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 long long XrdFileCache::IOEntireFile::FSize ( ) [virtual]

Implements XrdOucCacheIO.

virtual int XrdFileCache::IOEntireFile::Fstat ( struct stat & sbuff ) [virtual]

Perform an fstat() operation (defaults to passthrough).

Parameters:

sbuff

reference to the stat buffer to be filled in. Only fields st_size, st_blocks, st_mtime (st_atime and st_ctime may be set to st_mtime), st_ino, and st_mode need to be set. All other fields are preset and should not be changed.

Returns:: <0 - fstat failed, value is -errno. =0 - fstat succeeded, sbuff holds stat information. >0 - fstat could not be done, forward operation to next level.

Reimplemented from XrdOucCacheIO2.

bool XrdFileCache::IOEntireFile::HasFile ( ) const [inline]

Check if File was opened successfully.
