Detailed Description

From the point of view of graph theory, vertices are treated as featureless and indivisible objects, although they may have additional structure depending on the application from which the graph arises;for instance, a semantic network is a graph in which the vertices represent concepts or classes of objects.

Note: The neighbour informartion has to be defined in a appropriated graph implementation.

Constructor & Destructor Documentation

te::graph::Vertex::Vertex	(	int	id,
		bool	isNew = `true`
	)

Constructor.

Parameters

id	The vertex identifier
isNew	Flag used to indicate that the element is new

te::graph::Vertex::Vertex ( te::graph::Vertex * rhs )

Copy constructor.

te::graph::Vertex::~Vertex ( )

Default destructor.

Member Function Documentation

void te::graph::Vertex::addAttribute	(	int	idx,
		te::dt::AbstractData *	ad
	)

Add a new attribute to this element.

Parameters

idx	Index of the new attribute (must be a valid position)
ad	AbstractData (can be any type of data)

std::vector<te::dt::AbstractData*>& te::graph::Vertex::getAttributes ( )

It returns the vector of attributes associated with this element.

Returns: A vector of AbstractData (can be any type of data)

int te::graph::Vertex::getId ( )

It returns the vertex id.

Returns: Integer with the vertex identifier

std::set<int>& te::graph::Vertex::getNeighborhood ( )

Returns the Neighborhood vector.

Note: This information only will be defined in the apropriated graph type

Returns: std::vector<int> reference

std::set<int>& te::graph::Vertex::getPredecessors ( )

Returns the Predecessors vector.

Note: This information only will be defined in the apropriated graph type

Returns: std::vector<int> reference

std::set<int>& te::graph::Vertex::getSuccessors ( )

Returns the Successors vector.

Note: This information only will be defined in the apropriated graph type

Returns: std::vector<int> reference

bool te::graph::Vertex::isDirty ( )

Used to verify the vertex state.

Returns: Boolean value used to indicate the vertex state

bool te::graph::Vertex::isNew ( )

Flag used to indicate that this element was a new one.

Returns: Boolean value used to indicate the vertex state

void te::graph::Vertex::removeAttribute ( int idx )

Remove a attribute associated with this element.

Parameters

idx	Index of the attribute (must be a valid position)

void te::graph::Vertex::setAttributeVecSize ( int size )

This function is used to set the number of attributes associated with the vertex elements.

Parameters

size	Integer value to define the attribute size

Note: Its important to use this method after a new property was associated to a edge Function defined in AbstractGraph addEdgeProperty.

void te::graph::Vertex::setDirty ( bool flag )

Flag used to indicate that this element was changed.

Parameters

flag	Boolean value used to indicate the vertex state
