When this Future and another Future both complete normally, runs a parameterless action on the completing thread.
Description
runAfterBoth is an instance method on a CFML Future. When this stage and other both complete successfully, your action runs on the completing thread. The action receives no arguments. Use it for cleanup or notifications that do not need the result values. A new Future is returned for chaining.
This is the synchronous counterpart to runAfterBothAsync.
Returns
A new Future.
