Constructor & Destructor Documentation

FourthOrderFineInterp::FourthOrderFineInterp (  ) 

Default constructor.

Object requires define() to be called before all other functions.

FourthOrderFineInterp::~FourthOrderFineInterp (  ) 

Destructor.

Destroys all objects created by define(). Passed in data references of define() are left alone.

FourthOrderFineInterp::FourthOrderFineInterp ( const FourthOrderFineInterp a_input  )  [inline, private]
