• python dictionary conversion from string?

  - by shahjapan

  if I've string like "{ partner_name = test_partner}" OR " { partner_name : test_partner } its an example string will be very complex with several special characters included like =, [ , ] , { , } what will be the best way to convert it into a python object - so I can process it I tried with eval but it requires " ' " for string, but how can we add this special character \' before starting and ending of every word, I tried regular express re.findal('\w+') but it fails when my string contains ' _ ' or like characters as it will separate the string by ' _ ' Object of this question is my application needs, user friendly language as input - and I thought Json Dict will be good - but user is lazzy to put " ' " before and after of each string... then I thought for yaml but its also complex, if anybody can suggest better user friendly input which I use as python object - then please help me out.

• Constructor/Destructor involving a class and a struct

  - by Bogdan Maier

  I am working on a program and need to make an array of objects, specifically I have a 31x1 array where each position is an object, (each object is basically built out of 6 ints). Here is what I have but something is wrong and i could use some help thank you. 31x1 struct header" const int days=31; struct Arr{ int days; int *M; }; typedef Arr* Array; 31x1 matrix constructor: void constr(){ int *M; M = new Expe[31]; // Expe is the class class header: class Expe { private: //0-HouseKeeping, 1-Food, 2-Transport, 3-Clothing, 4-TelNet, 5-others int *obj; } Class object constructor: Expe::Expe() { this->obj=new int[6]; } help please... because i`m pretty lost.

• Creating a function that will handle objects with common properties

  - by geocine

  Take this as an example I have trimmed this example for readability and you may not find the use of this concept here. class Teacher() { public Name {get; set;} public Salt {get; set;} public Department{get; set;} } class Student() { public Name {get; set;} public Salt {get; set;} public Section{get; set;} } public string GetEncryptedName(object Person) { //return encrypted name based on Name and Salt property return encrypt(object.Salt,object.Name) } callig the function GetEncryptedName(Teacher) GetEncryptedName(Student) How do you implement this kind of stuff?

• how to access jquery internal data?

  - by Unknown

  As you may or may not be aware as of jQuery 1.7 the whole event system was rewritten from the ground up. The codebase is much faster and with the new .on() method there is a lot of uniformity to wiring up event handlers. One used to be able to access the internal events data and investiate what events are registered on any given element, but recently this internal information has been hidden based on the following scenario... It seems that the "private" data is ALWAYS stored on the .data(jQuery.expando) - For "objects" where the deletion of the object should also delete its caches this makes some sense. In the realm of nodes however, I think we should store these "private" members in a separate (private) cache so that they don't pollute the object returned by $.fn.data()" Although I agree with the above change to hide the internal data, I have found having access to this information can be helpful for debugging and unit testing. What was the new way of getting the internal jquery event object in jQuery 1.7?

• Flex : Adding a click handler on SkinnableDataContainer's items

  - by sebpiq

  Hi, I am new to Flex. What I am looking for here is adding a click handler on all the items created by a SkinnableDataContainer. I tried several things that didn't work, and I have no idea what is the right way to do it. <s:SkinnableDataContainer id="teamList" itemRenderer="TeamSummaryRenderer"> <s:dataProvider> <s:ArrayList> <fx:Object teamName="A super team 1"/> <fx:Object teamName="A super team 2"/> <fx:Object teamName="A super team 3"/> </s:ArrayList> </s:dataProvider> </s:SkinnableDataContainer> Furthermore, I don't want to declare the handler in my custom TeamSummaryRenderer component. I would prefer that the handler code stays at application level. Is there a simple 'Flex-ish' to achieve this ?

• Combining query rows in a loop

  - by icemanind

  I have the following ColdFusion 9 code: <cfloop from="1" to="#arrayLen(tagArray)#" index="i"> <cfquery name="qryGetSPFAQs" datasource="#application.datasource#"> EXEC searchFAQ '#tagArray[i]#' </cfquery> </cfloop> The EXEC executes a stored procedure on the database server, which returns rows of data, depending on what the parameter is. What I am trying to do is combine the queries into one query object. In other words, if it loops 3 times and each loop returns 4 rows, I want a query object that has all 12 rows in one object. How do I acheive this?

