Member Function Documentation

◆ Detach()

bool XrdRmcData::Detach ( XrdOucCacheIOCD & iocd )

virtual

Detach this CacheIO object from the cache.

Note: This method must be called instead of using the delete operator since CacheIO objects may have multiple outstanding references and actual deletion may need to be defered.

Parameters

iocd	reference to the detach complete callback object.

Returns: true Deletion can occur immediately. There is no outstanding I/O.; false Deletion must be deferred until it is safe to so from the cache perspective. At which point, the cache will call the DetachDone() method in the passed callback object. No locks may be held with respect to the CacheIO object when this is done to avoid deadlocks.

Implements XrdOucCacheIO.

◆ FSize()

long long XrdRmcData::FSize ( )

inlinevirtual

Obtain size of the file.

Returns: Size of the file in bytes.

Implements XrdOucCacheIO.

References XrdOucCacheIO::FSize(), and ioObj.

◆ Path()

const char* XrdRmcData::Path ( )

inlinevirtual

Get the path associated with this object.

Returns: Pointer to the path.

Implements XrdOucCacheIO.

References ioObj, and XrdOucCacheIO::Path().

◆ Preread() [1/3]

void XrdRmcData::Preread ( )

◆ Preread() [2/3]

void XrdRmcData::Preread ( aprParms & Parms )

virtual

Reimplemented from XrdOucCacheIO.

◆ Preread() [3/3]

void XrdRmcData::Preread	(	long long	Offs,
		int	rLen,
		int	Opts = `0`
	)

virtual

Reimplemented from XrdOucCacheIO.

◆ QueuePR()

void XrdRmcData::QueuePR	(	long long	SegOffs,
		int	rLen,
		int	prHow,
		int	isAuto = `0`
	)

private

◆ Read() [1/2]

int XrdRmcData::Read	(	char *	buff,
		long long	offs,
		int	rlen
	)

virtual

Perform an synchronous read.

Parameters

buff	pointer to the buffer to receive the results. The buffer must remain valid until the callback is invoked.
offs	the offset into the file.
rlen	the number of bytes to read.

Returns: < 0 - Read failed, value is -errno. >=0 - Read succeeded, value is number of bytes read.

Implements XrdOucCacheIO.

◆ Read() [2/2]

int XrdRmcData::Read	(	XrdOucCacheStats &	Now,
		char *	Buffer,
		long long	Offs,
		int	Length
	)

private

◆ setAPR()

static int XrdRmcData::setAPR	(	aprParms &	Dest,
		aprParms &	Src,
		int	pSize
	)

static

◆ Sync()

int XrdRmcData::Sync ( )

inlinevirtual

Perform an synchronous sync() operation.

Returns: <0 - Sync failed, value is -errno. =0 - Sync succeeded.

Implements XrdOucCacheIO.

◆ Trunc()

int XrdRmcData::Trunc ( long long offs )

virtual

Perform an synchronous trunc() operation.

Parameters

offs	the size the file is have.

Returns: <0 - Trunc failed, value is -errno. =0 - Trunc succeeded.

Implements XrdOucCacheIO.

◆ Write()

int XrdRmcData::Write	(	char *	buff,
		long long	offs,
		int	wlen
	)

virtual

Perform an synchronous write.

Parameters

buff	pointer to the buffer holding the contents. The buffer must remain valid until the callback is invoked.
offs	the offset into the file.
wlen	the number of bytes to write

Returns: < 0 - Write failed, value is -errno. >=0 - Write succeeded, value is number of bytes written.

Implements XrdOucCacheIO.
