Constructor & Destructor Documentation

BALL::Triangle::Triangle

(

)

Default constructor. This method creates a new Triangle object.

BALL::Triangle::Triangle	(	TrianglePoint *	v1,
		TrianglePoint *	v2,
		TrianglePoint *	v3
	)

Detailed constructor. Creates a new Triangle object. Its vertices are initialized with the passed TrianglePoint instances.

BALL::Triangle::Triangle	(	TriangleEdge *	e1,
		TriangleEdge *	e2,
		TriangleEdge *	e3,
		bool	flip_normal = false
	)

Detailed constructor. Creates a new Triangle object. Its edges are initialized with the passed TriangleEdge instances. Its vertices are taken from the edges. This requires the edges to be properly oriented in a counter clockwise manner.

BALL::Triangle::Triangle	(	const Triangle &	triangle,
		bool	deep = false
	)

Copy constructor. Create a new Triangle object from another.

Parameters:

	triangle	the Triangle object to be copied
	deep	if deep = false, all pointers are set to NULL (default). Otherwise the new Triangle object is linked to the neighbours of the old Triangle object.

virtual BALL::Triangle::~Triangle

(

)

[virtual]

Destructor. Destructs the Triangle object.

Member Function Documentation

TrianglePoint* BALL::Triangle::getPoint

(

Position

i

)

const throw (Exception::IndexOverflow)

Return one of the three points of the Triangle.

Parameters:

i

the relative index of the point which should be given back. If i is greater three, an exception is thrown.

Returns:

TrianglePoint* a pointer to the asked point

virtual bool BALL::Triangle::operator!=

(

const Triangle &

)

const [virtual]

Inequality operator.

Returns:

false

Reimplemented from BALL::GraphTriangle< TrianglePoint, TriangleEdge, Triangle >.

virtual bool BALL::Triangle::operator*=

(

const Triangle &

)

const [virtual]

Similarity operator.

Returns:

true

Reimplemented from BALL::GraphTriangle< TrianglePoint, TriangleEdge, Triangle >.

Triangle& BALL::Triangle::operator=

(

const Triangle &

triangle

)

Assign from another Triangle. The Triangle object is linked to the neighbours of the Triangle object to assign from

Parameters:

triangle

the Triangle object to assign from

virtual bool BALL::Triangle::operator==

(

const Triangle &

)

const [virtual]

Equality operator.

Returns:

true

Reimplemented from BALL::GraphTriangle< TrianglePoint, TriangleEdge, Triangle >.

void BALL::Triangle::remove

(

TriangleEdge *

edge

)

Remove an edge from the Triangle. The edge is set to NULL.

Parameters:

edge

the edge to delete

void BALL::Triangle::set	(	const Triangle &	triangle,
		bool	deep = false
	)

Assign from another Triangle.

Parameters:

	triangle	the Triangle object to assign from
	deep	if deep = false, all pointers are set to NULL (default). Otherwise the Triangle object is linked to the neighbours of the Triangle object to assign from

void BALL::Triangle::setPoint	(	Position	i,
		TrianglePoint *	point
	)			throw (Exception::IndexOverflow)

Set one of the three points of the Triangle.

Parameters:

	i	the relative index of the point which should be set. If i is greater three, an exception is thrown.
	point	a pointer to the new point
