  • C++, What does the colon after a constructor mean?
    It's called an initialization list An initializer list is how you pass arguments to your member variables' constructors and for passing arguments to the parent class's constructor If you use = to assign in the constructor body, first the default constructor is called, then the assignment operator is called This is a bit wasteful, and
  • How can I invoke asynchronous code within a constructor?
    The constructor() can then trigger the async creation of the properties, but the getter then checks to see if the property is available before it uses or returns it This approach is particularly useful when you want to initialize a global object once on startup, and you want to do it inside a module
  • Can an abstract class have a constructor? - Stack Overflow
    You would provide a constructor for an abstract class if you want to initialise certain fields of the abstract class before the instantiation of a child-class takes place An abstract class constructor can also be used to execute code that is relevant for every child class This prevents code duplication
  • Constructor overload in TypeScript - Stack Overflow
    Your Box class is attempting to define multiple constructor implementations Only the last constructor overload signature is used as the class constructor implementation In the below example, note the constructor implementation is defined such that it does not contradict either of the preceding overload signatures

    If you simply want to pass all constructor arguments to the base-class (=parent), here is a minimal example This uses templates to forward every constructor call with 1, 2 or 3 arguments to the parent class std::string Code Live-Version
  • c# - Can constructors be async? - Stack Overflow
    Constructor acts very similarly to a method returning the constructed type And async method can't return just any type, it has to be either “fire and forget” void, or Task If the constructor of type T actually returned Task<T>, that would be very confusing, I think
  • Whats the difference between an object initializer and a constructor?
    A constructor is a defined method on a type which takes a specified number of parameters and is used to create and initialize an object An object initializer is code that runs on an object after a constructor and can be used to succinctly set any number of fields on the object to specified values
