Detailed Description

template<int dim>
class amrex::IntVectND< dim >

An Integer Vector in dim-Dimensional Space.

The class IntVectND is an implementation of an integer vector in a dim-dimensional space. It represents a point in a discrete space. IntVectND values are accessed using the operator[] function, as for a normal C++ array. In addition, the basic arithmetic operators have been overloaded to implement scaling and translation operations.
