Construct a graph from a collection of vertices and edges with attributes.
Construct a graph from a collection of vertices and edges with attributes. Duplicate vertices are picked arbitrarily and vertices found in the edge collection but not in the input vertices are assigned the default attribute.
the vertex attribute type
the edge attribute type
the "set" of vertices and their attributes
the collection of edges in the graph
the default vertex attribute to use for vertices that are mentioned in edges but not in vertices
Construct a graph from a collection of edges encoded as vertex id pairs.
Construct a graph from a collection of edges encoded as vertex id pairs.
a collection of edges in (src, dst) form
if multiple identical edges are found they are combined and the edge
attribute is set to the sum. Otherwise duplicate edges are treated as separate. To enable
uniqueEdges
, a PartitionStrategy must be provided.
a graph with edge attributes containing either the count of duplicate edges or 1
(if uniqueEdges
is None
) and vertex attributes containing the total degree of each vertex.
Construct a graph from a collection of edges.
Construct a graph from a collection of edges.
the RDD containing the set of edges in the graph
the default vertex attribute to use for each vertex
a graph with edge attributes described by edges
and vertices
given by all vertices in edges
with value defaultValue
Implicitly extracts the GraphOps member from a graph.
The Graph object contains a collection of routines used to construct graphs from RDDs.
