Detailed Description

template<class C>
class elm::StrictMapDelegate< C >

Delegate class to access functions get/put() of map using the overload of [i] operators. In the opposite to MapDelegate, this class throws a KeyException if the key of a read item does not exist.

A common use of this delegate in a class implementing a mutable map:

template <class K, class T>
class MyMap {
public:
 typedef K key_t;
 typedef T val_t;
    ...
 inline StricMapDelegate<MyMap> operator[](const K& k)
    { return StrictMapDelegate<MyMap>(*this, k); }
 ...
};

Parameters

T	Type of map element values.
