virtual void te::graph::TopDownLoaderStrategy::loadDataByEdgeId	(	int	edgeId,
		te::graph::AbstractGraph *	g,
		te::graph::GraphCache *	gc = `0`
	)

pure virtual

Functio used to load a group of edges elements given a base element.

Parameters

edgeId	Attribute used to identify the base element
g	Pointer to a graph, parent of this element
gc	This is a optional attribute, if present the cache will be check if the already been loaded

Implements te::graph::AbstractGraphLoaderStrategy.

◆ loadDataByVertexId()

virtual void te::graph::TopDownLoaderStrategy::loadDataByVertexId	(	int	vertexId,
		te::graph::AbstractGraph *	g,

	)

pure virtual

Functio used to load a group of vertex elements given a base element.

Parameters

vertexId	Attribute used to identify the base element
g	Pointer to a graph, parent of this element
gc	This is a optional attribute, if present the cache will be check if the already been loaded

Implements te::graph::AbstractGraphLoaderStrategy.

◆ loadEdge()

Edge * te::graph::AbstractGraphLoaderStrategy::loadEdge ( int id )

protectedinherited

Function used to load one edge given a ID.

Parameters

id	The edge identifier

Note: This function is used in case the graph was saved using the edge list

Returns: A valid edge pointer if the element was found and a null pointer in other case

◆ loadEdgeAttrs()

Edge * te::graph::AbstractGraphLoaderStrategy::loadEdgeAttrs ( int id )

protectedinherited

Function used to load one edge given a ID.

Parameters

id	The edge identifier

Note: This function is used in case the graph was saved using the vertex list

Parameters

id	The vertex identifier

Note: This function is used in case the graph was saved using the vertex list

Returns: A valid vertex pointer if the element was found and a null pointer in other case

◆ loadVertexAttrs()

Vertex * te::graph::AbstractGraphLoaderStrategy::loadVertexAttrs ( int id )

protectedinherited

Function used to load one vertex given a ID.

Parameters

id	The vertex identifier

Note: This function is used in case the graph was saved using the edge list

Returns: A valid vertex pointer if the element was found and a null pointer in other case
