Hi guys, Want to bring to the table this issue to see what other members of the community think and then we can codify it in the Spark coding style guide. The topic is about declaring return types explicitly in public APIs.
In general I think we should favor explicit type declaration in public APIs. However, I do think there are 3 cases we can avoid the public API definition because in these 3 cases the types are self-evident & repetitive. Case 1. toString Case 2. A method returning a string or a val defining a string def name = "abcd" // this is so obvious that it is a string val name = "edfg" // this too Case 3. The method or variable is invoking the constructor of a class and return that immediately. For example: val a = new SparkContext(...) implicit def rddToAsyncRDDActions[T: ClassTag](rdd: RDD[T]) = new AsyncRDDActions(rdd) Thoughts?
