Detailed Description

An integer Vector in SpaceDim-dimensional space.

The class IntVect is an implementation of an integer vector in a SpaceDim-dimensional space. It represents a point in a discrete space. IntVect 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.
