Detailed Description

The QByteArrayList class provides a list of byte arrays.

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.

Member Function Documentation

QByteArray QByteArrayList::join() const

Joins all the byte arrays into a single byte array.

QByteArray QByteArrayList::join(const QByteArray &separator) const

Joins all the byte arrays into a single byte array with each element separated by the given separator.

QByteArray QByteArrayList::join(char separator) const

Joins all the byte arrays into a single byte array with each element separated by the given separator.
