class FromConfig extends Pool
Java API: Wraps a akka.actor.Props to mark the actor as externally configurable to be used with a router. If a akka.actor.Props is not wrapped with FromConfig then the actor will ignore the router part of the deployment section in the configuration.
This can be used when the dispatcher to be used for the head Router needs to be configured (defaults to default-dispatcher).

Pool with dynamically resizable number of routees return the akka.routing.Resizer to use. The resizer is invoked once when the router is created, before any messages can be sent to it. Resize is also triggered when messages are sent to the routees, and the resizer is invoked asynchronously, i.e. not necessarily before the message has been sent.
