java.lang.Object

uk.gov.gchq.gaffer.spark.operation.handler.graphframe.GetGraphFrameOfElementsHandler

All Implemented Interfaces:

OperationHandler<GetGraphFrameOfElements>, OutputOperationHandler<GetGraphFrameOfElements,org.graphframes.GraphFrame>

public class GetGraphFrameOfElementsHandler
extends Object
implements OutputOperationHandler<GetGraphFrameOfElements,org.graphframes.GraphFrame>

A GetGraphFrameOfElementsHandler handles GetGraphFrameOfElements operations.

The implementation delegates to GetDataFrameOfElements operation. Then the resulting Dataset of elements are split into two Datasets based on the groups provided in the View.
