Member Function Documentation

◆ advance()

bool QFSFileEngineIterator::advance ( )

overridevirtual

This pure virtual function advances the iterator to the next directory entry; if the operation was successful this method returns true, otherwise it returs false.

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

Reimplement this function in a subclass to advance the iterator.

Implements QAbstractFileEngineIterator.

Here is the call graph for this function:

◆ currentFileInfo()

QFileInfo QFSFileEngineIterator::currentFileInfo ( ) const

overridevirtual

The virtual function returns a QFileInfo for the current directory entry.

This function is provided for convenience. It can also be slightly faster than creating a QFileInfo object yourself, as the object returned by this function might contain cached information that QFileInfo otherwise would have to access through the file engine.
