----------------------------------

             Summary: Add factory methods to the Java TupleX types
                 Key: FLINK-2359
                 URL: https://issues.apache.org/jira/browse/FLINK-2359
             Project: Flink
          Issue Type: Improvement
          Components: Java API
    Affects Versions: 0.10
            Reporter: Gabor Gevay
            Assignee: Gabor Gevay
            Priority: Minor


The compiler doesn't infer generic type arguments from constructor arguments, which means that we have to call Tuple constructors like this:

Tuple2<Integer, String> = new Tuple2<Integer, String>(5, "foo");

I propose adding a factory method, which would provide the following alternative:

Tuple2<Integer, String> = Tuple2.create(5, "foo");

(Note that C++ and C# Tuples also have similar factory methods for the same reason.)
