computePoint()

luciad::Coordinate luciad::CircleByCenterPoint::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.

getBounds()

Bounds luciad::CircleByCenterPoint::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.

getCenter()

luciad::Coordinate luciad::CircleByCenterPoint::getCenter

(

)

const

Returns the center of the circle.

Returns

the center of the circle.

getHash()

size_t luciad::CircleByCenterPoint::getHash ( ) const

overrideprotectedvirtual

Returns the hash value for this geometry.

Returns

the hash value for this geometry.

Implements luciad::Geometry.

getLength2D()

double luciad::CircleByCenterPoint::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.

getRadius()

double luciad::CircleByCenterPoint::getRadius

(

)

const

Returns the radius of the circle.

If the coordinate reference is a geodetic reference, this is expressed in meters. Otherwise the unit of the reference is used.

Returns

the radius of the circle.

getReference()

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

overridevirtual

Returns the coordinate reference of the geometry.

Returns

the coordinate reference of the geometry.

Implements luciad::Geometry.
