@Internal @Deprecated public class InternalDataStreamQueryOperation<E> extends Object implements org.apache.flink.table.operations.QueryOperation
DataStream.
This is only used for testing.
This operation may expose only part, or change the order of the fields available in a CompositeType of the underlying DataStream. The
getFieldIndices() describes the mapping between fields
of the TableSchema to the CompositeType.
