thenAcceptAsync (Future method)
Last update:
May 18, 2026
After this Future succeeds, runs a side-effect action on the async executor. The action receives the result and returns nothing useful to the chain.
Description
Use thenAcceptAsync for logging, assigning to outer variables, or other work that consumes the result without returning a new mapped value. The next stage still receives the same completion as thenApplyAsync would propagate; chaining continues with a Future that completes after the action runs.
Returns
A new Future.
