Expand description
The QCborArray::ConstIterator class provides an STL-style const iterator for QCborArray.
C++ class: QCborArray::ConstIterator
.
The QCborArray::ConstIterator class provides an STL-style const iterator for QCborArray.
QCborArray::ConstIterator allows you to iterate over a QCborArray. If you want to modify the QCborArray as you iterate over it, use QCborArray::Iterator instead. It is generally good practice to use QCborArray::ConstIterator, even on a non-const QCborArray, when you don't need to change the QCborArray through the iterator. Const iterators are slightly faster and improves code readability.
Iterators are initialized by using a QCborArray function like QCborArray::begin() or QCborArray::end(). Iteration is only possible after that.
Most QCborArray functions accept an integer index rather than an iterator. For that reason, iterators are rarely useful in connection with QCborArray. One place where STL-style iterators do make sense is as arguments to generic algorithms.
Multiple iterators can be used on the same array. However, be aware that any non-const function call performed on the QCborArray will render all existing iterators undefined.
