A filter is an atomic adapter which can selectively strip granules from the data flow.
Inside the filter, there is some programming logic which checks every input granule, and returns a pass/fail answer.
Any granules that fail the test are dropped from the data flow.
An example: a filter could be set up to drop any word granules that contain a word that starts with a lower case letter.
