"... | Adds a type information hint about the return type of this operator. This method
can be used in cases where Flink cannot determine automatically what the produced
type of a function is. That can be the case if the function uses generic type variables
in the return type that cannot be inferred from the input type.
<p>Classes can be used as type hints for non-generic types (classes without generic parameters),
but not for generic types like for example Tuples. For those generic types, please
use the {@link #returns(TypeHint)} method.
<p>Use this method the following way:
<pre>{@code
DataSet<String[]> result =
data1.join(data2).where("id").equalTo("fieldX")
.with(new JoinFunctionWithNonInferrableReturnType())
.returns(String[].class);
}</pre>

of the elements in the collection.
<p>The framework will try and determine the exact type from the collection elements.
In case of generic elements, it may be necessary to manually supply the type information
via {@link #fromCollection(Collection, TypeInformation)}.
<p>Note that this operation will result in a non-parallel data source, i.e. a data source with
a parallelism of one.
@param data The collection of elements to create the data set from.
@return A DataSet representing the given collection.
