Detailed Description

template<typename T, typename ListType = QList<T>>
class QPatternist::ListIterator< T, ListType >

Bridges values in Qt's QList container class into an QAbstractXmlForwardIterator.

Note

This class or function is reentrant.

Since

4.4

Warning

This function is not part of the public interface.

ListIterator takes a reference to a QList<T> instance and allows access to that list via its QAbstractXmlForwardIterator interface. ListIterator is parameterized with the type to iterate over, e.g., Item or Expression::Ptr.

ListIterator is used by the ExpressionSequence to create an iterator over its operands. The iterator will be passed to a MappingIterator.

inlinevirtual

Performs a copy of this QAbstractXmlForwardIterator(with copy()), and returns its items in a QList.

Warning

This function is not part of the public interface.

Thus, this function acts as a conversion function, converting the sequence to a QList.

This function may modify the iterator. It is not a getter, but potentially alters the iterator in the same way the next() function does. If this QAbstractXmlForwardIterator must not be modified, such that it can be used for evaluation with next(), use a copy().

Reimplemented from QAbstractXmlForwardIterator< T >.

related

An object generator for ListIterator.

makeListIterator() is a convenience function to avoid specifying the full template instantiation for ListIterator. Conceptually, it is identical to Qt's qMakePair().

    {
        return typename ListIterator<T>::Ptr(new ListIterator<T>(list));
