		UInt_t	option = `0`,
		TMD5 **	checksum = `0`
	)

Returns the dataset <dsName> of user <user> in group <group> .

If checksum is non-zero, it will contain the pointer to a TMD5 sum object with the checksum of the file, has to be deleted by the user. If option has the bi kReadShort set, the shortobject is read, that does not contain the list of files. This is much faster.

protected

Do the real inititialization.

Definition at line 93 of file TDataSetManagerFile.cxx.

◆ InitLocalCache()

void TDataSetManagerFile::InitLocalCache ( )

private

Init the local cache if required.

Definition at line 234 of file TDataSetManagerFile.cxx.

◆ 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

Reimplemented from TDataSetManager.

Definition at line 317 of file TDataSetManagerFile.cxx.

◆ 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

Reimplemented from TDataSetManager.

◆ RemoveDataSet() [1/2]

Bool_t TDataSetManagerFile::RemoveDataSet	(	const char *	group,
		const char *	user,
		const char *	dsName
	)

protected

Removes the indicated dataset.

Definition at line 1544 of file TDataSetManagerFile.cxx.

◆ RemoveDataSet() [2/2]

Bool_t TDataSetManagerFile::RemoveDataSet ( const char * uri )

virtual

Removes the indicated dataset.

Reimplemented from TDataSetManager.

Definition at line 1930 of file TDataSetManagerFile.cxx.

◆ ScanDataSet() [1/2]

Int_t TDataSetManagerFile::ScanDataSet	(	const char *	group,
		const char *	user,
		const char *	dsName,
		UInt_t	option = `kReopen \| kDebug`
	)

protected

See documentation of ScanDataSet(TFileCollection *dataset, UInt_t option)

Definition at line 1783 of file TDataSetManagerFile.cxx.

◆ 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.

Definition at line 1730 of file TDataSetManagerFile.cxx.

◆ ShowCache()

Int_t TDataSetManagerFile::ShowCache ( const char * uri = 0 )

virtual

Show cached information matching uri.

Reimplemented from TDataSetManager.

Definition at line 1319 of file TDataSetManagerFile.cxx.

◆ UpdateUsedSpace()

void TDataSetManagerFile::UpdateUsedSpace ( )

protectedvirtual

updates the used space maps

Reimplemented from TDataSetManager.

Definition at line 1959 of file TDataSetManagerFile.cxx.

◆ 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
