Class CSVEventDrivenImporter

  • All Implemented Interfaces:

    public class CSVEventDrivenImporter
    extends BaseEventDrivenImporter<java.lang.String,​Triple<java.lang.String,​java.lang.String,​java.lang.Double>>
    implements EventDrivenImporter<java.lang.String,​Triple<java.lang.String,​java.lang.String,​java.lang.Double>>
    Imports a graph from a CSV Format or any other Delimiter-separated value format.

    The importer supports various different formats which can be adjusted using the setFormat method. The supported formats are the same CSV formats used by Gephi. For some of the formats, the behavior of the importer can be adjusted using the setParameter method. See CSVFormat for a description of the formats.

    The importer respects rfc4180. The caller can also adjust the separator to something like semicolon or pipe instead of comma. In such a case, all fields are unescaped using the new separator. See Delimiter-separated values for more information.

    This importer does not distinguish between CSVFormat.EDGE_LIST and CSVFormat.ADJACENCY_LIST. In both cases it assumes the format is CSVFormat.ADJACENCY_LIST.
