  • Argument constraints in RhinoMock methods

    - by Khash
    I am mocking a repository that should have 1 entity in it for the test scenario. The repository has to return this entity based on a known id and return nothing when other ids are passed in. I have tried doing something like this: _myRepository.Expect(item => item.Find(knownId)).Return(knownEntity); _myRepository.Expect(item => item.Find(Arg<Guid>.Is.Anything)).Return(null); It seems however the second line is overriding the first and the repository always returns null. I don't want to mock all the different possible IDs asked (they could go up to hundreds) when the test scenario is only concerned with the value of one Id.

  • Calling arrays from other methods in a different class

    - by Jake H
    Hello, I need help dealing with an array in my java program. in my first class, "test", I set 4 variables and then send them to my other class (test2). arr[i] = new test2(id, fname, lname, case); at that point, variables are set and then I want to return those variables. So in the test2 class, I have a method that strictly returns one of those variables public int getId(){ return id; } I understand this is a little stupid, but professor gets what professor wants I guess. What I want to do now is in my main method in "test" I want to retrieve that variable and sort the array based on that int. Unfortunately, I have to create my own sort function, but I think this would work for what I want to do. for(j = 0; j < arr.length; j++){ int indexMin =j; for(i = j; i < arr.length;i++){ if(arr[i] < arr[indexMin]){ indexMin = i; } } int tmp = arr[j]; arr[j] = arr[indexMin]; arr[indexMin] = tmp; } I appreciate any help anyone could provide. Thank you

  • Ruby Module Inclusion in Methods

    - by Federico Builes
    In class Foo I'd like to include method Bar under certain conditions: module Bar def some_method "orly" end end class Foo def initialize(some_condition) if !some_condition "bar" else class << self; include Bar; end end end end Is there any cleaner (and clearer) way to achieve the include in the method without having to do it inside the singleton class?

  • How to implement callback methods inside classes (PHP)

    - by sombe
    I need to use a class callback method on an array inside another method (the callback function belongs to the class). class Database { public function escape_string_for_db($string){ return mysql_real_escape_string($string); } public function escape_all_array($array){ return array_filter($array,"$this->escape_string_for_db"); } } Is this the right way to go about that? (I mean, in terms of the second parameter passed to array_filter)

  • Override java methods without affecting parent behaviour

    - by Timmmm
    suppose I have this classes (sorry it's kind of hard to think of a simple example here; I don't want any "why would you want to do that?" answers!): class Squarer { public void setValue(int v) { mV = v; } public int getValue() { return mV; } private int mV; public void square() { setValue(getValue() * getValue()); } } class OnlyOddInputsSquarer extends Squarer { @Override public void setValue(int v) { if (v % 2 == 0) { print("Sorry, this class only lets you square odd numbers!") return; } super.setValue(v); } } auto s = new OnlyOddInputsSquarer(); s.setValue(3); s.square(); This won't work. When Squarer.square() calls setValue(), it will go to OnlyOddInputsSquarer.setValue() which will reject all its values (since all squares are even). Is there any way I can override setValue() so that all the functions in Squarer still use the method defined there? PS: Sorry, java doesn't have an auto keyword you haven't heard about! Wishful thinking on my part.

  • Sbyte[] vs byte[][] using methods

    - by blgnklc
    It is written byte[][] getImagesForFields(java.lang.String[] fieldnames) Gets an array of images for the given fields. On the other hand, as long as I use the method in the web application project built on asp.net 2.o using c#; the provided web method declared above, returns sbyte; Have a look my code below; formClearanceService.openSession(imageServiceUser); formClearanceService.prepareInstance(formId); byte[][] fieldImagesList = formClearanceService.getImagesForFields(fieldNames); formClearanceService.closeSession(); thus I get the following error: Cannot implicitly convert type 'sbyte[]' to 'byte[][]' So now, 1- should I ask the web service provider what is going on? or 2- any other way that can use the sbyte as I was suppose to use byte[][] like following using: byte[] ssss = fieldImagesList [0]..

