Detailed Description

Vertex are Coordinates with a unique ID and that is linked to an Edge.

Constructor & Destructor Documentation

Vertex::Vertex	(	const float	x = 0.,
		const float	y = 0.,
		Edge *	edge = NULL
	)

Creat a new Vertex.

Parameters

x	coordinate
y	coordinate
edge	reference to an Edge that have this new Vertex for origin

Returns

a new and well initialized Vertex

Vertex::Vertex	(	const Coordinates	c,
		Edge *	edge = NULL
	)

Creat a new Vertex.

Parameters

c	Coordinates that defined position of new Vertex
edge	reference to an Edge that have this new Vertex for origin

Returns

a new and well initialized Vertex

Vertex::~Vertex

Destructor Forget all VirtualVertex

Member Function Documentation

void Vertex::forget

(

VirtualVertex *

trob

)

Parameters

trob	a VirtualVertex that will be forgeted by this

Note

if this have not trob in memory, nothing is done by that function.

trob is not modified

Reimplemented in VertexGroup.

Edge * Vertex::getEdge

(

)

const

Returns

an Edge that had this Vertex for origin

VirtualVertex * Vertex::getFirstObject

(

)

const

Access to one VirtualVertex of this instance.

Returns

a VirtualVertex pointer, or NULL if no Object referenced

Reimplemented in VertexGroup.

std::list< VirtualVertex * > Vertex::getObjects

(

unsigned int

nb = 0

)

const

Access to all VirtualVertexs of this instance.

Parameters

nb	number of objects returned. If 0, default or greater than object count, all are returned.

Returns

a std::list of VirtualVertex pointers

Reimplemented in VertexGroup.

void Vertex::giveVirtualVerticesTo

(

Vertex *

v

)

Parameters

v	a Vertex that will receive all VirtualVertex of this

Reimplemented in VertexGroup.

bool Vertex::have

(

VirtualVertex *

vv

)

const

Parameters

vv	a VirtualVertex address

Returns

true iff this have vv in objects list

Reimplemented in VertexGroup.

bool Vertex::isACorner

(

)

const

Returns

true iff this is referenced by triangulation and is one of the four corner vertice

Reimplemented in VertexGroup.

bool Vertex::isNeighbourOf

(

Vertex *

v

)

const

Parameters

v	a Vertex return true iff an edge have for origin this and for destination v

Reimplemented in VertexGroup.

void Vertex::setEdge

(

Edge *

e

)

Parameters

e	the reference to an Edge, the new Edge that have this Vertex for origin

void Vertex::take	(	VirtualVertex *	trob,
		Vertex *	ancient = NULL
	)

Parameters

trob	a VirtualVertex that will be added in list of this
ancient	the Vertex that have trob, and that will forget it, or NULL (default value)

Note

trob is modified by a call to setVertex(this)

Reimplemented in VertexGroup.
