Detailed Description

template<class K, class T, class H = RWTHash<K>, class EQ = std::equal_to<K>, class A = std::allocator<K*>>
class RWTPtrHashMultiMap< K, T, H, EQ, A >

This class maintains a pointer-based collection of associations of type std::pair<K* const, T*>. These pairs are stored according to a hash object of type H. Class T is the type pointed to by the items in the collection. 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.

H must provide a const function that takes a single argument convertible to type K and returns a value of type size_t.

Equivalent keys within the collection are grouped together based on an equality object of type EQ. EQ must ensure this grouping via a function that takes two arguments convertible to type K and returns a value of type bool.

Note
Any two keys that are equivalent must hash to the same value.

This class allows multiple keys that are equivalent to each other. Use the class RWTPtrHashMap if you need a collection that does not accept duplicate keys. Equality is based on the comparison object and not on operator==().

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

Synopsis
#include <rw/tphmmap.h>
See also

Class RWTPtrHashMap offers the same interface to a pointer-based collection that does not accept multiple keys that compare equal to each other.

rw_hashmultimap<K*,T*,hasher,key_equal,A> is the C++ Standard Library-style collection that serves as the underlying implementation for this class.

Persistence
Isomorphic
Example
//
// tphmmap.cpp
//
#include <iostream>
#include <functional>
#include <rw/tphmmap.h>
#include <rw/cstring.h>
struct simple_hash
{
unsigned long
operator()(const RWCString& ref) const {
size_t n = ref.length ();
return (unsigned long)(n ? n * size_t (ref [0]) : 0);
}
};
int main ()
{
RWCString snd = "Second";
contest;
contest.insert(new RWCString("First"), new int(7));
contest.insert(&snd, new int(3));
contest.insert(&snd, new int(6)); // this contains two pointers to snd
contest.insert(new RWCString("Third"), new int(2));
std::cout << "There were " << contest.occurrencesOf(&snd)
<< " second place winners." << std::endl;
return 0;
}

Program Output:

There were 2 second place winners.

Inserts val into self. 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.

template<typename InputIterator >
void RWTPtrHashMultiMap< K, T, H, EQ, A >::insert ( InputIterator  first,
InputIterator  last 
)

Inserts the elements in the range [first, last) into self.

InputIterator is an input iterator type that points to elements that are convertible to value_type objects.

void RWTPtrHashMultiMap< K, T, H, EQ, A >::resize ( size_type  sz)
inline

Changes the capacity of self by creating a new hashed multi-map with a capacity of sz. The copies resize every association in self into the new container and finally swaps the internal representation of the new container with self.
