Function Documentation

ListFromFile()

python.LumiQuery.ListFromFile	(		filename = "FewEventsLumi.pool.root",
			label = "LumiBlockCollection_p1_LumiBlocks",
			metadatatree = "MetaData" )

 Returns a list of RunLumiBlock ranges (stored as python tuples of type PyRunLumiP1) from the named file.

The file should have metadata stored internally as a ROOT tree
(named 'Stream' by default). It can be a POOL file or other generic
ntuple file.

Note: This function does not access the MetaDataStore.  Please use
a LumiBlock AlgTool for that.
