methods

问题 Here is the method: public static boolean startModule(Module mod, ServletContext servletContext, boolean delayContextRefresh) Here is the method call in a java file: WebModuleUtil.startModule(module, getServletContext(), false); I cannot make any changes to these files, but I want to intercept the method and add some of my code (I want access to the parameters as well) Code I wrote in another java file but not successful: public void main(String[] args) throws Exception { Module module = null

问题 I want to define a method that I have in MainActivity in another class that I created. I am having issues figuring this out. Is this even possible? I am not finding anything online about defining a method in another class. I have included my code and the example of how I want to do it. My MainActivity Code package com.example.flashcards; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget

问题 How can I show all the methods that are available in my WCF in a dropdown. I need to show only those methods that are exposed to the client. I have the following code working, but it displays much more methods than expected. Seems it displays all. MethodInfo[] methods = typeof(IntlService.ClientDataServiceClient).GetMethods(); //// sort methods by name Array.Sort(methods, delegate(MethodInfo methods1, MethodInfo methods2) { return methods1.Name.CompareTo(methods2.Name); }); foreach (var

问题 With reference to Non-static member functions, under const-, volatile-, and ref-qualified member functions it is mentioned: A non-static member function can be declared with no ref-qualifier, with an lvalue ref-qualifier (the token & after the parameter list) or the rvalue ref-qualifier (the token && after the parameter list). During overload resolution, non-static cv-qualified member function of class X is treated as follows: no ref-qualifier: the implicit object parameter has type lvalue

问题 I'm a little confused exactly about how polymorphism and extending classes etc... works in Java when creating objects from these classes. I recently had a problem which someone on here helped me resolved (see Not able to access object sub class's variable? (Java / Android)) for background. I was attempting to create an object like so: Quad hero = new Hero(); Where Hero was a subclass of Quad(); I had variables in my Hero class which I wasn't above to access. The solution was to change my

问题 I have a working code from a tutorial but don't understand it completely. Situation: After a button was pressed in my iPhone App an AlertView appears with three buttons. Now I like to check what button the user pressed. CODE FROM THE TUTORIAL: - (IBAction)infoButtonPressed:(id)sender { UIAlertView *myAlert1 = [[UIAlertView alloc]initWithTitle:@"My Alert View 1" message:@"Here we go" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Option1", @"Option2", nil]; [alert show]; } -

问题 I've just discovered VBScript's GetRef function, which gets a reference to the function named by its argument. Is there any way to get a reference to a method in this way? I have a hunch that VBScript doesn't offer the sophistication of binding needed to do so, but it would sure be nice. 回答1: No, GetRef doesn't support class methods. 回答2: There is a workaround for this, see my answer here Here the full sample Const forReading = 1, forWriting = 2, forAppending = 8, CreateFile = True Set my_obj

问题 I have a class with a protected method Zig::punt() and I only want it to be accessible to the class "Avocado". In C++, you'll normally do this using the "friend Avocado" specifier, but this will cause all of the other variables to become accessible to "Avocado" class; I don't want this because this breaks encapsulation. Is what I want impossible, or does there already exist an obscure trick out there that I can use to achieve what I want? Or possibly alternative class design patterns that'll
