    \brief The QByteArrayList class provides a list of byte arrays.

    \ingroup tools
    \ingroup shared
    \ingroup string-processing

    \reentrant

    QByteArrayList inherits from QList<QByteArray>. Like QList, QByteArrayList is
    \l{implicitly shared}. It provides fast index-based access as well as fast
    insertions and removals. Passing string lists as value parameters is both
    fast and safe.

    All of QList's functionality also applies to QByteArrayList. For example, you
    can use isEmpty() to test whether the list is empty, and you can call
    functions like append(), prepend(), insert(), replace(), removeAll(),
    removeAt(), removeFirst(), removeLast(), and removeOne() to modify a
    QByteArrayList. In addition, QByteArrayList provides several join()
    methods for concatenating the list into a single QByteArray.

    The purpose of QByteArrayList is quite different from that of QStringList.
    Whereas QStringList has many methods for manipulation of elements within
    the list, QByteArrayList does not.
    Normally, QStringList should be used whenever working with a list of printable
    strings. QByteArrayList should be used to handle and efficiently join large blobs
    of binary data, as when sequentially receiving serialized data through a
    QIODevice.

    \l{implicitly shared}, making the process of returning a
    QByteArrayList from a function very fast. If a shared instance is
    modified, it will be copied (copy-on-write), and that takes
    \l{linear time}.
