I have the following global variable: private Map<String,List<String>> network; I instantiate it in my constructor like this:
I\'m in the process of learning Haskell, and type classes seem like a powerful way to make type-safe polymorphic functions. But a lot of the Haskell Prelude functions don\'t use them.More specifically
I\'ve been reviewing the draft version of the C++11 standard. Specifically the section on lambdas, and I am confused as to the reasoning for not introducing polymorphic lambdas.
I\'m having a problem in Java. I have a method that can be extended. The problem is, that this method calls other methods of the class, and these can be extended as well.
I am trying to create a Vector class that is generic for all numeric types. my original attempt was to write a class for all Types like this:
In Java what\'s the \"correct\" way to implement an interface where the parameters for a method need parametric polymor开发者_运维技巧phism?
Suppose I have the following classes: class BaseObject { public: virtual int getSomeCommonProperty(); }; class Object1: public BaseObject {
So as a class assignment I\'m reimplementing std::vector, and I\'m having trouble with declaring the prototype for:
Boost smart pointers can be used with polymorphism, but how do you cast the subclass back to the pointer?
Can boost::smart_ptr such as scoped_ptr and shared_ptr be used in std containers such as std::map? class SomeClass
