Arrays (toString) not output correctly

    - by DiscoDude
    Hello, Actually this tread is continuing from the other one. There wasn't enough characters to continue there. Anyway. the problem is that the output is "1(10) 2(23) 3(29)". Even though I could return string for the array values (10,23,29) and used string reference as 1, 2 and 3. My question is it possible to return index values 1,2,3 and as well as array values. Am I making an sense. Here is what I have done... // int[] groups = {10, 23, 29}; in the constructor String tempA = ""; String tempB = " "; int[] temp = new int[4]; int length = groups.length; for (int j = 0; j < length; j++) { temp[j] = groups[j]; tempB = tempB + "("+goups+")"; } groups = temp; Arrays.sort(coingroups); for(int i = 1; i < groups.length;i++) { tempA = tempA+" "+(i)+ "("+groups[i]+")"; } return tempA;

  • Avoiding instanceof in Java

    - by Mark Lutton
    Having a chain of "instanceof" operations is considered a "code smell". The standard answer is "use polymorphism". How would I do it in this case? There are a number of subclasses of a base class; none of them are under my control. An analogous situation would be with the Java classes Integer, Double, BigDecimal etc. if (obj instanceof Integer) {NumberStuff.handle((Integer)obj);} else if (obj instanceof BigDecimal) {BigDecimalStuff.handle((BigDecimal)obj);} else if (obj instanceof Double) {DoubleStuff.handle((Double)obj);} I do have control over NumberStuff and so on. I don't want to use many lines of code where a few lines would do. (Sometimes I make a HashMap mapping Integer.class to an instance of IntegerStuff, BigDecimal.class to an instance of BigDecimalStuff etc. But today I want something simpler.) I'd like something as simple as this: public static handle(Integer num) { ... } public static handle(BigDecimal num) { ... } But Java just doesn't work that way. I'd like to use static methods when formatting. The things I'm formatting are composite, where a Thing1 can contain an array Thing2s and a Thing2 can contain an array of Thing1s. I had a problem when I implemented my formatters like this: class Thing1Formatter { private static Thing2Formatter thing2Formatter = new Thing2Formatter(); public format(Thing thing) { thing2Formatter.format(thing.innerThing2); } } class Thing2Formatter { private static Thing1Formatter thing1Formatter = new Thing1Formatter(); public format(Thing2 thing) { thing1Formatter.format(thing.innerThing1); } } Yes, I know the HashMap and a bit more code can fix that too. But the "instanceof" seems so readable and maintainable by comparison. Is there anything simple but not smelly?

    Hi, is it possible to have the controller value in a rails named route as a parameter, which I can pass at runtime to direct the call to the proper controller? e.g. map.ride 'ride' ,:controller = {some-way-of-specifying-a-parameter}, :action = 'ride' then at runtime, I want to pass the controller name to which this call should be going. My actions are doing different things depending to which controller the call gets sent. thanks

  • java:25: '.class' expected error while merging arrays

  • .Net file writing and string splitting issues

    - by sagar
    I have a requirement where the file should be split using a given character. Default splitting options are CRLF and LF In both these cases I am splitting the line by \r\n and \r respectively. Also I have requirement where any size of file should be processed. (Processing is basically inserting the given string in a file at given position). For this I am reading the file in chunk of 1024 bytes. Then I am applying the string.Split() method. Split() method gives options for ignoring white spaces and none. I have to add back these line break characters to the line. for this I am using a binary writer and I am writing the byte array to the new file. Issue:- 1) When line break is CRLF, and the split option is NONE, while spaces are also added in the splitted array. Second option is given (to ignore white spaces) CRLF works properly. 2)Bit ignoring white space option creates other problems, as I am reading the file byte by byte I can't ignore a white space. 3)When line break characters are other than default(e.g. '|', a null value is prepended to the resulting line. Can anybody give solution to my issues?
