Detailed Description

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

This class maintains a pointer-based collection of values, which 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 T and returns a value of type size_t.

Equivalent elements 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 T and returns a value of type bool.

Note

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

This class allows multiple items that are equivalent to each other. Use RWTPtrHashSet if you need a class that does not allow equivalent values.

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

Synopsis

#include <rw/tphasht.h>
RWTPtrHashMultiSet<T,H,EQ,A> hmset;

See also

Class RWTPtrHashSet offers the same interface to a pointer-based collection that does not allow multiple items that compare equal to each other.

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

Example

//
// tphmset.cpp
//
#include <iostream>
#include <functional>
#include <rw/tphasht.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 ()
{
    RWTPtrHashMultiSet<RWCString,simple_hash,std::equal_to<RWCString> > set1;
    RWTPtrHashMultiSet<RWCString,simple_hash,std::equal_to<RWCString> > set2;

    set1.insert(new RWCString("one"));
    set1.insert(new RWCString("two"));
    set1.insert(new RWCString("three"));
    set1.insert(new RWCString("one"));    // OK: duplicates allowed

    std::cout << set1.entries() << "\n";  // Prints "4"

    set2 = set1;
    std::cout << ((set1.isEquivalent(set2)) ? "true" : "false") << "\n";
    // Prints "true"

    set2.difference(set1);

    set1.clearAndDestroy();
    std::cout << set1.entries() << "\n"; // Prints "0"
    std::cout << set2.entries() << "\n"; // Prints "0"

    return 0;
}

Program output:
