size (FileSizeField) -- The size of the file (in bytes)
verified (models.DateTimeField) -- The time and date that the file was verified within the NLA system
stage (models.IntegerField) --
The stage that the file is at, one of UDTAR
- U: UNVERIFIED (3)

static add(file_path, size)¶

Method to add a logical path as a TapeFile if its not already present on the NLA system.

Parameters

file_path (string) -- The (original) logical path to the file, before it was archived to tape
size (integer) -- The size of the file, in bytes

archive_volume_path()¶

Return the current volume path for a file. e.g. /datacentre/archvol/pan52/archive

static load_storage_paths()¶: Load the fileset logical paths to spotname mappings by retrieving the spotnames from a URL, finding the corresponding logical path for the spot and reformatiing them into a dictionary

match(pattern)¶

Return whether the logical path of this TapeFile matches the input pattern (a UNIX filesystem pattern).

Parameters: pattern (string) -- The UNIX filesystem pattern to match against
Returns: True | False
Return type: boolean

spotname()¶

Return portion of path that maps to spot name, and the spotname for a file. e.g. /badc/cira/data/x.dat -> /badc/cira, spot-1234-cira

This function is used to give the elements needed to construct a storage path.
