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.

Synopsis
#include <rw/tvmap.h>
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.
Example
#include <iostream>
#include <functional>
#include <rw/tvmap.h>
#include <rw/cstring.h>
#include <rw/tools/datetime.h>
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;
}

template<typename P >
iterator RWTValMap< K, T, C, A >::insert ( iterator  hint,
P &&  val 
)
inline

Attempts to insert val into self. If an existing item with an equivalent key is already in the collection, val is not inserted, and an iterator to the existing item is returned. Otherwise inserts val and returns an iterator to the new item.

The hint parameter indicates where in the collection the new value should be inserted. This value is only a hint, and will be ignored if the value should be inserted at a different location according to the container's comparison object.

Condition:
This method is available only on platforms with rvalue reference support.

P is a type that is convertible to value_type.
