Hi [~raminqaf], can i work on this, could you please guide me on this?
> OBJECT_OF function's type don't get inferred correctly during comparison

> Key: FLINK-38083
> URL: https://issues.apache.org/jira/browse/FLINK-38083
> Project: Flink
> Issue Type: Sub-task
> Reporter: Ramin Gharib
> Priority: Minor
>
> Whenever we compare a structure type in the example below with one that was
> created through the `OBJECT_OF` function, the types don't match correctly.
> {code:java}
> public static class Type1 {
> public Integer a;
> public String b;
> public static class Type1Constructor extends ScalarFunction {
> public Type1 eval(Integer a, String b) {
> final Type1 t = new Type1();
> t.a = a;
> t.b = b;
> return t;
> }
> }
> // getter and setters
> }
> {code}
> For the
> {noformat}
> ROW(42, "Bob"){noformat}
> In SQL and TableAPI, the returned type of `Type1Constructor(f0, f1)` would be
> a
> {code:java}
> "STRUCTURED<'type1class', `a` INT, `b` STRING>" {code}
> where as the OBJECT_OF(Type1.class, "a", f0, "b", f1) would yeeled:
> {code:java}
> "STRUCTURED<'type2class', `a` INT NOT NULL, `b` CHAR(3) NOT NULL>" {code}
> This will cause failure in equal expressions.
