Class CSVImporter<V,​E>

  • Type Parameters:
    V - the graph vertex type
    E - the graph edge type
    All Implemented Interfaces:
    GraphImporter<V,​E>
    @Deprecated
public class CSVImporter<V,​E>
extends Object
implements GraphImporter<V,​E>
    Deprecated.
    Use CSVImporter instead
    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.
