Detailed Description

VertexGroup are Vertex, according to Composite pattern. Vertices of a VertexGroup moves together. IMPLEMENTATION INCOMPLETE

Constructor & Destructor Documentation

VertexGroup::VertexGroup

(

)

Creat a new VertexGroup.

Returns

a new and well initialized VertexGroup

VertexGroup::~VertexGroup

(

)

Destructor Forget all VirtualVertex

Member Function Documentation

void VertexGroup::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 from Vertex.

VirtualVertex * VertexGroup::getFirstObject

(

)

const

Access to one VirtualVertex of this instance.

Returns

a VirtualVertex pointer, or NULL if no Object referenced

Reimplemented from Vertex.

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

(

unsigned int

nb = 0

)

const

Access to all VirtualVertexG 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 from Vertex.

void VertexGroup::giveVirtualVerticesTo

(

Vertex *

v

)

Parameters

v	a VertexGroup that will receive all VirtualVertex of this

Reimplemented from Vertex.

bool VertexGroup::have

(

VirtualVertex *

vv

)

const

Parameters

vv	a VirtualVertex address

Returns

true iff this have vv in objects list

Reimplemented from Vertex.

bool VertexGroup::isACorner

(

)

const

Returns

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

Reimplemented from Vertex.

bool VertexGroup::isNeighbourOf

(

Vertex *

v

)

const

Parameters

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

Reimplemented from Vertex.

void VertexGroup::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 setVertexGroup(this)

Reimplemented from Vertex.
