void bt::MultiFileCache::changeOutputPath ( const QString & outputpath ) [virtual]

Changes output path.

All data files should already been moved. This just modifies the datadir variable.

Parameters:

outputpath

New output path

Implements bt::Cache.

Definition at line 205 of file multifilecache.cpp.

void bt::MultiFileCache::changeTmpDir ( const QString & ndir ) [virtual]

Changes the tmp dir.

All data files should already been moved. This just modifies the tmpdir variable.

Parameters:

ndir

The new tmpdir

Reimplemented from bt::Cache.
