Detailed Description

template<class T, class C = std::less<T>, class A = std::allocator<T*>>
class RWTPtrMultiSet< T, C, A >

This class maintains a pointer-based collection of values, which are ordered according to a comparison object of type C. 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.

C must induce a total ordering on elements of type T via a public member

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

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

RWTPtrMultiSet may contain multiple items that compare equal to each other. (RWTPtrSet will not accept an item that compares equal to an item already in the collection.)

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

Synopsis

#include <rw/tpmset.h>
RWTPtrMultiSet<T,C,A> s;

See also

Class RWTPtrSet offers the same interface to a pointer-based collection that will not accept multiple items that compare equal to each other. RWTPtrMultiMap maintains a pointer-based collection of key-value pairs.

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

Persistence

Isomorphic.

Example

// tpmset.cpp
//
#include <rw/tpmset.h>
#include <rw/cstring.h>
#include <iostream.h>
#include <functional>
int main(){
  RWTPtrMultiSet<RWCString, std::less<RWCString> > set;
  set.insert(new RWCString("one"));
  set.insert(new RWCString("two"));
  set.insert(new RWCString("three"));
  set.insert(new RWCString("one"));    // OK: duplicates allowed
  std::cout << set.entries() << std::endl;       // Prints "4"
  set.clearAndDestroy();
  std::cout << set.entries() << std::endl;       // Prints "0"
  return 0;
}

Program output:

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

size_type RWTPtrMultiSet< T, C, A >::removeAll ( const T *  a )

inline

Removes all elements t in self that compare equal to *a. Returns the number of items removed.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

reverse_iterator RWTPtrMultiSet< T, C, A >::rend ( )

inline

Returns an iterator referring to the element before the first element in the container.

Dereferencing the iterator returned by this function results in undefined behavior.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

const_reverse_iterator RWTPtrMultiSet< T, C, A >::rend ( ) const

inline

Returns an iterator referring to the element before the first element in the container.

Dereferencing the iterator returned by this function results in undefined behavior.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

container_type& RWTPtrMultiSet< T, C, A >::std ( )

inline

Returns a reference to the underlying C++ Standard Library collection that serves as the implementation for self.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

const container_type& RWTPtrMultiSet< T, C, A >::std ( ) const

inline

Returns a reference to the underlying C++ Standard Library collection that serves as the implementation for self.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

void RWTPtrMultiSet< T, C, A >::swap ( RWTPtrMultiSet< T, C, A > &  other )

inline

Swaps the data held by self with the data held by other, including the T and EQ objects. This method does not copy or destroy any of the items swapped; rather, it swaps the underlying hash tables.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

void RWTPtrMultiSet< T, C, A >::symmetricDifference ( const RWTPtrMultiSet< T, C, A > &  s )

inline

Sets self to the symmetric difference of self and s. Elements from each set are dereferenced before being compared.

template<class T, class C = std::less<T>, class A = std::allocator<T*>>

void RWTPtrMultiSet< T, C, A >::Union ( const RWTPtrMultiSet< T, C, A > &  s )

inline

Sets self to the union of self and s. Elements from each set are dereferenced before being compared.

Note

The uppercase "U" in Union avoids conflict with the C++ reserved word.

bool operator== ( const RWTPtrMultiSet< T, C, A > &  lhs, const RWTPtrMultiSet< T, C, A > &  rhs  )

related

Returns true if lhs and rhs are equal, otherwise false. Two collections are equal if both have the same number of entries, and iterating through both collections produces individual elements that, in turn, compare equal to each other. Elements are dereferenced before being compared.

Looks at the next object on the input stream strm and either creates a new collection off the heap and sets p to point to it, or sets p to point to a previously read instance. If a collection is created off the heap, then the application is responsible for deleting it.
