Question: What is the task of the method whose tokenized name is "online median filter test median window filling"?
Evidence: tokenized name refers to NameTokenized; task of the method refers to the second part of name deliminated by "."; for example, the task of 'LinqToDelicious.HttpWebRequestFactory.Create' is 'HttpWebRequestFactory'

SQL:
SELECT SUBSTR(SUBSTR(Name, INSTR(Name, '.') + 1), 1, INSTR(SUBSTR(Name, INSTR(Name, '.') + 1), '.') - 1) task FROM Method WHERE NameTokenized = 'online median filter test median window filling'
