Stuff about C++11 that I like... #2 Delegating Constructors

photopin cc

Delegating constructors is cool.

TL;DR With C++11 you can kiss goodbye to some 'init' method function shared between constructors or copying and pasting between your constructors.

Like inherited constructors I like delegating constructors[1] too - it's intuitive and clear:

	template<typename T>
	class worker {
	public:
	enum states {WAITING, RUNNABLE, STEALING, TERMINATED};
	// default runnable start state is C++11 delegated to the general purpose constructor
	worker(std::vector<T>& queues): worker(queues, RUNNABLE) {}
	worker(std::vector<T>& queues, states state): this_id(count++), state(state), queues(queues) {
	//do shared intialization stuff
	}
	.
	.
	.
