operator()()

template<typename Aggr , typename Graph >

size_t stapl::read_dimacs_line::operator()	(	std::stringstream &	ss,
		Aggr &	aggr,
		Graph *	g
	)		const

Parameters

ss	The stringstream representing a line from the input file.
aggr	The edge-aggregator to output the read edges to.
g	A pointer to the output graph. The edges may be added to the graph, or additional operations performed (i.e., setting properties for vertices and edges, etc.)

Returns

'0' for success, '1' for failure.
