Constructor & Destructor Documentation

template<class _T1, class _T2> std::pair< _T1, _T2 >::pair () [inline]

The default constructor creates first and second using their respective default constructors.

Definition at line 80 of file stl_pair.h.

template<class _T1, class _T2> std::pair< _T1, _T2 >::pair (const _T1 & __a, const _T2 & __b) [inline]

Two objects may be passed to a pair constructor to be copied.

Definition at line 84 of file stl_pair.h.

template<class _T1, class _T2> template<class _U1 , class _U2 > std::pair< _T1, _T2 >::pair (const pair< _U1, _U2 > & __p) [inline]

There is also a templated copy ctor for the pair class itself.
