Detailed Description

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

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.

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

Synopsis

#include <rw/tvhasht.h>
RWTValHashMultiSet<T, H, EQ, A> m;

See also

Class RWTValHashSet offers the same interface to a collection that does not accept multiple items that compare equal to each other.

Class rw_hashmultiset<T,H,EQ,A> is the C++ Standard Library collection class that serves as the underlying implementation for RWTValHashMultiSet.

Example

#include <functional>
#include <iostream>
 
#include <rw/cstring.h>
#include <rw/tvhasht.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() {
  RWTValHashMultiSet<RWCString, simple_hash, std::equal_to<RWCString> >
      set1;
  RWTValHashMultiSet<RWCString, simple_hash, std::equal_to<RWCString> >
      set2;
 
  set1.insert("one");
  set1.insert("two");
  set1.insert("three");
  set1.insert("one");  // OK: duplicates allowed
  set1.insert("one");
 
  std::cout << set1.entries() << std::endl;  // Prints "5"
 
  set2.insert("one");
  set2.insert("five");
  set2.insert("one");
 
  std::cout << ((set1.isEquivalent(set2)) ? "true" : "false")
            << std::endl;
  // Prints "false"

  set1.clear();
 
  std::cout << set1.entries() << std::endl;  // Prints "0"
  std::cout << set2.entries() << std::endl;  // Prints "2"
 
  return 0;

bool RWTValHashMultiSet< T, H, EQ, A >::remove ( bool(* fn )(const_reference, void *), void * d )

inline

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

size_type RWTValHashMultiSet< T, H, EQ, A >::removeAll	(	bool(*	fn )(const_reference, void *),
		void *	d )

Removes all elements t in self such that the expression ((*fn)(a,d)) is true. Returns the number of items removed. Client data may be passed through parameter d.

removeAll() [2/2]

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

size_type RWTValHashMultiSet< T, H, EQ, A >::removeAll ( const value_type & a )

inline

resize()

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

void RWTValHashMultiSet< T, H, EQ, A >::resize ( size_type sz )

inline

Changes the capacity of self by creating a new hashed multi-set with a capacity of sz. resize() copies every element of self into the new container and finally swaps the internal representation of the new container with the internal representation of self.

std() [1/2]

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

container_type & RWTValHashMultiSet< T, H, EQ, A >::std ( )

inline

Returns a reference to the underlying collection that serves as the implementation for self. This reference may be used freely, providing access to the C++ Standard Library interface as well as interoperability with other software components that make use of the C++ Standard Library collections.

std() [2/2]

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

const container_type & RWTValHashMultiSet< T, H, EQ, A >::std ( ) const

inline

Returns a reference to the underlying collection that serves as the implementation for self. This reference may be used freely, providing access to the C++ Standard Library interface as well as interoperability with other software components that make use of the C++ Standard Library collections.

swap()

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

void RWTValHashMultiSet< T, H, EQ, A >::swap ( RWTValHashMultiSet< T, H, EQ, A > & other )

inline

Swaps the data held by self with the data held by other, including the H 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 H = RWTHash<T>, class EQ = std::equal_to<T>, class A = std::allocator<T>>

void RWTValHashMultiSet< T, H, EQ, A >::symmetricDifference ( const RWTValHashMultiSet< T, H, EQ, A > & s )

inline

Destructively performs a set-theoretic symmetric difference operation on self and s. Self is replaced by the result. A symmetric difference can be informally defined as \((A \cup B) \setminus (A \cap B)\).

Union()

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

void RWTValHashMultiSet< T, H, EQ, A >::Union ( const RWTValHashMultiSet< T, H, EQ, A > & rhs )

inline

Destructively performs a set-theoretic union operation on self and rhs. Self is replaced by the result. Note the uppercase 'U' in Union to avoid conflict with the C++ reserved word.
