NAME
    FingerprintsFileUtil

SYNOPSIS
    use Fingerprints::FingerprintsFileUtil;

    use Fingerprints::FingerprintsFileUtil qw(:all);

DESCRIPTION
    FingerprintsFileUtil module provides the following functions:

    GetFingerprintsFileType, NewFingerprintsFileIO,
    ReadAndProcessFingerpritsData

    FingerprintsFileUtil module provides function to handle fingerprints
    data strings in FP, SD and CSV/TSV text files present in one of the
    following two types: fingerprints bit-vectors and fingerprints vector
    strings

    Example of FP file format containing fingerprints bit-vector string
    data:

FUNCTIONS
    GetFingerprintsFileType
            $FileType = GetFingerprintsFileType($FileName);

        Returns fingerprints FileType of *FileName* determined using
        extension of file name. Possible FileType values: *FP, SD, Text*.
        Supported file name extensions for various file types are: FP -
        *fpf, fp*; SD - *sdf, sd*; Text - *csv, tsv*.

    NewFingerprintsFileIO
            $FingerprintsFileIO = NewFingerprintsFileIO(%IOParameters);

        Using specified *IOParameters* property names and values hash,
        NewFingerprintsFileIO method creates a new object using appropriate
        fingerprints file IO class - FingerprintsFPFileIO,
        FingerprintsSDFileIO, or FingerprintsTextFileIO - and returns a
        reference to a newly created FingerprintsFileIO object.

        The *IOParameters* hash must contain *Name* and *Mode* as key/value
        pairs to create a new FingerprintsFileIO object.

        Based on type of file - FP, SD or Text - NewFingerprintsFileIO use
        new method from appropriate class - FingerprintsFPFileIO - along
        with *IOParameters* to create FingerprintsFileIO object.

    ReadAndProcessFingerpritsData
            ($CompoundIDsRef, $FingerprintsObjectRef) =
                            ReadAndProcessFingerpritsData($FingerprintsFileIO);

        Processes fingerprints bit-vector and vector string data in a file
        using *FingerprintsFileIO* object and returns a references to arrays
        of CompoundIDs and *FingerprintsObjects*.

        The file open and close is automatically performed during
        processing.
