uk.gov.gchq.gaffer.data.element.function.ElementTupleDefinition

All Implemented Interfaces:

Serializable, Cloneable, Map<String,Object>

public class ElementTupleDefinition
extends HashMap<String,Object>

An ElementTupleDefinition is a HashMap that stores a mapping between the key names and the relevant part of an Element used for creation of Elements from data structures like MapTuples. For example, the key "id" in the MapTuple can be mapped to the vertex for Element creation.
