Header: #include <UniginePair.h>

A pair container template. The class has the first and the second members that allow access to the corresponding elements of the pair.

Pair Class

Members


Pair ( ) #

Default constructor that produces an empty pair.

Pair ( const TypeFirst& f, const TypeSecond& s ) #

Constructor. Creates a pair of given elements.

Arguments

  • const TypeFirst& f - First pair element.
  • const TypeSecond& s - Second pair element.

void Pair ( const Pair<OtherFirst,OtherSecond>& o ) #

Replaces the pair with a given one.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

void Pair ( Pair<OtherFirst,OtherSecond>& o ) #

Replaces the pair with a given one.

Arguments

  • Pair<OtherFirst,OtherSecond>& o - Pair.

void Pair ( OtherFirst&& f, OtherSecond&& s ) #

Replaces the pair elements with given ones.

Arguments

  • OtherFirst&& f - First pair element.
  • OtherSecond&& s - Second pair element.

Pair<TypeFirst, TypeSecond> & operator= ( Pair<OtherFirst,OtherSecond>& o ) #

Assignment operator for the pair.

Arguments

  • Pair<OtherFirst,OtherSecond>& o - Pair to be assigned.

void swap ( Pair& o ) #

Swaps two pairs.

Arguments

  • Pair& o - Pair to swap.

bool operator== ( const Pair<OtherFirst,OtherSecond>& o ) const#

Checks if both elements of pairs are equal.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

Return value

Returns 1 if pairs are equal; otherwise, 0 is returned.

bool operator!= ( const Pair<OtherFirst,OtherSecond>& o ) const#

Checks if two pairs are not equal.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

Return value

Returns 1 if pairs are not equal; otherwise, 0 is returned.

bool operator< ( const Pair<OtherFirst,OtherSecond>& o ) const#

Checks if the pair is less than a given one: compares the first elements and only if they are equal, compares the second elements.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

Return value

Returns 1 if the pair is less than a given one; otherwise, 0 is returned.

bool operator> ( const Pair<OtherFirst,OtherSecond>& o ) const#

Checks if the pair is greater than a given one: compares the first elements and only if they are equal, compares the second elements.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

Return value

Returns 1 if the pair is greater than a given one; otherwise, 0 is returned.

bool operator<= ( const Pair<OtherFirst,OtherSecond>& o ) const#

Checks if the pair is less than or equal to a given one: compares the first elements and if they are equal, compares the second elements.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

Return value

Returns 1 if the pair is less than or equal to a given one; otherwise, 0 is returned.

bool operator>= ( const Pair<OtherFirst,OtherSecond>& o ) const#

Checks if the pair is greater than or equal to a given one: compares the first elements and if they are equal, compares the second elements.

Arguments

  • const Pair<OtherFirst,OtherSecond>& o - Pair.

Return value

Returns 1 if the pair is greater than or equal to a given one; otherwise, 0 is returned.
