Detailed Description

Work-function to read a graph from the given input file.

Uses the user-provided reader to read each line and add the edges from the line to the graph.

operator()()

template<typename Graph , typename LineReader >

void stapl::parallel_reader::operator()	(	std::istream &	ifs,
		LineReader const &	line_reader,
		Graph *	g,
		size_t	blk_sz = 4096,
		bool	sharded = false
	)

Parameters

ifs	The input file-stream.
line_reader	The functor used to read-in a line of text from file and add the appropriate edges to the provided aggregator, LineReader is given a stream with the line and an Edge-Aggregator. It should read the stream and add the appropriate edges to the provided Aggregator. LineReader should return '0' for success, '1' for failure.
g	A pointer to the output graph. Vertices must have been added apriory.
blk_sz	The size of the block (in number of lines), in which the input file will be partitioned to be read.
sharded	Indicates if the graph has been sharded across multiple files.
