Creates a storage from the existing file or directory together with an appropriate MetaInfo file as can be announced on the given announce String location. |
|
Storage(I2PSnarkUtil util,
MetaInfo metainfo,
StorageListener listener)
Creates a new storage based on the supplied MetaInfo. |
Method Summary | |
---|---|
void |
check(String rootDir)
Creates (and/or checks) all files from the metainfo file list. |
void |
check(String rootDir,
long savedTime,
BitField savedBitField)
use a saved bitfield and timestamp from a config file |
void |
cleanRAFs()
|
void |
close()
Closes the Storage and makes sure that all RandomAccessFiles are closed. |
boolean |
complete()
Whether or not this storage contains all pieces if the MetaInfo. |
void |
create()
|
String |
getBaseName()
The base file or directory name of the data, as specified in the .torrent file, but filtered to remove illegal characters. |
BitField |
