Detailed Description

template<class JElement_t, class JDistance_t = JDistance<typename JElement_t::abscissa_type>>
class JTOOLS::JGridCollection< JElement_t, JDistance_t >

General purpose class for collection of equidistant elements.

For a collection with equidistant elements, the index of the nearest element can directly be computed based on the minimal abscissa value, the maximal abscissa value and the number of elements in the collection. The lower_bound methods are re-implemented in this class which otherwise simply derives from JCollection.

For convenience, the implementation of the standard map operator [] of the JCollection class is maintained.
