ArrayCore::FKHorizontal::FKHorizontal

(

QList< FKStationSignals * >

array

)

[protected]

Set array, indentify component index. Component must be either horizontal or vertical and horizontal. Called by FKRadial and FKTransverse

References _rotation.

  : FK(array)
{
  _rotation=0;
  setComponents(array.first()->nComponents());
}

ArrayCore::FKHorizontal::FKHorizontal	(	double	angle,
		QList< FKStationSignals * >	array
	)

Set array, indentify component index. Component must be either horizontal or vertical and horizontal. angle is in degrees from North clockwize.

References _rotation, QGpCoreTools::Angle::setDegreeAzimuth(), QGpCoreTools::Point2D::setX(), and QGpCoreTools::Point2D::setY().

  : FK(array)
{
  _rotation=0;
  setComponents(array.first()->nComponents());
  Angle a;
  a.setDegreeAzimuth(angle);
  _fixedRotation.setX(a.cos());

double ArrayCore::FKHorizontal::value	(	double	x,

Re-mplemement this function to calculate the 2D function for x and y aligned to a grid. x and y correspond to index in the grid: index=iy * nx + ix

If nothing is cached re-implementation of this function is useless.
