Standard C++ Library Reference ISO/IEC (VERSION3)

map::operator[]
Ty& operator[](const Key& keyval);
The member function determines the iterator where as the return value of insert(
value_type(keyval, Ty()). (It inserts an element with the specified key if no such
element exists.) It then returns a reference to (*where).second.
map::pointer
typedef Alloc::pointer pointer;
The type describes an object that can serve as a pointer to an element of the controlled
sequence.
map::rbegin
const_reverse_iterator rbegin() const;
reverse_iterator rbegin();
The member function returns a reverse bidirectional iterator that points just beyond the end of
the controlled sequence. Hence, it designates the beginning of the reverse sequence.
map::reference
typedef Alloc::reference reference;
The type describes an object that can serve as a reference to an element of the controlled
sequence.
map::rend
const_reverse_iterator rend() const;
reverse_iterator rend();
The member function returns a reverse bidirectional iterator that points at the first element of
the sequence (or just beyond the end of an empty sequence). Hence, it designates the end of the
reverse sequence.
map::reverse_iterator
typedef reverse_iterator<iterator> reverse_iterator;
The type describes an object that can serve as a reverse bidirectional iterator for the controlled
sequence.
