wrapper

问题 I've declared two aspects as foo & bar over a function runFunc and I want to capture time taken to run the function runcFunc & Bar in Foo , but it is capturing the time only for runFunc . Bar is running independently. I want that If I put two annotation over a function, the 1st annotation should wrap the 2nd annotation and the 2nd one should wrap the function runfunc . How can I achieve that? 回答1: It turns out aspect can wrap other aspects just as easily as they can wrap a function. Following

问题 What I want to do is to traverse the node in order, so that I can print the node in binary tree in order. void inorder_traverse(node* root, function<void(node*)> visit) { if (root == nullptr) return; cout << root->data << ", "; inorder_traverse(root->left, visit); visit(root); inorder_traverse(root->right, visit); } I saw this code for inorder traversing a binary tree. Traversing goes all the nodes so I thought I could print all the data of all visited nodes using traversing function. Would

问题 I have my own C++ library project(with source) written in Qt and it uses QTcpsocket , QUdpSocket , QSerialPort signals and slots. I would like to support this library in Python as well. What is the preferred way to do this? Writing a wrapper in Python, if so does it have obstacles? Dont know if PyQt is just for this purpose? Or do you thnink is it better to rewrite the lib in Python by just implementing the logic used in C++ library project. As this is library is part of a SDK, same applies

问题 Right, so, I've been self-editing a rather complicated site and have been stuck on this last part involving the menu. It has a float:left command (the navbar displays alined to the left of the screen) and I've been trying to get it to text-align:center (appear centered within the screen) with a wrapper but have been unsuccessful. Below is the coding: #nav a { display: block; padding: 5px; color: #aaa; text-decoration: none; outline: none; font-weight: normal; font-family: "Droid Serif",

问题 With Django models, I want to achieve this: class Foo(models.Model): name = models.CharField(max_length=50) #wrapping the save function, including extra tasks def save(self, *args, **kwargs): super(Foo, self).save(*args, **kwargs) if extra_param: ...do task 1 else: ...do task 2 And while crating Foo I want to pass such as Foo(name="Bill Gates",extra_param=True).save() # now triggers the task 1 Foo(name="Bill Gates").save() # now triggers the task 2 How can this be done? I am also open to any

问题 What's the usage of: https://docs.oracle.com/javase/7/docs/api/javax/xml/bind/annotation/XmlElementWrapper.html so that a "collection of collections" can be created programatically in a standards acceptable fashion?

问题 I have been tasked to create a C# interface with some of the methods that are being using in the Open Source CrytoLib C++ project. I am trying to create a managed wrapper for the LIB file... however I am getting some errors already and cannot figure out what I am doing wrong as this seems pretty straightforward to this point. My header file: // CryptoLibWrapper.h #pragma once using namespace System; namespace CryptoLibWrapper { public ref class DefaultDecryptorWithMAC { public: BOOL Decrypt

问题 I'm having sleeping issues because of this! I have a VS2005 C# DLL that should communicate to a USB device under Labview. The C# DLL is mounted over a C++ Wrapper who's over a C++ (unmanaged) Project (not coded by me, but I own the code. btw. C++ and me, we're not best friends). Using this wrapper I can (under Windows/Visual Studio) do everything (connect, disconnect, send and receive data). The problem occurs under Labview. It connects, disconnects, send files but it doesn't receives(not

问题 This question is in continuation to a question How can a string be initialized using " "? I would like to raise your attentation that even Integer , Double , Character , Float , Boolean wrapper class can also be declared in the same way String is declared like: String s = "Test string" Integer i = 10; //valid Double d = 10.00; //valid Boolean b = true; //valid Does these class are also given special treatment like the String class. 回答1: As I pointed out In my previous answer(How can a string

问题 This question already has answers here : Typescript typings, generics and abstract classes (2 answers) Closed 2 years ago . This is somewhat the transformation of a question I posted somewhere else yesterday. My objective is not to get a working result but to have a better understanding of the kind of design I can obtain while returning the correct types. This by using here a minimalist example, so please don't tell me it's useless or does nothing. Code sample (Try it in Typescript playground
