Detailed Description

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

which 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.

RWTPtrSet will not accept an item that compares equal to an item already in the collection. (RWTPtrMultiSet may contain multiple items that compare equal to each other.) Equality is based on the comparison object and not on the == operator. Given a comparison object comp, items 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/tpset.h>
RWTPtrSet<T, C, A> s;

See also

Class RWTPtrMultiSet offers the same interface to a pointer-based collection that accepts multiple items that compare equal to each other. RWTPtrMap is a pointer-based collection of key-value pairs.

Class std::set<T*,key_compare,A > is the C++ Standard collection that serves as the underlying implementation for RWTPtrSet.

Example

#include <functional>
#include <iostream>
 
#include <rw/cstring.h>
#include <rw/tpset.h>
 
int main() {
  RWTPtrSet<RWCString, std::less<RWCString> > set;
 
  set.insert(new RWCString("one"));
  set.insert(new RWCString("two"));
  set.insert(new RWCString("three"));
 
  RWCString* entry = new RWCString("one");
  if (!set.insert(entry))  // Rejected: duplicate entry
  {
    delete entry;
  }
 
  std::cout << set.entries() << std::endl;  // Prints "3"
  set.clearAndDestroy();
  std::cout << set.entries() << std::endl;  // Prints "0"
 
  return 0;
}

Program output:

const_reverse_iterator RWTPtrSet< T, C, A >::rbegin ( ) const

inline

Returns an iterator referring to the last element in the container.

If the container is empty, returns rend().

remove() [1/2]

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

value_type RWTPtrSet< T, C, A >::remove ( bool(* fn )(const T *, void *), void * d )

inline

Removes and returns the first element t in self such that the expression ((*fn)(t,d)) is true. Returns rwnil if there is no such element. Client data may be passed through parameter d.

remove() [2/2]

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

value_type RWTPtrSet< T, C, A >::remove ( const T * a )

removeAll() [1/2]

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

size_type RWTPtrSet< T, C, A >::removeAll	(	bool(*	fn )(const T *, void *),

removeAll() [2/2]

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

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

inline

rend() [1/2]

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

reverse_iterator RWTPtrSet< 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.

rend() [2/2]

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

const_reverse_iterator RWTPtrSet< 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.

std() [1/2]

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

inline

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

std() [2/2]

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

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

inline

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

swap()

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

void RWTPtrSet< T, C, A >::swap ( RWTPtrSet< 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.

symmetricDifference()

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

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

inline

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

Union()

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

void RWTPtrSet< T, C, A >::Union ( const RWTPtrSet< 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.
