Class QueryLineageResponse

    • Method Detail

      • hasVertices

        public final boolean hasVertices()
        For responses, this returns true if the service returned a value for the Vertices property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • vertices

        public final List<Vertex> vertices()

        A list of vertices connected to the start entity(ies) in the lineage graph.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasVertices() method.

        Returns:
        A list of vertices connected to the start entity(ies) in the lineage graph.
      • hasEdges

        public final boolean hasEdges()
        For responses, this returns true if the service returned a value for the Edges property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • edges

        public final List<Edge> edges()

        A list of edges that connect vertices in the response.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEdges() method.

        Returns:
        A list of edges that connect vertices in the response.
      • nextToken

        public final String nextToken()

        Limits the number of vertices in the response. Use the NextToken in a response to to retrieve the next page of results.

        Returns:
        Limits the number of vertices in the response. Use the NextToken in a response to to retrieve the next page of results.
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
