Member Function Documentation

computePoint()

Coordinate luciad::CompositeRing::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

parameter

the parameter value, within [0,1], to compute the point location for.

Returns

the computed point location.

Exceptions

luciad::InvalidArgumentException

if 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.

Reimplemented in luciad::PolylineRing.

getBounds()

Bounds luciad::CompositeRing::getBounds ( ) const

overridevirtual

Returns the bounds for the geometry object.

Returns

the bounds for the geometry object.

Exceptions

luciad::InvalidArgumentException

if the bounds could not be computed. For example, when the geometry is defined by invalid points.

Implements luciad::Geometry.

Reimplemented in luciad::PolylineRing.

getCurveAt()

virtual std::shared_ptr< Curve > luciad::CompositeRing::getCurveAt ( size_t index ) const

virtual

Returns the curve for the requested index.

Parameters

index

the curve index

Returns

the curve at index

getLength2D()

double luciad::CompositeRing::getLength2D ( ) const

overridevirtual

Returns the length of the curve.
