Detailed Description
template<class Stream>
class NSDiskIO::AbstractDiskIO< Stream >
abstract base for DiskIO-things
opens files for reading/writing and sets the QTextstream _stream accordingly
- Todo:
- enforce every Reader and Writer to give its prefered ending of files and a description for the selection in FileDialog
Constructor & Destructor Documentation
| NSDiskIO::AbstractDiskIO< Stream >::AbstractDiskIO | ( | QIODevice::OpenMode | openmode | ) | [inline, protected] |
normal constructor
- Parameters:
-
openmode the QIODevice::OpenMode for this file
| virtual NSDiskIO::AbstractDiskIO< Stream >::~AbstractDiskIO | ( | ) | [inline, protected, virtual] |
normal destructor
calls setFile( "" ) to close the open file
Member Function Documentation
| void NSDiskIO::AbstractDiskIO< Stream >::setFile | ( | QString | filename | ) | [inline, protected] |
open a file
When called with an argument the old opened file is closed and the new one is opened if it exists. When the argument is just empty ( "" or QString::Null ) the current file is closed.
If opening of the file fails for some reason, it closes the file and resets the state.
- Parameters:
-
filename The path and name of the file to open.
