Detailed Description

Class XrdoucName2Name must be used for creating a name translation plug-in. This plug-in is specified by the 'oss.namelib' directive and when present makes the default oss plug-in load the plug-in shared library, locate the XrdOucgetName2Name function within and use it to obtain an instance of the XrdOucName2Name object to perform name translation prior to all subsequent storage system calls. The companion object, XrdOucName2NameVec, should also be defined in the same shared library (see the class definition below).

Member Function Documentation

virtual int XrdOucName2Name::lfn2pfn	(	const char *	lfn,
		char *	buff,
		int	blen
	)			[pure virtual]

Map a logical file name to a physical file name.

Parameters:

	lfn	-> Logical file name.
	buff	-> Buffer where the physical file name of an existing file is to be placed. It must end with a null byte.
	blen	The length of the buffer.

Returns:

Success: Zero. Failure: An errno number describing the failure; typically EINVAL - The supplied lfn is invalid. ENAMETOOLONG - The buffer is too small for the pfn.

virtual int XrdOucName2Name::lfn2rfn	(	const char *	lfn,
		char *	buff,
		int	blen
	)			[pure virtual]

Map a logical file name to the name the file would have in a remote storage system (e.g. Mass Storage System at a remote location).

Parameters:

	lfn	-> Logical file name.
	buff	-> Buffer where the remote file name is to be placed. It need not actually exist in that location but could be created there with that name. It must end with a null byte.
	blen	The length of the buffer.

Returns:

Success: Zero. Failure: An errno number describing the failure; typically EINVAL - The supplied lfn is invalid. ENAMETOOLONG - The buffer is too small for the pfn.

virtual int XrdOucName2Name::pfn2lfn	(	const char *	pfn,
		char *	buff,
		int	blen
	)			[pure virtual]

Map a physical file name to it's logical file name.

Parameters:

	pfn	-> Physical file name. This is always a valid name of either an existing file or a file that could been created.
	buff	-> Buffer where the logical file name is to be placed. It need not actually exist but could be created with that name. It must end with a null byte.
	blen	The length of the buffer.

Returns:

Success: Zero. Failure: An errno number describing the failure; typically EINVAL - The supplied lfn is invalid. ENAMETOOLONG - The buffer is too small for the pfn.
