Constructor & Destructor Documentation

virtual lsst::afw::math::Interpolate::~Interpolate ( )

Definition at line 54 of file Interpolate.h.

{}

lsst::afw::math::Interpolate::Interpolate ( std::vector< double > const &  x, std::vector< double > const &  y, Interpolate::Style const  style = UNKNOWN  )

inlineprotected

Base class ctor

Parameters

x	the ordinates of points
y	the values at x[]
style	desired interpolator

Definition at line 60 of file Interpolate.h.

                 : _x(x), _y(y), _style(style) {}

lsst::afw::math::Interpolate::Interpolate ( std::pair< std::vector< double >, std::vector< double > > const  xy, Interpolate::Style const  style = UNKNOWN  )

protected

Base class ctor. Note that we should use rvalue references when available as the vectors in xy will typically be movable (although the returned-value-optimisation might suffice for the cases we care about)

Note

this is here, not in the .h file, so as to permit the compiler to avoid copying those vectors

Parameters

xy	pair (x,y) where
style	x are the ordinates of points and y are the values at x[] desired interpolator

Definition at line 343 of file Interpolate.cc.

                          : _x(xy.first), _y(xy.second), _style(style)
{
    ;
