Detailed Description

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
class RWTValMap< K, T, C, A >

This class maintains a collection of keys, each with an associated item of type T. Class A is an allocator of objects of class T. For more information about using custom allocators, please see the Essential Tools Module User's Guide.

Order is determined by the key according to a comparison object of type C. C must induce a total ordering on elements of type K via a public member:

bool operator()(const K& x, const K& y) const

which returns true if x and its associated object should precede y and its associated object within the collection. The structure std::less<T> from the C++ Standard Library header file <functional> is an example of such a comparison object.

Equality is based on the comparison object and not on operator==(). Given a comparison object comp, keys a and b are equal if !comp(a,b) && !comp(b,a).

The value type must have operator==() and operator<() defined. This requirement is imposed by the C++ Standard Library.

Definition tvmap.h:129
See also

Class RWTValMultiMap offers the same interface to a collection that accepts multiple keys that compare equal to each other. RWTValSet maintains a collection of keys without the associated values.

Class std::map<K,T,C,A> is the C++ Standard Library collection that serves as the underlying implementation for this class.

Persistence
Isomorphic.

#include <iostream>
int main() {
birthdays.insert("John",
RWDateTime("April 12, 1975", RWDateTime::setDate));
birthdays.insert("Ivan",
RWDateTime("Nov 2, 1980", RWDateTime::setDate));
// Alternative syntax:
birthdays["Susan"] = RWDateTime("June 30, 1955", RWDateTime::setDate);
birthdays["Gene"] = RWDateTime("Jan 5, 1981", RWDateTime::setDate);
// Print a birthday:
std::cout << birthdays["John"].asString('x') << std::endl;
return 0;
}
Represents a date and time stored in milliseconds.

inline
