protected final void afterDone()

Overrides com.google.common.util.concurrent.AbstractFuture.afterDone.

Doc from com.google.common.util.concurrent.AbstractFuture.afterDone.

Callback method that is called exactly once after the future is completed.

If interruptTask is also run during completion, afterDone runs after it.

The default implementation of this method in AbstractFuture does nothing. This is intended for very lightweight cleanup work, for example, timing statistics or clearing fields. If your task does anything heavier consider, just using a listener with an executor.
