Member Function Documentation
| virtual XrdOucCacheIO* XrdFileCache::IOEntireFile::Detach | ( | ) | [virtual] |
Detach itself from Cache. Note: this will delete the object.
- Returns:
- original source XrdPosixFile
Reimplemented from XrdOucCacheIO.
| virtual bool XrdFileCache::IOEntireFile::ioActive | ( | ) | [virtual] |
Virtual method of XrdOucCacheIO. Called to check if destruction needs to be done in a separate task.
Reimplemented from XrdOucCacheIO.
| virtual int XrdFileCache::IOEntireFile::Read | ( | char * | Buffer, | |
| long long | Offset, | |||
| int | Length | |||
| ) | [virtual] |
Pass Read request to the corresponding Prefetch object.
- Parameters:
-
Buffer Offset Length
- Returns:
- number of bytes read
Implements XrdOucCacheIO.
| virtual int XrdFileCache::IOEntireFile::ReadV | ( | const XrdOucIOVec * | readV, | |
| int | n | |||
| ) | [virtual] |
Pass ReadV request to the corresponding Prefetch object.
- Parameters:
-
readV n number of XrdOucIOVecs
- Returns:
- total bytes read
Reimplemented from XrdOucCacheIO.
| virtual void XrdFileCache::IOEntireFile::StartPrefetch | ( | ) | [protected, virtual] |
Run prefetch outside constructor.
Reimplemented from XrdFileCache::IO.
