Return a python parsable string

Reimplemented from python.trfArgClasses.argument.

    def __repr__(self):
        return '[' + ','.join([ repr(s) for s in self._value ]) + ']'
 
 

__str__()

_exists()

def python.trfArgClasses.argFile._exists (   self,   files  )

privateinherited

Try to determine if a file actually exists...

For a posix file, just call stat; for anything else call TFile.Open A small optimisation is to retieve the file_size metadatum at the same time.

Parameters

Definition at line 1176 of file trfArgClasses.py.

    def _exists(self, files):
        msg.debug('Testing existance for {0}'.format(files))

_generateGUID()

def python.trfArgClasses.argFile._generateGUID (   self,   files  )

privateinherited

Generate a GUID on demand - no intrinsic for this file type

Use uuid.uuid4() call to generate a GUID

Note

This generation method will be superceeded in any file type which actually has an intrinsic GUID (e.g. BS or POOL files)

Definition at line 1165 of file trfArgClasses.py.

_getDatasetFromFilename()

def python.trfArgClasses.argFile._getDatasetFromFilename (   self,   reset = False  )

privateinherited

Look for dataset name in dataset::filename Tier0 convention.

At the moment all files must be in the same dataset if it's specified. (To change this dataset will need to become a per-file metadatum.)

Note

dsn::lfn notation must be used for all input values and all dsn values must be the same

Parameters

_setMetadata()

def python.trfArgClasses.argFile._setMetadata (   self,   files = None,   metadataKeys = {}  )

privateinherited

Set metadata values into the cache.

Manually sets the metadata cache values to the values given in the metadata key dictionary here. This is useful for setting values to make checks on file metadata handling.

Note

To really suppress any external function calls that gather metadata be careful to also set the _exists metadatum to True.

Warning

No checks are done on the values or keys given here, so you'd better know what you are doing.

Parameters

files	Files to set metadata for (None means "all")
metadataKeys	Dictionary with metadata keys and values

Note

Variable listing set of file metadata which corresponds to this class, Key is the metadata variable name, the value is the function to call to populate/refresh this metadata value. Function must take a single parameter, which is the list of files to get metadata for. It must return a metadata dictionary: {file1 : {key1: value1, key2: value2}, file2: ...} Keys which start with _ are for transform internal use and should not appear in jobReports

Note

We have a default of None here, but all derived classes should definitely have their own value setter and translate this value to something sensible for their underlying value type. N.B. As most argument classes use this default constructor it must call the @value .setter function!
