General purpose call to go through the existing datasets.

If <user> is 0 or "*", act on all datasets for the given <group>. If <group> is 0 or "*", act on all datasets. If <dsName> is defined, only the information about the specified dataset is processed. Action depends on option; available options:

kExport Return a TMap object containing all the information about datasets in the form: { <group>, <map of users> } | { <map of datasets>, <dataset>} (<dataset> are TFileCollection objects) kShowDefault as kExport with in addition a default selection including the datasets from the current user, the ones from the group and the common ones

kPrint print the dataset content; no output is returned kList get a list of available dataset names kForceScan Re-open files while processing kPrint (do not use the pre-processed information) kNoHeaderPrint Labelling header is not printed kQuotaUpdate update {group, user} quotas; no output is returned

NB1: options "kPrint", "kQuoatUpdate" and "kExport" are mutually exclusive NB2: for options "kPrint" and "kQuoatUpdate" return is null.

◆ GetDataSets() [2/2]

TMap * TDataSetManagerFile::GetDataSets	(	const char *	uri,
		UInt_t	option = `TDataSetManager::kExport`
	)

virtual

Returns all datasets for the <group> and <user> specified by <uri>.

If <user> is 0, it returns all datasets for the given <group>. If <group> is 0, it returns all datasets. The returned TMap contains: <group> --> <map of users> --> <map of datasets> --> <dataset> (TFileCollection)

The unsigned int 'option' is forwarded to GetDataSet and BrowseDataSet. Available options (to be .or.ed): kShowDefault a default selection is shown that include the ones from the current user, the ones from the group and the common ones kPrint print the dataset content kQuotaUpdate update quotas kExport use export naming

NB1: options "kPrint", "kQuoatUpdate" and "kExport" are mutually exclusive NB2: for options "kPrint" and "kQuoatUpdate" return is null.

◆ NotifyUpdate()

Int_t TDataSetManagerFile::NotifyUpdate	(	const char *	group,
		const char *	user,
		const char *	dsName,
		Long_t	mtime,
		const char *	checksum = `0`
	)

virtual

Save into the <datasetdir>/kDataSet_DataSetList file the name of the updated or created or modified dataset.

For still existing datasets, fill the modification date in seconds anf the checksum. Returns 0 on success, -1 on error

Reimplemented from TDataSetManager.

Definition at line 382 of file TDataSetManagerFile.cxx.

◆ ParseInitOpts()

void TDataSetManagerFile::ParseInitOpts ( const char * ins )

virtual

Parse the input string and set the init bits accordingly Format is dir:<datasetdir> [mss:<mss-url>] [opt:<base-options>] The <datasetdir> is mandatory.

See TDataSetManager::ParseInitOpts for the available base options. The base options are already initialized by the base constructor

◆ RegisterDataSet()

Int_t TDataSetManagerFile::RegisterDataSet	(	const char *	uri,
		TFileCollection *	newDataSet,
		const char *	opts
	)

virtual

Register a dataset, perfoming quota checkings and verification, if required.

If a dataset with the same name already exists the action fails unless 'opts' contains 'O', in which case the old dataset is overwritten, or contains 'U', in which case 'newDataSet' is added to the existing dataset (duplications are ignored, if any). If 'opts' contains 'V' the dataset files are also verified (if the dataset manager is configured to allow so). By default the dataset is not verified. If 'opts' contains 'T' the in the dataset object (status bits, meta,...) is trusted, i.e. not reset (if the dataset manager is configured to allow so). Returns 0 on success, -1 on failure

◆ ScanDataSet() [2/2]

Int_t TDataSetManagerFile::ScanDataSet	(	const char *	uri,
		UInt_t	opt = `kReopen \| kDebug`
	)

virtual

Scans the dataset indicated by <uri> and returns the number of missing files.

Returns -1 if any failure occurs, >= 0 on success. For more details, see documentation of ScanDataSet(TFileCollection *dataset, const char *option)

Reimplemented from TDataSetManager.

◆ WriteDataSet()

Int_t TDataSetManagerFile::WriteDataSet	(	const char *	group,
		const char *	user,
		const char *	dsName,
		TFileCollection *	dataset,
		UInt_t	option = `0`,
		TMD5 *	checksum = `0`
	)

Writes indicated dataset.

If option has the bit kFileMustExist set, the file must still exist, otherwise the new dataset is not written (returns 3 in this case). If checksum is non-zero the files current checksum is checked against it, if it does not match the file is not written (the function returns 2 in this case, if the file has disappeared it is also not written (i.e. checksum implies the bit kFileMustExist set in option). Returns != 0 for success, 0 for error
