◆ computePoint()

Coordinate luciad::Line::computePoint ( double  parameter) const
overridevirtual

Computes a point of the curve, defined by the given parameter.

  1. At parameter 0, the point is the start point of the curve.
  2. At parameter 1, the point is the end point of the curve.
Parameters
parameterthe parameter value, within [0,1], to compute the point location for.
Returns
the computed point location.
Exceptions
luciad::InvalidArgumentExceptionif parameter is not within [0,1], or if the point could not be computed. For example, when the curve is defined by invalid points.

Implements luciad::Curve.

◆ getBounds()

Bounds luciad::Line::getBounds ( ) const
overridevirtual

Returns the bounds for the geometry object.

Returns
the bounds for the geometry object.
Exceptions
luciad::InvalidArgumentExceptionif the bounds could not be computed. For example, when the geometry is defined by invalid points.

Implements luciad::Geometry.

◆ getEndPoint()

Coordinate luciad::Line::getEndPoint ( ) const

Returns the end point of the line segment.

Implements luciad::Curve.

◆ getReference()

std::shared_ptr< luciad::CoordinateReference > luciad::Line::getReference ( ) const
overridevirtual

Returns the coordinate reference of the geometry.

Returns
the coordinate reference of the geometry.
