abstract class RegionJoin[T, U, RT, RU] extends Serializable
A trait describing a join in the genomic coordinate space between two RDDs where the values are keyed by a ReferenceRegion.
- T
The type of the left RDD.
- U
The type of the right RDD.
- RT
The type of data yielded by the left RDD at the output of the join. This may not match T if the join is an outer join, etc.
- RU
The type of data yielded by the right RDD at the output of the join.

def
partitionAndJoin(baseRDD: RDD[(ReferenceRegion, T)], joinedRDD: RDD[(ReferenceRegion, U)]): RDD[(RT, RU)]
Performs a region join between two RDDs.
Performs a region join between two RDDs.
- baseRDD
The 'left' side of the join
- joinedRDD
The 'right' side of the join
- returns
An RDD of pairs (x, y), where x is from baseRDD, y is from joinedRDD, and the region corresponding to x overlaps the region corresponding to y.
