Method Concurrent.serialize()

Method serialize

Future serialize(array(Future) futures, function(mixed, __unknown__ ... :mixed) fun, mixed ... extra)

Description

Return a Future that represents the array of mapping fun sequentially over the results of the completed futures.

This function differs from traverse() in that only one call of fun will be active at a time. This is useful when each call of fun uses lots of resources, but may increase latency.

If fun() fails for one of the items, it will not be called for any others.

Note

The returned Future does NOT have any state (eg backend) propagated from the futures. This must be done by hand.
