All Implemented Interfaces:

NetworkStructureChangeSensitiveNode, Node, Receiver, Supplier, Tunnel

public class DiscriminatorDispatcherNode
extends SingleInputNode
implements NetworkStructureChangeSensitiveNode

Node that sends tuples off to different buckets (attached as children of type DiscriminatorBucketNode), based on the value of a given column.

Tuple contents and bucket keys have already been wrapped using IQueryRuntimeContext.wrapElement(Object)

Since:

1.5
