protected JoinOperator.DefaultJoin<I1,I2> |
JoinOperator.JoinOperatorSets.JoinOperatorSetsPredicate.createJoinOperator(Keys<I2> keys2) |
JoinOperator.DefaultJoin<I1,I2> |
JoinOperator.JoinOperatorSets.JoinOperatorSetsPredicate.equalTo(int... fields)
Continues a Join transformation and defines the
Tuple fields of the second join
DataSet that should be used as join keys.Note: Fields can only be selected as join keys on Tuple DataSets. The resulting JoinOperator.DefaultJoin wraps each pair of joining elements into a Tuple2, with
the element of the first input being the first field of the tuple and the element of the
second input being the second field of the tuple. |
<K> JoinOperator.DefaultJoin<I1,I2> |
JoinOperator.JoinOperatorSets.JoinOperatorSetsPredicate.equalTo(KeySelector<I2,K> keySelector)
Continues a Join transformation and defines a
KeySelector function for the second join DataSet.
The KeySelector function is called for each element of the second DataSet and extracts a single
key value on which the DataSet is joined. |
JoinOperator.DefaultJoin<I1,I2> |
JoinOperator.JoinOperatorSets.JoinOperatorSetsPredicate.equalTo(String... fields)
Continues a Join transformation and defines the fields of the second join
DataSet that should be used as join keys.The resulting JoinOperator.DefaultJoin wraps each pair of joining elements into a Tuple2, with
the element of the first input being the first field of the tuple and the element of the
second input being the second field of the tuple. |
