Combine

case class Combine(in: CompNode, f: (Any, Any) ⇒ Any, wfk: WireReaderWriter, wfv: WireReaderWriter, nodeSinks: Seq[Sink] = ..., bridgeStoreId: String = ...) extends ProcessNodeImpl with Product with Serializable

The Combine node type specifies the building of a CompNode as a result of applying an associative function to the values of an existing key-values CompNode
