getLoaderStrategy()

AbstractGraphLoaderStrategy* te::graph::GraphDataManager::getLoaderStrategy

(

)

Function used to get the current loader strategy.

Returns

A valid pointer to a loader strategy if exist and a null pointer in other case

loadGraphDataByEdgeId()

void te::graph::GraphDataManager::loadGraphDataByEdgeId	(	int	edgeId,
		te::graph::GraphCache *	gc = 0
	)

Load a set of edges elements that includes the desired element.

Parameters

edgeId	The edge identifier of the desired element.
gc	A Graph Cache used to verify if the element already in memory

loadGraphDataByVertexId()

void te::graph::GraphDataManager::loadGraphDataByVertexId	(	int	vertexId,
		te::graph::GraphCache *	gc = 0
	)

Load a set of vertex elements that includes the desired element.

Parameters

vertexId	The vertex identifier of the desired element.
gc	A Graph Cache used to verify if the element already in memory

removeEdge()

void te::graph::GraphDataManager::removeEdge

(

int

id

)

Function used to remove a edge from data source.

Parameters

id	The edge Id

removeVertex()

void te::graph::GraphDataManager::removeVertex

(

int

id

)

Function used to remove a vertex from data source.

Parameters

id	The vertex Id

saveGraphData()

void te::graph::GraphDataManager::saveGraphData

(

GraphData *

data

)

Save the graph data structure in Data Source.

Parameters

data	A graph data with a group of vertex and edge elements

Note

Only the elements with a flag new with true value will be saved and the elements with the flag dirty with true value will be updated the other elements will be ignored

setLoaderStrategy()

void te::graph::GraphDataManager::setLoaderStrategy

(

AbstractGraphLoaderStrategy *

loaderStrategy

)

Function used to set a current loader strategy.

Parameters

loaderStrategy

A pointer to loader strategy implementation