  • Ruby - Passing Blocks To Methods

    - by Chris Bunch
    I'm trying to do Ruby password input with the Highline gem and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is: new_pass = ask("Enter your new password: ") { |prompt| prompt.echo = false } verify_pass = ask("Enter again to verify: ") { |prompt| prompt.echo = false } And what I'd like to change it to is something like this: foo = Proc.new { |prompt| prompt.echo = false } new_pass = ask("Enter your new password: ") foo verify_pass = ask("Enter again to verify: ") foo Which unfortunately doesn't work. What's the correct way to do this?

What is the best solution for this scenario ? Please help. Thanks J

  • Ruby Regexp methods?

    - by fjs6
    Is there a gem/example_code that allows to work with regexps? I am not looking for what a regexp can do, but what can be done to a Regexp object. For example: r = Regexp.new(...) r.min_length => the minimum length of a matching string r = Regexp.new("car(less)?") r.min_length => 3 for the string "car" Thanks!

  • Reusing of a PreparedStatement between methods?

    - by MRalwasser
    We all know that we should rather reuse a JDBC PreparedStatement than creating a new instance within a loop. But how to deal with PreparedStatement reuse between different method invocations? Does the reuse-"rule" still count? Should I really consider using a field for the PreparedStatement or should I close and re-create the prepared statement in every invocation? (Of course an instance of such a class would be bound to a Connection which might be a disadvantage) I am aware that the ideal answer might be "it depends". But I am looking for a best practice for less experienced developers that they will do the right choice in most of the cases.

  • Invoking different methods on threads

    - by Kraken
    I have a main process main. It creates 10 threads (say) and then what i want to do is the following: while(required){ Thread t= new Thread(new ClassImplementingRunnable()); t.start(); counter++; } Now i have the list of these threads, and for each thread i want to do a set of process, same for all, hence i put that implementation in the run method of ClassImplementingRunnable. Now after the threads have done their execution, i wan to wait for all of them to stop, and then evoke them again, but this time i want to do them serially not in parallel. for this I join each thread, to wait for them to finish execution but after that i am not sure how to evoke them again and run that piece of code serially. Can i do something like for(each thread){ t.reevoke(); //how can i do that. t.doThis(); // Also where does `dothis()` go, given that my ClassImplementingRunnable is an inner class. } Also, i want to use the same thread, i.e. i want the to continue from where they left off, but in a serial manner. I am not sure how to go about the last piece of pseudo code. Kindly help. Working with with java.

  • How can I make this code more generic

    - by Greg
    Hi How could I make this code more generic in the sense that the Dictionary key could be a different type, depending on what the user of the library wanted to implement? For example someone might what to use the extension methods/interfaces in a case where there "unique key" so to speak for Node is actually an "int" not a "string" for example. public interface ITopology { Dictionary<string, INode> Nodes { get; set; } } public static class TopologyExtns { public static void AddNode(this ITopology topIf, INode node) { topIf.Nodes.Add(node.Name, node); } public static INode FindNode(this ITopology topIf, string searchStr) { return topIf.Nodes[searchStr]; } } public class TopologyImp : ITopology { public Dictionary<string, INode> Nodes { get; set; } public TopologyImp() { Nodes = new Dictionary<string, INode>(); } }

  • Virtual methods as Comp function to sort

    - by wilsongoncalo.mp
    Hello everyone! I'm new to C++ and i'm trying to use std::sort function to sort a vector of Solutions. The code is something like this (solution list is a *vector): void SolutionSet::sort(Comparator &comparator) { std::sort(solutionsList_->begin(), solutionsList_->end(), &comparator::compare); } The comparator param is a Comparator´s child class instance , and the compare method is virtual at Comparator class and implemented by all Comparator's child classes. And i want to use that function as a comparator function at std:sort(). Is this possible? If it is, can someone tell me how? Because with the previous code, it doesn't work. If i've not made myself clear, please just ask! Thank you guys!

  • How are ambigous methods resolved in java ?