• Stopping looping thread in Java

  - by halfwarp

  I'm using a thread that is continuously reading from a queue. Something like: public void run() { Object obj; while(true) { synchronized(objectsQueue) { if(objectesQueue.isEmpty()) { try { objectesQueue.wait(); } catch (InterruptedException e) { e.printStackTrace(); } obj = objectesQueue.poll(); } } // Do something with the Object obj } } What is the best way to stop this thread? I see two options: 1 - Since Thread.stop() is deprecated, I can implement a stopThisThread() method that uses a n atomic check-condition variable. 2 - Send a Death Event object or something like that to the queue. When the thread fetches a death event it exists. I prefer the 1st way, however, I don't know when to call the stopThisThread() method, as something might be on it's way to the queue and the stop signal can arrive first (not desirable). Any suggestions?

• Conting of objects created in stack and heap for many classes

  - by viswanathan

  What is the best way to count the total number of objects created in both stack and heap for different classes. I know that in C++ new and delete operators can be overloaded and hence in the default constructor and destructor the object count can be incremented or decremented as and when the objects get created or destroyed. Further if i am to extend the same thing for object counting of objects of different classes, then i can create a dummy class and write the object count code in that class and then when i create any new class i can derive it from the Dummy class. Is there any other optimal solution to the same problem.

• StructureMap 'conditional singleton' for Lucene.Net IndexReader

  - by Gareth D

  I have a threadsafe object that is expensive to create and needs to be available through my application (a Lucene.Net IndexReader). The object can become invalid, at which point I need to recreate it (IndexReader.IsCurrent is false, need a new instance using IndexReader.Reopen). I'd like to able to use an IoC container (StructureMap) to manage the creation of the object, but I can't work out if this scenario is possible. It feels like some kind of "conditional singleton" lifecycle. Does StructureMap provide such a feature? Any alternative suggestions?

• Are raw C++ pointers first class objects?

  - by Shailesh Kumar

  According to Wikipedia: An object is first-class when it: can be stored in variables and data structures can be passed as a parameter to a subroutine can be returned as the result of a subroutine can be constructed at runtime has intrinsic identity (independent of any given name) Somebody had once told me that raw pointers are not first class objects while smart pointers like std::auto_ptr are. But to me, a raw pointer (to an object or to a function) in C++ does seem to me to satisfy the conditions stated above to qualify as a first class object. Am I missing something?

• What are some good ways to do intermachine locking?

  - by mike

  Our server cluster consists of 20 machines, each with 10 pids of 5 threads. We'd like some way to prevent any two threads, in any pid, on any machine, from modifying the same object at the same time. Our code's written in Python and runs on Linux, if that helps narrow things down. Also, it's a pretty rare case that two such threads want to do this, so we'd prefer something that optimizes the "only one thread needs this object" case to be really fast, even if it means that the "one thread has locked this object and another one needs it" case isn't great. What are some of the best practices?

• SearchView - Choose between two target Activities according to the query result

  - by vitorgreati

  My application has to do the following: - if the user enters a query that matches exactly an object in my database, a Activity that shows this object should appear; - if the query doesn't match an exact object, a ArrayList with related objects will be returned and an Activity will display this list. So, as I'm using a SearchView on my ActionBar, I want to know how to open the right Activity based on the result of the query, something like this: if(objectFound) openActivityThatShowsThisObject(); else openActivityWithRelatedResults(); I saw in other question that I could use a facade Activity, but I don't know if that is a good approach. Any help will be appreciated, thanks!

• Delete NSManageObject at the event tableView:commiteEditingStyle:forRowAtIndexPath:

  - by David.Chu.ca

  I got exception when I tried to delete one NSManageObject at the event of tableView:commiteEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting?

• How to tell the parent that the thread is done in C++ using pthreads ?

