Class MutablePair<T1,T2>

Object
org.apache.spark.util.MutablePair<T1,T2>
All Implemented Interfaces:
Serializable, scala.Equals, scala.Product, scala.Product2<T1,T2>, scala.Serializable
public class MutablePair<T1,T2> extends Object implements scala.Product2<T1,T2>, scala.Product, scala.Serializable
:: DeveloperApi :: A tuple of 2 elements. This can be used as an alternative to Scala's Tuple2 when we want to minimize object allocation.
