Member Function Documentation

bool te::graph::QueryGraphBuilder::build	(	te::graph::AbstractGraph *	g,
		te::da::Expression *	eEdge,
		te::da::Expression *	eVertex,
		const std::string &	dsInfo,
		const std::string &	graphType,
		const std::map< std::string, std::string > &	gInfo
	)

Function used to generated the vertex id based on raster coordenate.

Parameters

g	Inpput graph
e	Expression tha defines a query
dsInfo	The necessary information to access the data source
graphType	Attribute used to define the output graph type
gInfo	Container with graph generation parameters

Returns

True if the graph was correctly generated and false in other case.
