Detailed Description

template<class N, class I, class K = I>
class DDI::Store< N, I, K >

A Store provides a place for objects of type I which are uniquely identified by there name of type N. The objects themselves can be accessed indirectly by the prep_type of the Store like

typedef Store<std::string,double> NamedDouble; NamedDouble::prep_type d = NamedDouble("Four", new double(4.)); double val = *(d->second); std::string name = d->first;

K is the key_type which is used as an index in the storage. It must fulfill all requirements for a key in a sorted associative container. N is the user-friendly name_type, which must be mapped uniquely to the key_type and vice versa. N itself must also fulfill all requirements of a key in a sorted associative container. The reason to provide K is that one might save some memory by compacting common parts of information contained in different instances of N, e.g. if N is a pair<string,string>, the first string being a 'namespace' the second a 'name' then K could be a pair<int,string> thus compacting the namespace-string to a simple int. K and N must support following unique conversions:

• from N to K, thus N(const K &)
• from K to N, thus K(const N &)
