  3. type Frame = water.fvec.Frame

  4. type H2O = water.H2O

  5. trait H2OConf extends AnyRef

    Just simple configuration holder which is representing properties passed from user to H2O App.

  6. class H2OContext extends Logging with H2OConf with Serializable

    Simple H2O context motivated by SQLContext.

  7. abstract class H2OContextImplicits extends AnyRef

    Holder for implicit conversions available on H2OContext

  8. implicit class H2ODataFrameReader extends AnyRef
