By Matthew Wilson, December 01, 2005
When an adapter template makes demands that a potential underlying type cannot fulfill, Interred Interface Adaptation can expand the number of adaptable types.

Listing 2

: m_current(c.begin())
, m_end(c.end())

public:
reference current()
{

}
bool is_open() const
{
return m_current != m_end;
}
void advance()
