## Class Counter

- java.lang.Object
- - io.vertx.reactivex.core.shareddata.Counter

-     public class Counter
      extends Object

  An asynchronous counter that can be used to across the cluster to maintain a consistent count.

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.
