Member Function Documentation

◆ CheckFileStatus()

Bool_t KVDMSDataRepository::CheckFileStatus	(	const KVDataSet *	ds,
		const Char_t *	datatype,
		const Char_t *	runfile
	)

virtual

Checks if the run file of given type is physically present in dataset subdirectory, i.e. (schematically), if

/root_of_data_repository/[datasetdir]/[datatypedir]/[runfile]

exists. If it does, the returned value is kTRUE (=1).

Reimplemented from KVDataRepository.

Definition at line 167 of file KVDMSDataRepository.cpp.

◆ CheckSubdirExists()

Bool_t KVDMSDataRepository::CheckSubdirExists	(	const Char_t *	dir,
		const Char_t *	subdir = `0`
	)

virtual

Returns kTRUE if the following path is valid /root_of_data_repository/dir/[subdir]

Reimplemented from KVDataRepository.

Definition at line 81 of file KVDMSDataRepository.cpp.

◆ Chmod()

int KVDMSDataRepository::Chmod	(	const char *	file,
		UInt_t	mode
	)

privatevirtual

Overrides KVDataRepository method.

Reimplemented from KVDataRepository.

Definition at line 248 of file KVDMSDataRepository.cpp.

◆ CopyFileFromRepository()

void KVDMSDataRepository::CopyFileFromRepository	(	const KVDataSet *	ds,
		const Char_t *	datatype,
		const Char_t *	filename,
		const Char_t *	destination
	)

virtual

Copy file [datasetdir]/[datatypedir]/[filename] from the repository to [destination] We check if the file to copy exists.

Reimplemented from KVDataRepository.

Definition at line 112 of file KVDMSDataRepository.cpp.

◆ CopyFileToRepository()

int KVDMSDataRepository::CopyFileToRepository	(	const Char_t *	source,
		const KVDataSet *	ds,
		const Char_t *	datatype,
		const Char_t *	filename
	)

virtual

Copy file [source] to [datasetdir]/[datatypedir]/[filename] in the repository Returns status of file transfer command

Reimplemented from KVDataRepository.

Definition at line 138 of file KVDMSDataRepository.cpp.

◆ DeleteFile()

void KVDMSDataRepository::DeleteFile	(	const KVDataSet *	ds,
		const Char_t *	datatype,
		const Char_t *	filename,
		Bool_t	confirm = `kTRUE`
	)

virtual

Delete repository file [datasetdir]/[datatypedir]/[filename]

By default (confirm=kTRUE) we ask for confirmation before deleting. Set confirm=kFALSE to delete without confirmation (DANGER!!!)

Reimplemented from KVDataRepository.

Definition at line 211 of file KVDMSDataRepository.cpp.

◆ GetDirectoryListing()

KVUniqueNameList * KVDMSDataRepository::GetDirectoryListing	(	const KVDataSet *	ds,
		const Char_t *	datatype = `""`,
		const Char_t *	subdir = `""`
	)

virtual

Use the DMS catalogue in order to examine the directory

/root_of_data_repository/[datasetdir]/[datatype]/[subdir] /root_of_data_repository/[datasetdir]/[datatype] (if subdir="", default value) /root_of_data_repository/[datasetdir] (if datatype="", default value)

and fill a TList with one KVDMSFile_t object for each entry in the directory, User must delete the TList after use (list will delete its members)

Reimplemented from KVDataRepository.

Definition at line 46 of file KVDMSDataRepository.cpp.

◆ GetFileInfo()

Bool_t KVDMSDataRepository::GetFileInfo	(	const KVDataSet *	ds,
		const Char_t *	datatype,
		const Char_t *	runfile,
		FileStat_t &	fs
	)

virtual

Checks if the run file of given type is physically present in dataset subdirectory, i.e. (schematically), if

/root_of_data_repository/[datasetdir]/[datatypedir]/[runfile]

exists. If it does, the returned value is kTRUE (=1), in which case the FileStat_t object contains information about the file: WARNING: only fs.fSize and fs.fMtime are used in addition, the modification time corresponds to the last time that the DMS declaration of the file was changed, not the last physical modification of the file, i.e. it will be the date at which the file was imported into the DMS catalogue, the file may be much older.

Reimplemented from KVDataRepository.

Definition at line 271 of file KVDMSDataRepository.cpp.

◆ GetFullPathToOpenFile()

const Char_t * KVDMSDataRepository::GetFullPathToOpenFile	(	const KVDataSet *	dataset,
		const Char_t *	datatype,
		const Char_t *	runfile
	)

virtual

Redefinition of KVDataRepository::GetFullPathToOpenFile

If ReadProtocol != "root" then we use the DMS to download copies of data repository files to the user's temporary directory for analysis - see OpenDataSetRunFile. In this case, the full path to open the given file is that of the temporary directory copy get read protocol for dataset and datatype

Reimplemented from KVDataRepository.

Definition at line 315 of file KVDMSDataRepository.cpp.

◆ MakeSubdirectory()

void KVDMSDataRepository::MakeSubdirectory	(	const KVDataSet *	ds,
		const Char_t *	datatype = `""`
	)

virtual

Overrides KVDataRepository method.

Reimplemented from KVDataRepository.

Definition at line 191 of file KVDMSDataRepository.cpp.

◆ OpenDataSetRunFile()

TObject * KVDMSDataRepository::OpenDataSetRunFile	(	const KVDataSet *	ds,
		const Char_t *	type,
		Int_t	run,
		Option_t *	opt = `""`
	)

virtual

Overrides KVDataRepository method

If ReadProtocol == "root" we use KVDataRepository method to open file via xrootd server

If ReadProtocol != "root" (default if user does not specify [name].DataRepository.ReadProtocol:root):

1) we look for a copy of the file in the user's temporary directory (gSystem->TempDirectory()); 2) if no copy exists, we download the file to the user's temporary directory 3) we open the file in the user's temporary directory get read protocol for dataset and datatype

Reimplemented from KVDataRepository.
