<R> JoinOperatorSetsBase<T,R> |
DataSet.fullOuterJoin(DataSet<R> other)
Initiates a Full Outer Join transformation.
An Outer Join transformation joins two elements of two DataSets on key equality and provides multiple ways to combine
joining elements into one DataSet.Elements of both DataSets that do not have a matching element on the opposing side are joined with null and emitted to the
resulting DataSet. |
<R> JoinOperatorSetsBase<T,R> |
DataSet.fullOuterJoin(DataSet<R> other,
JoinOperatorBase.JoinHint strategy)
Initiates a Full Outer Join transformation.
An Outer Join transformation joins two elements of two DataSets on key equality and provides multiple ways to combine
joining elements into one DataSet.Elements of both DataSets that do not have a matching element on the opposing side are joined with null and emitted to the
resulting DataSet. |
<R> JoinOperatorSetsBase<T,R> |
DataSet.leftOuterJoin(DataSet<R> other)
Initiates a Left Outer Join transformation.
An Outer Join transformation joins two elements of two DataSets on key equality and provides multiple ways to combine
joining elements into one DataSet.Elements of the left DataSet (i.e. |
