@Internal
 @Deprecated
public class InternalDataStreamQueryOperation<E>
extends Object
implements QueryOperation

Describes a relational operation that reads from a 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.
