public class EdgeRDDImpl<ED,VD> extends EdgeRDD<ED>
| Modifier and Type | Method and Description |
|---|---|
EdgeRDDImpl<ED,VD> |
cache()
Persists the edge partitions using
targetStorageLevel, which defaults to MEMORY_ONLY. |
void |
checkpoint()
Mark this RDD for checkpointing.
|
Edge<ED>[] |
collect()
Return an array that contains all of the elements in this RDD.
|
long |
count()
The number of edges in the RDD.
|

filter(scala.Function1<EdgeTriplet<VD,ED>,Object> epred,
scala.Function2<Object,VD,Object> vpred) |
scala.Option<String> |
getCheckpointFile()
Gets the name of the directory to which this RDD was checkpointed.
|
StorageLevel |
getStorageLevel()
Get the RDD's current storage level, or StorageLevel.NONE if none is set.

innerJoin(EdgeRDD<ED2> other,
scala.Function4<Object,Object,ED,ED2,ED3> f,
scala.reflect.ClassTag<ED2> evidence$4,
scala.reflect.ClassTag<ED3> evidence$5)
Inner joins this EdgeRDD with another EdgeRDD, assuming both are partitioned using the same
PartitionStrategy. |
boolean |
isCheckpointed()
Return whether this RDD is checkpointed and materialized, either reliably or locally.
|
<ED2,VD2> EdgeRDDImpl<ED2,VD2> |

<ED2> EdgeRDDImpl<ED2,VD> |
mapValues(scala.Function1<Edge<ED>,ED2> f,
scala.reflect.ClassTag<ED2> evidence$3)
Map the values in an edge partitioning preserving the structure but changing the values.
|
scala.Option<Partitioner> |
partitioner()
If
partitionsRDD already has a partitioner, use it. |
RDD<scala.Tuple2<Object,org.apache.spark.graphx.impl.EdgePartition<ED,VD>>> |
partitionsRDD() |
EdgeRDDImpl<ED,VD> |
persist(StorageLevel newLevel)
Persists the edge partitions at the specified storage level, ignoring any existing target
storage level.
|
EdgeRDDImpl<ED,VD> |
reverse()
Reverse all the edges in this RDD.
|
EdgeRDDImpl<ED,VD> |
setName(String _name)
Assign a name to this RDD
|
StorageLevel |

EdgeRDDImpl<ED,VD> |
unpersist(boolean blocking)
Mark the RDD as non-persistent, and remove all blocks for it from memory and disk.

RDDpublic scala.Option<Partitioner> partitioner()
partitionsRDD already has a partitioner, use it. Otherwise assume that the
PartitionIDs in partitionsRDD correspond to the actual partitions and create a new
partitioner that allows co-partitioning with partitionsRDD.partitioner in class RDD<Edge<ED>>public Edge<ED>[] collect()

executed on this RDD. It is strongly recommended that this RDD is persisted in
