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

See also

getCurveCount

Exceptions

luciad::InvalidArgumentException

when requesting an invalid index.

Reimplemented in luciad::ArcBand, and luciad::PolylineRing.

getCurveCount()

virtual size_t luciad::CompositeRing::getCurveCount ( ) const

virtual

Returns the number of curves in this composite.

Returns

the number of curves in this composite.

getLength2D()

double luciad::CompositeRing::getLength2D ( ) const

overridevirtual

Returns the length of the curve.

Returns

the length of the curve.

Exceptions

luciad::InvalidArgumentException

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

Implements luciad::Curve.

Reimplemented in luciad::PolylineRing.

getReference()

std::shared_ptr< CoordinateReference > luciad::CompositeRing::getReference ( ) const

overridevirtual

Returns the coordinate reference of the geometry.

Returns

the coordinate reference of the geometry.

Implements luciad::Geometry.
