Functions

currentFileName()

QString QResourceFileEngineIterator::currentFileName ( ) const

virtual

This pure virtual function returns the name of the current directory entry, excluding the path.

See also

currentFilePath()

Implements QAbstractFileEngineIterator.

Definition at line 83 of file qresource_iterator.cpp.

{
    if (index <= 0 || index > entries.size())
        return QString();
    return entries.at(index - 1);
}

hasNext()

bool QResourceFileEngineIterator::hasNext ( ) const

virtual

This pure virtual function returns true if there is at least one more entry in the current directory (i.

e., the iterator path is valid and accessible, and the iterator has not reached the end of the entry list).

See also

QDirIterator::hasNext()

Implements QAbstractFileEngineIterator.

Definition at line 67 of file qresource_iterator.cpp.

Referenced by next().

{
    if (index == -1) {
        // Lazy initialization of the iterator
        QResource resource(path());
        if (!resource.isValid())
            return false;

        // Initialize and move to the next entry.
        entries = resource.children();
        index = 0;
    }

    return index < entries.size();
}

next()

QString QResourceFileEngineIterator::next ( )

virtual

This pure virtual function advances the iterator to the next directory entry, and returns the file path to the current entry.

This function can optionally make use of nameFilters() and filters() to optimize its performance.

Reimplement this function in a subclass to advance the iterator.

QDirIterator::next()

Implements QAbstractFileEngineIterator.

{
    if (!hasNext())
        return QString();
    ++index;
    return currentFilePath();
}
