Class FromConfig

  • All Implemented Interfaces:
    Pool, RouterConfig,
    Direct Known Subclasses:

    public class FromConfig
    extends java.lang.Object
    implements Pool
    Java API: Wraps a Props to mark the actor as externally configurable to be used with a router. If a 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).

      • resizer

        public scala.Option<Resizer> resizer()
        Description copied from interface: Pool
        Pool with dynamically resizable number of routees return the 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.
        Specified by:
        resizer in interface Pool
