  • Ruby: Add a method to the class of an input parameter

    - by TJB
    I'm just exploring ruby and was wondering about the theoretical possibility of adding a method to the class of an object. For example, define a method that takes in a parameter and would add a method to the class of that parameter (not just to the parameter object itself). Something like this example: class SomeClass end class AnotherClass end alpha = SomeClass.new beta = AnotherClass.new def AddHelloMethodTo param # This is where I'm trying to # add a method to the class of the parameter def param.class.Hello "Hello" end end AddHelloMethodTo alpha AddHelloMethodTo beta gamma = AnotherClass.new alpha.Hello beta.Hello gamma.Hello (Excuse me if I have syntax errors / typos I'm REALLY new to this!) Notice how I don't call the AddHelloMethodTo on gamma but I expect Hello to be defined because I added it to the class. Is this possible?

  • Method Vs Property

    - by obsoleteattribute
    Hi, I'm a newbie to .NET. I have a class called Project, a project can have multiple forecasts.Now If I want to check if the projects has any forecasts or not should I use a readonly boolean property called HasForecast() or should I use a method named HasForecast() which basically returns a boolean value.From framework design guidelines I came to know that methods should be used when the operation is complex,since here I'm retrieving the value of forecasts from DB should I consider method, or since it is a logical data member should I use a property.If I use a property can I call a method in DBLayer from its getter.Please explain Regards, Ravi

  • Remove border from IFrame

    - by JoelB
    How do I remove the border from an IFrame embedded in my web app? An example of the IFrame is: <IFRAME src="myURL" width=300" height="300">Browser not compatible. </IFRAME> I would like the transition from the content on my page to the contents of the IFrame to be seemless, assuming the background colors are consistent. The target browser is IE6 only and unfortunately solutions for others will not help.

  • Using C++, how to call a base class method from a derived class method and apply this to an object passed as an argument?

    - by Chris
    I can't figure out how to call a base class method from a derived class method but concurrently applying this method call at an object passed as argument. What I mean is this: class Animal { virtual void eat(Animal& to_be_eaten) = 0; }; class Carnivores: public Animal { virtual void eat(Animal& to_be_eaten) { /*implementation here*/} }; class Wolf : public Carnivores { virtual void eat(Animal& to_be_eaten) { /*call eat method(of Base class) of Base to_be_eaten here*/ } } I thought of something like this dynamic_cast<Carnivores&>(to_be_eaten).eat(*this) //and got a segmentation fault Is there any way for this to be done? Thank you! New edit:: Updated the code

  • How to remove files and directories quickly

    - by None
    I am using a mac. When I use the "rm" command it can only remove files. The "rmdir" command only removes empty folders. If you have a directory with files and folders with files and folders in them and so on. Is there anyway to delete all the files and folders without all the strenuous command typing? Remember, I am using the mac bash shell from terminal, not Microsoft DOS or linux.

  • Strange profiling results: definitely non-bottleneck method pops up

    - by jkff
    I'm profiling a program using sampling profiling in YourKit and JProfiler, and also "manually" (I launch it and press Ctrl-Break several times to get thread dumps). All three methods give me extremely strange results: some tens of percents of time spent in a 3-line method that does not even do any allocation or synchronization and doesn't have loops etc. Moreover, after I made this method into a NOP and even removed its invocation completely, the observable program performance didn't change at all (although it got a negligible memory leak, since it was a method for freeing a cheap resource). I'm thinking that this might be because of the constraints that JVM puts on the moments at which a thread's stacktrace may be taken, and it somehow turns out that in my program it is exactly the moments where this method is invoked, although there is absolutely nothing special about it or the context in which it is invoked. What can be the explanation for this phenomenon? What are the aforementioned constraints? What further measurements can I take to clarify the situation?

  • Mercurial Remove History

    - by Jake Pearson
    Is there a way in mercurial to remove old changesets from a database? I have a repository that is 60GB and that makes it pretty painful to do a clone. I would like to trim off everything before a certain date and put the huge database away to collect dust.
