\brief The QByteArrayList class provides a list of byte arrays.
\ingroup tools
\ingroup shared
\ingroup string-processing
\reentrant
QByteArrayList is actually just a QList<QByteArray>. It is documented as a
full class just for simplicity of documenting the member methods that exist
only in QList<QByteArray>.
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.
