Detailed Description
template<class T>
class Faunus::ElasticRange< T >
Turns a pair of iterators into an elastic range.
The elastic range is a range where elements can be deactivated and later activated without inserting/erasing:
- Just deactivated elements are moved to
end()and can be retrieved from there. - Just activated elements are placed at
end()-n. - The true size is given by
capacity()

◆ numInactive()
template<class T >
| auto Faunus::ElasticRange< T >::numInactive | ( | ) | const |
Number of inactive elements.
Determines if the given number (positive or negative) of particles can be inserted or deleted
