Detailed Description

Abstract class handling node or edge mapping between a CSV column and a graph property.

Be sure there is a property with the given name in the graph or an error will occur. Automatically handle CSV file parsing just implements the buildIndexForRow function to fill the rowToGraphId map with the right graph element.

virtual unsigned int tlp::AbstractCSVToGraphDataMapping::buildIndexForRow	(	unsigned int	row,
		const std::string &	indexKey,
		tlp::Graph *	graph,
		tlp::PropertyInterface *	keyProperty
	)			[protected, pure virtual]

Create a new element if no elements for the given row was found.

Returns:

Return the graph element id or UINT_MAX if no new element is created.

Implemented in tlp::CSVToGraphNodeIdMapping, and tlp::CSVToGraphEdgeIdMapping.
