Member Function Documentation

template<class _ContainerType >

virtual interpolated inet::physicallayer::Nearest< _ContainerType >::operator() ( const const_iterator &  first, const const_iterator &  last, key_cref_type  pos, const_iterator  upperBound  ) const

inlinevirtual

Functor operator of this class which interpolates the value at the passed position using the values between the passed Iterators.

The upperBound-iterator has to point two the entry next bigger as the passed position to interpolate.

The returned instance of interpolated represents the result. Which can be either an actual entry of the interpolated map (if the position to interpolate was exactly that. Or it can be an interpolated value, if the passed position was between two entries of the map. This state can be retrieved with the "isInterpolated"-Member of the returned "interpolated".

Returns

The value of a element between first and last which is nearest to pos.

Implements inet::physicallayer::InterpolatorBase< _ContainerType >.
