IgniteReducer<E1,R>, Serializable

public interface R1<E1,R>
extends IgniteReducer<E1,R>

Defines alias for IgniteReducer by extending it. Since Java doesn't provide type aliases (like Scala, for example) we resort to these types of measures. This is intended to provide for more concise code in cases when readability won't be sacrificed. For more information see IgniteReducer.
