Detailed Description

template<class T>
struct evo::CompareR< T >

Comparison object used with containers that order/sort items (reverse).

• This produces a descending (reversed) sort order
• POD and Byte-Copy types are compared directly
• Normal class types are compared by calling method: T::compare()
  • Evo types like String implement this compare() method
  • See IsNormalType, TypeId
• See: Compare, CompareI, CompareIR

Template Parameters
