Class Concurrent.AggregatedPromise (< ValueType >)

Description

Promise to provide an aggregated Future value.

Objects of this class are typically kept internal to the code that provides the Future value. The only thing that is directly returned to the user is the return value from future().

Note

It is currently possible to use this class as a normal Promise (ie without aggregation), but those functions may get removed in a future version of Pike. Functions to avoid include success() and try_success(). If you do not need aggregation use Promise.
