arielm / Boost.bimap key copying test

Created January 14, 2014 10:54

I'm using Boost.bimap for implementing a LRU cache with some "complex key" containing a string. The problem is that the key is copied every-time I'm invoking find(). I would like to avoid this un-necessary copy (and in general: make as few as possible copies of the string, maybe via templates?)

	#include <string>
	#include <iostream>

	#include <boost/bimap.hpp>
	#include <boost/bimap/list_of.hpp>
	#include <boost/bimap/set_of.hpp>

	class Test
	{
	public:

arielm / std::map key copy test

Last active January 3, 2016 04:49

Checking how many copies are taking place when using complex keys for maps: 1. The keys are created once, and then copied when inserted into the map. 2. The keys are not copied when std::map::find is invoked (unlike, apparently, when using Boost.bimap...)

	#include <string>
	#include <tuple>
	#include <iostream>

	struct TestObject
	{
	std::string s;
	int i;

	TestObject(const std::string &s, int i)

arielm / std::tie copy test

Last active January 3, 2016 04:39

Checking if object copying is taking place each time std::tie is called. The answer: TestObject is not copied. Good news, say, if we want to use std::tie for maps (with complex keys...)

	#include <string>
	#include <tuple>
	#include <iostream>

	struct TestObject
	{
	std::string s;
	int i;

	TestObject(const std::string &s, int i)
