Detailed Description

template<class T>
class Point2D< T >

This is a basic class to encode 2D integer coordinates.

This is a completely public class whose goal is just to provide a shorthand notation for 2D integer coordinates.

Constructor & Destructor Documentation

Point2D() [1/3]

template<class T >

Point2D< T >::Point2D ( )

inline

The default constructor initializes the coordinates to (0,0)

Definition at line 208 of file Point2D.H.

Point2D() [2/3]

template<class T >

Point2D< T >::Point2D ( const T  ii, const T  jj  )

inline

Initialize the Point2D from horizontal & vertical coordinates.

Definition at line 213 of file Point2D.H.

Point2D() [3/3]

template<class T >

template<class U >

Point2D< T >::Point2D ( const Point2D< U > &  a )

inlineexplicit

Explicit conversion from type T to another type U.

Note that this simply uses clamped_convert, so it will clamp coordinates to the available range of T, and may round down.
