Member Function Documentation

virtual XrdOucCacheIO2* XrdPosixCacheBCIO::Base

(

)

[inline, virtual]

Reimplemented from XrdOucCacheIO.

References cacheIO2.

virtual XrdOucCacheIO2* XrdPosixCacheBCIO::Detach

(

)

[inline, virtual]

Reimplemented from XrdOucCacheIO.

References cacheIO1, cacheIO2, and XrdOucCacheIO::Detach().

virtual long long XrdPosixCacheBCIO::FSize

(

)

[inline, virtual]

Implements XrdOucCacheIO.

References cacheIO1, and XrdOucCacheIO::FSize().

virtual int XrdPosixCacheBCIO::Fstat

(

struct stat &

sbuff

)

[inline, 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.

References cacheIO2, and XrdOucCacheIO2::Fstat().

virtual bool XrdPosixCacheBCIO::ioActive

(

)

[inline, virtual]

Reimplemented from XrdOucCacheIO.

References cacheIO1, and XrdOucCacheIO::ioActive().

virtual const char* XrdPosixCacheBCIO::Location

(

)

[inline, virtual]

Get the file's location (i.e. endpoint hostname and port)

Returns:

A pointer to the file's location. It remains valid until the file is closed. A null string means the file is not open or is unknown.

Reimplemented from XrdOucCacheIO2.

References cacheIO2, and XrdOucCacheIO2::Location().

virtual const char* XrdPosixCacheBCIO::Path

(

)

[inline, virtual]

Implements XrdOucCacheIO.
