Reads in a multi-line list of edges from multiple files in a directory, which nodes have ids of type T. Does not check for duplicate edges or nodes.
You can optionally specify which files in a directory to read. For example, you may have files starting with "part-" that you'd like to read. Only these will be read in if you specify that as the file prefix.
You should also specify
nodeNumberer,idReaderfor reading node ids.For a default version for
Intgraphs see ListOfEdgesGraphReader.forIntIds builder method.In each file, a directed edges is defined by a pair of T: from and to. For example, we use
Stringids withseparator, when reading file:In this file, node
ahas two outgoing edges (tobande), nodebhas an outgoing edge to nodedand nodedhas an outgoing edge to nodec.Note that, it is recommended to use AdjacencyListGraphReader, because of its efficiency.
