explicit

问题 Here's the story. I created an interface, IVehicle . I explicitly implemented the interface in my class, Vehicle.cs . Here is my interface: Interface IVehicle { int getWheel(); } here is my class: class Vehicle: IVehicle { public int IVehicle.getWheel() { return wheel; } public void printWheel() { Console.WriteLine(getWheel()); } } Notice that getWheel() is explicitly implemented. Now, when I try to call that method within my Vehicle class, I receive an error indicating that getWheel() does

问题 I have extended std::string to fulfil my needs of having to write custom function build into string class called CustomString I have defined constructors: class CustomString : public std::string { public: explicit CustomString(void); explicit CustomString(const std::string& str); explicit CustomString(const CustomString& customString); //assignment operator CustomString& operator=(const CustomString& customString); ... }; In the third constructor (copy constructor) and assignment operator,

问题 What are the types of waits present in the Explicit Wait in Selenium webdriver (Java)? Is there any types in Explicit Wait? if so please elaborate.. 回答1: There are following waits: FluentWait This is special wait where You can set time to wait for a certain condition, as well as the frequency with which to check the condition like eg. wait for 10s and check every 1s, and ignore "NoSuchElementExceptions" exception, if You anticipate that this exception will happen for some time Wait wait = new

问题 I have a method that effectively takes a string. However, there is a very limited subset of strings I want to use. I was thinking of typedef'ing std::string as some class, and call the functions explicit. I'm not sure that would work, however. Ideas? 回答1: The usual rule still applies: the class isn't designed to be inherited from, and its destructor isn't virtual, so if you ever upcast to the std::string base class, and let the object be destroyed, your derived class' destructor won't be

问题 I am trying to convert c# code into c++/cli. Everything went smoothly until i started translating interface event explicit implementations into c++/cli syntax. Let's say in c# i have this interface public interface Interface { public event MyEventHandler Event; } Which is implemented in Class in explicit way, so it doesn't conflict with another member by its name: public interface Class : Interface { event MyEventHandler Interface.Event; public event AnotherEventHandler Event; } I am trying

问题 class Test { public: Test(int i) { cout<<"constructor called\n";} Test(const Test& t) { cout<<" copy constructor called\n";} }; class Test1 { public: Test1(int i) { cout<<"constructor called\n";} explicit Test1(const Test1& t) { cout<<" copy constructor called\n";} }; int main() { Test t(0); Test u = 0; //Test1 t1(0); Line 1 //Test1 u1 = 0; Line 2 } I observe different outputs. Case 1: When Line 1 and Line 2 are commented the o/p is : constructor called constructor called Case 2: When Line 1

问题 My explicit wait isn't waiting until the element is present. It literally waits the amount of seconds I declared and then the tests still fails. If I place a implicit wait in the exact same place the test passes. From what I'm reading, it's best practise to avoid implicit waits as much as possible. Am I doing something wrong? I have made a method in the base_page like so: def _wait_for_is_displayed(self, locator, timeout): try: wait = WebDriverWait(self.driver, timeout) wait.until(expected

问题 In a header file (which I haven't written), a struct has been defined like this struct MemoryMessage : public boost::counted_base { /*, public FastAlloc*/ explicit MemoryMessage(MemoryMessageType aType) : theType(aType) {} explicit MemoryMessage(MemoryMessageType aType, MemoryAddress anAddress) : theType(aType) {} explicit MemoryMessage(MemoryMessageType aType, MemoryAddress anAddress, int anIdentifier) : theType(aType) {} explicit MemoryMessage(MemoryMessageType aType, MemoryAddress
