    statsReceiver

    maintains stats and gauges used in resolution

    stabilizerWindow

    the window over which we stabilize updates from zk as per the semantics of the Stabilizer.

    unhealthyWindow

    how long must the zk client be unhealthy before reporting trouble

    inetResolver

    used to perform address resolution

    timer

    timer to use for stabilization and zk sessions

    Bind a string into a variable address using the zk2 scheme.

    Bind a string into a variable address using the zk2 scheme.

    NOTE: This specific API doesn't take "zk2!" as a protocol prefix, but when used with just Resolver, "zk2!" is expected as a prefix. Clients should be using the Resolver API rather than this direct interface.

    Argument strings must adhere to either of the following formats:

    <hosts>:2181!<path> <hosts>:2181!<path>!<endpoint>

    where

    - <hosts>: The hostname(s) of service discovery ZooKeeper cluster - <path>: A ServerSet path (e.g. /twitter/service/userservice/prod/server) - <endpoint>: An endpoint name (optional)
