Detailed Description

template<class Key, class Object, class Factory = DefaultSingletonFactory< Key, Object >>
class Dune::Fem::SingletonList< Key, Object, Factory >

Singleton list for key/object pairs.

A singleton list guarantees that for any valid key at most one object is created.

Parameters

Key	type of keys
Object	type of objects
Factory	factory class creating objects from keys. The default just passes the key to the object's constructor.

getObject()

template<class Key , class Object , class Factory = DefaultSingletonFactory< Key, Object >>

template<class... Args>

static auto Dune::Fem::SingletonList< Key, Object, Factory >::getObject ( const KeyType &  key, Args &&...  args  ) -> std::enable_if_t< std::is_same< decltype( FactoryType::createObject( key, std::forward< Args >( args )... ) ), ObjectType * >::value, ObjectType & >

return reference to the object for given key. If the object does not exist, then it is created first, otherwise the reference counter is increased.