  - by milleroff

  Hi. I have a TCP Server application that serves each client in a new thread using POSIX Threads and C++. The server calls "listen" on its socket and when a client connects, it makes a new object of class Client. The new object runs in its own thread and processes the client's requests. When a client disconnects, i want some way to tell my main() thread that this thread is done, and main() can delete this object and log something like "Client disconnected". My question is, how do i tell to the main thread, that a thread is done ?

• How to change the coordinate of a point that is inside a GraphicsPath?

  - by Ben

  Is there anyway to change the coordinates of some of the points within a GraphicsPath object while leaving the other points where they are? The GraphicsPath object that gets passed into my method will contain a mixture of polygons and lines. My method would want to look something like: void UpdateGraphicsPath(GraphicsPath gPath, RectangleF regionToBeChanged, PointF delta) { // Find the points in gPath that are inside regionToBeChanged // and move them by delta. // gPath.PathPoints[i].X += delta.X; // Compiles but doesn't work } GraphicsPath.PathPoints seems to be readonly, so does GraphicsPath.PathData.Points. So I am wondering if this is even possible. Perhaps generating a new GraphicsPath object with an updated set of points? How can I know if a point is part of a line or a polygon? If anyone has any suggestions then I would be grateful.

• Best way to test instance methods without running __init__

  - by KenFar

  I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little. EDIT: Example solution based on Ignacio's answer: import types class C(object): def __init__(self, number): new_number = self._foo(number) self._bar(new_number) def _foo(self, number): return number * 2 def _bar(self, number): print number * 10 #--- normal execution - should print 160: ------- MyC = C(8) #--- testing execution - should print 80 -------- MyC = object.__new__(C) MyC._bar(8)

• How can I get vimperator to scroll more than one line using the j and k keys?

• How do you determine how coarse or fine-grained a 'responsibility' should be when using the single r

  - by Mark Rogers

  In the SRP, a 'responsibility' is usually described as 'a reason to change', so that each class (or object?) should have only one reason someone should have to go in there and change it. But if you take this to the extreme fine-grain you could say that an object adding two numbers together is a responsibility and a possible reason to change. Therefore the object should contain no other logic, because it would produce another reason for change. I'm curious if there is anyone out there that has any strategies for 'scoping', the single-responsibility principle that's slightly less objective?

• Correct way to add objects to an ArrayList

  - by ninjasense

  I am trying to add an object to an arraylist but when I view the results of the array list, it keeps adding the same object over and over to the arraylist. I was wondering what the correct way to implement this would be. public static ArrayList<Person> parsePeople(String responseData) { ArrayList<Person> People = new ArrayList<Person>(); try { JSONArray jsonPeople = new JSONArray(responseData); if (!jsonPeople.isNull(0)) { for (int i = 0; i < jsonPeople.length(); i++) { Person.add(new Person(jsonPeople.getJSONObject(i))); } } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { } return People; } I have double checked my JSONArray data and made sure they are not duplicates. It seems to keep adding the first object over and over.

  In a binary search tree that takes a simple object.....when creating the getter and setter methods for the left, right, and parent. do I a do a null pointer? as in this=this or do I create the object in each method? Code bellow... This is my code: public void setParent(Person parent) { parent = new Person( parent.getName(), parent.getWeight()); //or is the parent supposed to be a null pointer ???? This is the code it came from: public void setParent(Node parent) { this.parent = parent; } Their code takes a node from the node class...my set parent is taking a person object from my person class.....

• MVC, how view should be accessed from controller?

  - by Kirzilla

  Hello, I'm just learning MVC so you could find my question rather strange... My Controller have access to different shared objects through Container object passed to Controller's constructor. To access shared objects I should do $this-container-db to access Database adapter or $this-container-memcache to access Memcached adapter. I want to know should I put View object into Container with shared objects or no? From one side it is really comfortable to take view from this container, but this way I couldn't create multiple Views instances (for example, every time I'm calling Controller's method from View I should have one more View instance). What is the solution? How should I pass View object into Controller and/or how should I create new View instances from Controller? Thank you!
