Detailed Description

template<class K, class T, class C, class A = std:: allocator < std::pair<K* const, T*> >>
class RWTPtrMultiMap< K, T, C, A >

This class maintains a pointer-based collection of associations of type pair<K*, const T*>. The first part of the association is a key of type K*, the second is its 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)

which returns true if x and its partner should precede y and its partner within the collection. The structure std::less<T> from the C++ Standard Library header file <functional> is an example. Note that keys will be dereferenced before being compared.

RWTPtrMultiMap<K,T,C,A> may contain multiple keys that compare equal to each other. (RWTPtrMap<K,T,C,A> will not accept a key that compares equal to any key already in the collection.) Equality is based on the comparison object and not on the == 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/tpmmap.h>
 RWTPtrMultiMap<K,T,C,A>  m;

Related Classes

Class RWTPtrMap<K,T,C,A> offers the same interface to a pointer-based collection that will not accept multiple keys that compare equal to each other. RWTPtrMultiSet<T,C,A> maintains a pointer-based collection of keys without the associated values.

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