Member Function Documentation

virtual void BTCache::changeOutputPath ( const QString &  outputpath )

inlinevirtual

Changes output path.

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

Parameters

outputpath

New output path

Definition at line 69 of file btcache.h.

virtual void BTCache::changeTmpDir ( const QString &  ndir )

inlinevirtual

Changes the tmp dir.

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

Parameters

ndir	The new tmpdir

Definition at line 62 of file btcache.h.

virtual void BTCache::close ( )

inlinevirtual

Close the cache file(s).

Definition at line 113 of file btcache.h.

virtual void BTCache::create ( )

inlinevirtual

Create all the data files to store the data.

Definition at line 108 of file btcache.h.

void BTCache::dataArrived ( const KIO::fileoffset_t &  offset, const QByteArray &  data  )

signal

void BTCache::deleteDataFiles ( )

inlinevirtual

Delete all data files, in case of multi file torrents empty directories should also be deleted.

Definition at line 139 of file btcache.h.

virtual Uint64 BTCache::diskUsage ( )

inlinevirtual

Get the number of bytes all the files of this torrent are currently using on disk.

Definition at line 147 of file btcache.h.

virtual void BTCache::downloadStatusChanged ( TorrentFile *  , bool    )

inlinevirtual

Does nothing, can be overridden to be alerted of download status changes of a TorrentFile.

Definition at line 121 of file btcache.h.

virtual QString BTCache::getOutputPath ( ) const

inlinevirtual

Get the actual output path.

Returns

The output path
