DataSetRel

node into a DataSet

translateToPlan
in interface DataSetRel
tableEnv
- BatchTableEnvironment
of the translated Table.expectedType
- specifies the type the Flink operator should return. The type must
have the same arity as the result. For instance, if the
expected type is a RowTypeInfo this method will return a DataSet of
type Row. If the expected type is Tuple2, the operator will return
a Tuple2 if possible. Row otherwise.Copyright © 2014–2017 The Apache Software Foundation. All rights reserved.
