Member Function Documentation

te::gm::Envelope* te::graph::BoxLoaderStrategy::calculateBox	(	te::gm::Point *	p,
		std::string	tableName
	)

protected

Generate a box with p as center. The new box will have n% of the total graph height and n% of total graph width.

Parameters

p	Terralib object that defines a geometric point.

inherited

It returns a pointer to a class that describes the graph metadata.

Returns: A valid pointer if exists and null pointer in other case

		te::graph::AbstractGraph *	g,
		te::graph::GraphCache *	gc = `0`
	)

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.

virtual void te::graph::BoxLoaderStrategy::loadDataByVertexId	(	int	vertexId,
		te::graph::AbstractGraph *	g,
		te::graph::GraphCache *	gc = `0`
	)

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.

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

protectedinherited

Function used to load one edge given a ID.

Parameters

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

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

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

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 vertex list

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

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
