A container is an STL template class that manages a sequence of elements. Such elements can be of any object type that supplies a copy constructor, a destructor, and an assignment operator. The destructor may not throw an exception. This document describes the properties required of all such containers, in terms of a generic template class container. An actual container template class may have additional template parameters. It will certainly have additional member functions.
The STL template container classes are:
The four hash containers are not required by the C++ Standard. The Standard C++ Library template class basic_string also meets the requirements for a template container class.
namespace std
{
template<class Ty>
class Container;
// TEMPLATE FUNCTIONS
template<class Ty>
bool operator==(
const Container<Ty>& left,
const Container<Ty>& right);
template<class Ty>
bool operator!=(
const Container<Ty>& left,
const Container<Ty>& right);
template<class Ty>
bool operator<(
const Container<Ty>& left,
const Container<Ty>& right);
template<class Ty>
bool operator>(
const Container<Ty>& left,
const Container<Ty>& right);
template<class Ty>
bool operator<=(
const Container<Ty>& left,
const Container<Ty>& right);
template<class Ty>
bool operator>=(
const Container<Ty>& left,
const Container<Ty>& right);
template<class Ty>
void swap(
Container<Ty>& left,
Container<Ty>& right);
};
