Detailed Description

template<class... Args>
class tinympl::map< Args >

A compile time map from a type to another This class represents a compile time mapping between types. The mapping is specified using std::pair, that is every parameter of map must be an std::pair<KeyType,ValueType>.

map supports standard insertion/removal and element access.

Note

equal_to is specialized for map, in order to make the order in which the key/value pairs are specified irrelevant.

template<class... Args>

template<class Key >

using tinympl::map< Args >::count = std::integral_constant< std::size_t, (variadic::find<Key, typename Args::first_type ... >::type::value == size ? 0 : 1)>

Count the number of elements in the map with a given key.

Note

Since this class is a map and not a multimap, the only possible results for this operation are 0 and 1.
