• Java application profiling / tracking

  - by sarav

  I have a closed source Java application for which vendor has provided APIs for customization. As I have no other documents, i rely completely on the API's javadoc. I want to trace what methods are actually called in different classes for a particular use case. Is there any way to do that with eclipse?

• Implementing prototypes OR instantiating class objects

  - by intuited

  I'm wondering how to implement prototypal inheritance in Python. It seems like the way to do this would be to either use a metaclass to cause instantiations to actually be classes, rather than objects, or use some magical powers to transform an existing object into a class. The second method would seem to be more flexible, in that it could be applied to existing objects of varied types, while the first would likely be more convenient for typical use cases. Insights on the practicality of these two approaches, as well as alternative suggestions, are hereby requested.

  Is there a way to use jdt ASTParser to get the value of a String field declared in a java file. Actually what I need is to resolve any possible dependencies from other classes e.g. public String str = "somethig"+SomeTherClass.SOMETHING_ELSE.

  - by Amitabh

  I was just looking into the source code of an existing project which uses nHibernate and found that there are interfaces created for each entity classes. E.g ICustomer for Customer class. I was just wondering what can be the advantage of this pattern as ICustomer contains mainly the properties and very few methods.

• Difference between a Deprecated and an Legacy API?

  - by Vaibhav Bajpai

  I was studying the legacy API's in the Java's Collection Framework and I learnt that classes such as Vector and HashTable have been superseded by ArrayList and HashMap. However still they are NOT deprecated, and deemed as legacy when essentially, deprecation is applied to software features that are superseded and should be avoided, so, I am not sure when is a API deemed legacy and when it is deprecated.

• Why is the new Tuple type in .Net 4.0 a reference type (class) and not a value type (struct)

  - by Bent Rasmussen

  Does anyone know the answer and/or have an oppinion about it? Since tuples would normally not be very large I would assume it would make more sense to use structs than classes for these. What say you?

  - by dacay

  In Java, is there any way to create an instance of any class that extends abstract class A, inside a member method of class A? Classes that extends abstract class A will return their instances with this method, but i don't want to implement same method in all subclasses with a "return this();" kind line.

• [boost::filesystem] performance: is it better to read all files once, or use b::fs functions over an

  - by rubenvb

  I'm conflicted between a "read once, use memory+pointers to files" and a "read when necessary" approach. The latter is of course much easier (no additional classes needed to store the whole dir structure), but IMO it is slower? A little clarification: I'm writing a simple build system, that read a project file, checks if all files are present, and runs some compile steps. The file tree is static, so the first option doesn't need to be very dynamic and only needs to be built once every time the program is run. Thanks

• When does Java's JVM unzip jar files?

  - by TwentyMiles

  Java's jar file format builds off of the zip file format, and supports compression of the class files inside it. When and how does the JVM decide which class files to uncompress and pull out of the jars on its classpath? Is the process dynamic and done at runtime as classes are needed, or are they all uncompressed up front before the program actually runs?

• Subsonic class has reference to HttpContext.Current.User in a Windows app

  - by Darkwater23

  Hello! I'm using SubSonic 2.1. I ran it against a database and it created all the files seemingly correctly. However, when I went to use one of the classes, the app wouldn't built. I'm making a Windows application, but in the SubSonic file there's a reference to HttpContext.Current.User. Does anyone know why that would happen?

• When should one create interface for request or response for messaging within the application

  - by Nayn

  Hi, I want to know if there is any need to create interface for request/response objects. I know ServletRequest is an interface. I see request/response as simple pojo, where having some members to hold data and getter/setters would suffice. The processing of such data could be delegated to external utility classes. Does anyone have specific inputs on this? Thanks Nayn

  Problem/Task: Write an interface with one method and two classes that implement this interface. Now write a main method with an array that holds an instance of each class. Using a for-each loop, invoke the method upon each item. Is this an interview question? (I'm not sure if the author meant to post this as a question or was looking for an answer to the above.)

• Ruby: Allowing a module to have settings

  - by JP

  If I'm building a library in ruby, what's the best way to allow users of the library to set module-wide settings that will be available to all sub classes etc of the library? A good example would be if I'm writing a library for posting to a webservice: TheService::File.upload("myfile.txt") # Uploads anonymously TheService::Settings.login("myuser","mypass") # Or any other similar way of doing this TheService::File.upload("myfile.txt") # Uploads as 'myuser' The idea would be that unless TheService::Settings.logout is called then all TheService operations would be conducted under myuser's account. Any ideas?

• Can a trait state if a C++ class has a default constructor?

  - by Vicente Botet Escriba

  Traits classes can be defined to check if a C++ class has a member variable, function or a type (see here). Curiously, the ConceptTraits do not include traits to check if a C++ class defines a default constructor or given constructor? Can traits be used to check the constructor presence? If yes, how? If not, why it is not possible?

• SQL Server using SSH-tunnel from Visual Studio

  - by pbt

  Hi, I recently contacted a web host regarding support for external database access to a Microsoft SQL Server database included in a package they offer. They replied saying that it is only possible with an SSH-tunnel. Is it possible to connect to a SQL Server database in Visual Studio using an SSH-tunnel? It is important for me to be able to access the database from my local machine (for debugging, generating LINQ classes, editing tables, etc). Or, how should I go about working with their database?
