Class GafferPopEdge

  • All Implemented Interfaces:
    org.apache.tinkerpop.gremlin.structure.Edge, org.apache.tinkerpop.gremlin.structure.Element

    public final class GafferPopEdge
    extends GafferPopElement
    implements org.apache.tinkerpop.gremlin.structure.Edge
    A GafferPopEdge is an GafferPopElement and Edge.

    An ID is required to be a List which contains the source, group, and destination of an edge.

        public <V> org.apache.tinkerpop.gremlin.structure.Property<V> propertyWithoutUpdate​(String key,
                                                                                            V value)
        Updates the properties attached to this Edge but without modifying the underlying graph. This method is largely a helper for generating GafferPopEdge objects from Gaffer Edge returned from the graph. In this situation we want to be able to create a representative GafferPopEdge but without modifying the one stored in the graph.
        Type Parameters:
        V - Value type
        Parameters:
        key - The key
        value - The value
        Returns:
        The property
