Detailed Description

template<typename DataT>
class Nektar::LibUtilities::Points< DataT >

Stores a set of points of datatype DataT, defined by a PointKey.

This encapsulates a set of points, specified by a PointKey. The class stores not only the point coordinates, but also the integration weights and derivative matrix coefficients. Memory is allocated from the memory pool if in use.
