Left joins this RDD with another VertexRDD with the same index. This function will fail if both VertexRDDs do not share the same index. The resulting vertex set contains an entry for each vertex in this. If other is missing any vertex in this VertexRDD, f is passed None.

Specified by:

```
Description copied from class: VertexRDD

Left joins this VertexRDD with an RDD containing vertex attribute pairs. If the other RDD is backed by a VertexRDD with the same index then the efficient leftZipJoin implementation is used. The resulting VertexRDD contains an entry for each vertex in this. If other is missing any vertex in this VertexRDD, f is passed None. If there are duplicates, the vertex is picked arbitrarily.

Specified by:

leftJoin in class VertexRDD<VD>

Parameters:

other - the other VertexRDD with which to join

f - the function mapping a vertex id and its attributes in this and the other vertex set to a new vertex attribute.

evidence$6 - (undocumented)

evidence$7 - (undocumented)

Returns:

a VertexRDD containing all the vertices in this VertexRDD with the attributes emitted by f.

innerJoin
```
public <U,VD2> VertexRDD<VD2> innerJoin(RDD<scala.Tuple2<Object,U>> other,
                                        scala.Function3<Object,VD,U,VD2> f,

```
Description copied from class: VertexRDD

Inner joins this VertexRDD with an RDD containing vertex attribute pairs. If the other RDD is backed by a VertexRDD with the same index then the efficient innerZipJoin implementation is used.

Specified by:

innerJoin in class VertexRDD<VD>

Parameters:

other - an RDD containing vertices to join. If there are multiple entries for the same vertex, one is picked arbitrarily. Use aggregateUsingIndex to merge multiple entries.

f - the join function applied to corresponding values of this and other

evidence$10 - (undocumented)

evidence$11 - (undocumented)

Returns:

a VertexRDD co-indexed with this, containing only vertices that appear in both this and other, with values supplied by f

aggregateUsingIndex
```
public <VD2> VertexRDD<VD2> aggregateUsingIndex(RDD<scala.Tuple2<Object,VD2>> messages,
                                                scala.Function2<VD2,VD2,VD2> reduceFunc,
                                                scala.reflect.ClassTag<VD2> evidence$12)
```
Description copied from class: VertexRDD

Aggregates vertices in messages that have the same ids using reduceFunc, returning a VertexRDD co-indexed with this.

Specified by:

aggregateUsingIndex in class VertexRDD<VD>

Parameters:

messages - an RDD containing messages to aggregate, where each message is a pair of its target vertex ID and the message data

reduceFunc - the associative aggregation function for merging messages to the same vertex

evidence$12 - (undocumented)

Returns:

a VertexRDD co-indexed with this, containing only vertices that received messages. For those vertices, their values are the result of applying reduceFunc to all received messages.

reverseRoutingTables
```
public VertexRDD<VD> reverseRoutingTables()
```
Description copied from class: VertexRDD

Returns a new VertexRDD reflecting a reversal of all edge directions in the corresponding EdgeRDD.

Specified by:

reverseRoutingTables in class VertexRDD<VD>

Returns:

(undocumented)

withEdges
```
public VertexRDD<VD> withEdges(EdgeRDD<?> edges)
```
Description copied from class: VertexRDD

Prepares this VertexRDD for efficient joins with the given EdgeRDD.

Specified by:

withEdges in class VertexRDD<VD>
