Function Documentation

template<class M >

M::mapped_type at	(	const M &	map,
		const typename M::key_type &	key
	)			[inline]

Emulation for C++11's std::map::at().

Acts like return map[key], but can be used on const map, and if the key doesn't exist will throw an exception instead of adding the key.

A non-official reference can be found here: http://en.cppreference.com/w/cpp/container/map/at

Note:

Didn't use template<class K, class V> since that has a problem when deducting the type when the key is a std::string and the type send is a charater string, e.g. "foo". Letting the map deduct the K and V types works.

Exceptions:

std::out_of_range

When the key is not in the map.

Parameters:

	map	The map search into.
	key	The key to search for.

Returns:

A copy of the value of key.

Note:

C++11 uses a reference, but it's not possible to create a reference from an iterator.
