Value Members

  1. def apply[VD](vertices: RDD[(VertexId, VD)], edges: EdgeRDD[_], defaultVal: VD, mergeFunc: (VD, VD) ⇒ VD)(implicit arg0: ClassTag[VD]): VertexRDD[VD]

    Constructs a VertexRDD from an RDD of vertex-attribute pairs.

    Constructs a VertexRDD from an RDD of vertex-attribute pairs. Duplicate vertex entries are merged using mergeFunc. The resulting VertexRDD will be joinable with edges, and any missing vertices referred to by edges will be created with the attribute defaultVal.

    VD

    the vertex attribute type

    vertices

    the collection of vertex-attribute pairs

    edges

    the EdgeRDD that these vertices may be joined with

    defaultVal

    the vertex attribute to use when creating missing vertices

    mergeFunc

    the commutative, associative duplicate vertex attribute merge function

  2. def apply[VD](vertices: RDD[(VertexId, VD)], edges: EdgeRDD[_], defaultVal: VD)(implicit arg0: ClassTag[VD]): VertexRDD[VD]

    Constructs a VertexRDD from an RDD of vertex-attribute pairs.

    Constructs a VertexRDD from an RDD of vertex-attribute pairs. Duplicate vertex entries are removed arbitrarily. The resulting VertexRDD will be joinable with edges, and any missing vertices referred to by edges will be created with the attribute defaultVal.

    VD

    the vertex attribute type

    vertices

    the collection of vertex-attribute pairs

    edges

    the EdgeRDD that these vertices may be joined with

    defaultVal

    the vertex attribute to use when creating missing vertices

  3. def apply[VD](vertices: RDD[(VertexId, VD)])(implicit arg0: ClassTag[VD]): VertexRDD[VD]

    Constructs a standalone VertexRDD (one that is not set up for efficient joins with an EdgeRDD) from an RDD of vertex-attribute pairs.

    Constructs a standalone VertexRDD (one that is not set up for efficient joins with an EdgeRDD) from an RDD of vertex-attribute pairs. Duplicate entries are removed arbitrarily.

    VD

    the vertex attribute type

    vertices

    the collection of vertex-attribute pairs

  4. def fromEdges[VD](edges: EdgeRDD[_], numPartitions: Int, defaultVal: VD)(implicit arg0: ClassTag[VD]): VertexRDD[VD]

    Constructs a VertexRDD containing all vertices referred to in edges.

    Constructs a VertexRDD containing all vertices referred to in edges. The vertices will be created with the attribute defaultVal. The resulting VertexRDD will be joinable with edges.

    VD

    the vertex attribute type

    edges

    the EdgeRDD referring to the vertices to create

    numPartitions

    the desired number of partitions for the resulting VertexRDD

    defaultVal

    the vertex attribute to use when creating missing vertices