    - by Jijoy
    Hi, I have a question. package org.study.algos; public class Study { public static void main(String[] args) { A a = new A(); a.m1(null); } } class A { public void m1(String s) { System.out.println("String"); System.out.println(s); } public void m1(Object obj) { System.out.println("Object"); System.out.println(obj); } } Here, the output is String null Why does the JVM resolve the method to one with a String argument? Thanks in advance J

  • Work with AJAX response with DOM methods

    - by Stomped
    I'm retrieving an entire HTML document via AJAX - and that works fine. But I need to extract certain parts of that document and do things with them. Using a framework (jquery, mootools, etc) is not an option. The only solution I can think of is to grab the body of the HTML document with a regex (yes, I know, terrible) ie. <body>(.*)</body> put that into the current page's DOM in a hidden element, and work with it from there. Is there an easier/better way? Update I've done some testing, and inserting an entire HTML document into a created element behaves a bit differently across browsers I've tested. For example: FF3.5: keeps the contents of the HEAD and BODY tags IE7 / Safari4: Only includes what's between ... Opera 10.10: Keeps HEAD and everything inside it, Keeps contents of BODY The behavior of IE7 and Safari are ideal, but different browsers are doing this differently. Since I'm loading a predetermined HTML document I think I'm going to use the regEx to grab what I want and insert it into a DOM element - unless someone has other suggestions.

  • OO C++ - Virtual Methods

    - by Phorce
    Just a really quick question here. I'm using virtual functions to read in from a text file. Now, it's virtual because in one aspect I want the values to be normalised, and, in the other respect I don't want them to be normalised. I have tried to do this: bool readwav(string theFile, 'native'); So in theory, if the 'native' is used, this method should be called, however, if 'double' is called then a different version of the method is called. Same for if the value is empty, it should just perform the native option. First question, why doesn't the declaration above work? Also, is this the best route to go down? Or, would it be better to have just one class method that switches between the options. Thanks :)

  • index seems to be out of sync for jquery .keydown and .click methods

    - by Growler
    I'd like to navigate images using both keyboard and mouse (clicking left and right arrow images). I'm using Jquery to do this, but the shared imgIndex seems to be off from the .keydown function and the .click function... Whenever .keydown function -- or ++ the imgIndex, isn't that changed index also used in the click function? So shouldn't they always be on the same index? keydown function: <script type="text/javascript"> var imgArray = [<?php echo implode(',', getImages($site)) ?>]; $(document).ready(function() { var img = document.getElementById("showimg"); img.src = imgArray[<?php echo $imgid ?>]; var imgIndex = <?php echo $imgid ?>; alert(imgIndex); $(document).keydown(function (e) { var key = e.which; var rightarrow = 39; var leftarrow = 37; var random = 82; if (key == rightarrow) { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; } if (key == leftarrow) { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; } }); click function: Connected to left and right clickable images $("#next").click(function() { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; }); $("#prev").click(function() { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; }); }); Just so you have some visibility into the getImages php function: <?php function getImages($siteParam) { include 'dbconnect.php'; if ($siteParam == 'artwork') { $table = "artwork"; } else { $table = "comics"; } $catResult = $mysqli->query("SELECT id, title, path, thumb, views, catidFK FROM $table"); $img = array(); while($row = $catResult->fetch_assoc()) { $img[] = "'" . $row['path'] . "'"; } return $img; } ?> Much appreciated! Snapshot of where the script is on "view image.php"

  • Writing Ruby Libraries - hiding methods from outside the module

    - by JP
    Hi all, I'm writing a Ruby library which has a module with a bunch of classes inside it. Many of these classes need to be usable and modifiable by calling scripts, but I don't want (some of) the initializers to be visible/callable: module MyLib class Control def initialize # They can use this end def do_stuff Helper.new('things') end end class Helper # Shouldn't be visible def initialize(what) @what = what end def shout @what end end end c = MyLib::Control.new h = c.do_stuff p h.shout # => "things" # ^ All of this is desired # v This is undesirable p MyLib::Helper.new('!') # => <MyLib::Helper @what='!'> If it's a simple thing, then I'd also appreciate the generated RDoc not even include the .new method for the Helper class either. Any ideas? Thanks for reading!

  • Overriding jQuery plugin methods, as default and for single instances

    - by Kilgore2k
    Hi, The basic question is: How do I perform a basic override of a plugin method without editing the original plugin file? Is it possible to create an override for a specific instance: Example: An rtf plugin uses: $('selector').wysiwyg('setContent',newContent); In order to display the rtf text as readonly I would like for the same method to be applied to a div instead of the body of the IFRAME I would like to overwrite the original 'setContent' with my own code, just for this one element. Thanks
