Detailed Description

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

This class maintains a collection of values, which are ordered according to a comparison object of type C. Class T is the type of 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) const

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.

RWTValSet will not accept an item that compares equal to an item already in the collection. (RWTValMultiSet may contain multiple items that compare equal to each other.) Equality is based on the comparison object and not on 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/tvset.h>
RWTValSet<T, C, A> s;

See also

Class RWTValMultiSet offers the same interface to a collection that accepts multiple items that compare equal to each other. RWTValMap maintains a collection of key-value pairs.

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

Persistence

Isomorphic.

Example

#include <rw/cstring.h>
#include <rw/tvset.h>
#include <functional>
#include <iostream>
 
int main() {
  RWTValSet<RWCString, std::less<RWCString> > set;
  set.insert("one");
  set.insert("two");
  set.insert("three");
  set.insert("one");  // Rejected: already in collection
  std::cout << set.entries() << std::endl;  // Prints "3"
  return 0;
}

Program Output:

3

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.

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

inline

Sets self to the union of self and s.

Note

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