    Constructor & Destructor Documentation

    Storage ( const QString &, QObject * )

    Storage(const QString &aStorageName,
    QObject *aParent = 0
    )[protected, explicit]

    ~Storage ( )

    ~Storage()[virtual]

    Member Function Documentation

    add ( const QFile & )

    voidadd(const QFile &aFile)[pure virtual]

    Adds a file to storage. Calculates checksum for the file based on the file name and size. Basic support based on MD5 hash.

    Parameters
    aFilethe file to be added to storage, can be in either opened or closed state

    add ( const QString &, const QBuffer & )

    voidadd(const QString &aFilePath,
    const QBuffer &aData
    )[pure virtual]

    Adds an in memory file to storage. Calculates checksum for the file based on the file name and size. Basic support based on MD5 hash.

    Parameters
    aFilePaththe the file path including filename that is to be added to the storage

    count ( )

    qint32 count()const [pure virtual]

    Returns the number of files stored in the the storage.

    createInstance ( const QString &, WAC::Storage::visibility, WAC::Storage::protection, QObject * )

    Storage *createInstance(const QString &aStorageName,
    WAC::Storage::visibility = vis_shared,
    WAC::Storage::protection = prot_signed,
    QObject *aParent = 0
    )[static]

    Factory method for creating new instance of WAC::Storage class.

    getFile ( const QString & )

    QIODevice *getFile(const QString &aPathFile)[pure virtual]

    Returns a file stored in the storage. Caller becomes the owner of the QIODevice. Hence, the caller must delete the QIODevice instance.

    Return Value
    a QIODevice instance when file exists in storage, null is returned otherwise. The returned QIODevice is not opened

    getFileList ( )

    QStringList getFileList()const [pure virtual]

    Returns a list of files stored in the storage

    Return Value
    a list of file name stored in the storage.

    remove ( const QFile & )

    voidremove(const QFile &aFile)[pure virtual]

    Removes a file from storage

    Parameters
    aFileto be removed from storage, can be in either opened or closed state

    storageName ( )

    QString storageName()const [virtual]

    Returns the storage name

    verify ( const QFile & )

    boolverify(const QFile &aFile)const [pure virtual]

    Verifies that the checksum of a file matches to the stored file. Checksum is calculated from the file name, size, and last modification date of the file. Basic support based on MD5 hash.

    Parameters
    aFileto be verified, can be in either opened or closed state
