Performs a mapping of incoming attributes to out-coming attributes using map functions. Odysseus also provides a wide range of mapping functions.

Hint: StateMap can use history information. To access the last n.th version of an attribute use "__last_n." Mind the two "_" at the beginning!

Parameter

Example

output = STATEMAP({
              expressions = ['auction_id * 5','sqrt(auction_id)', '__last_5.auction_id]
             }, input)
