…bogus implementation of Comparable (any such generic interface would do, as long as it forces a method with generic type to be implemented), to ensure that a Type argument is indeed given.ĬompareTo(): The only reason we define this method (and require implementation of Comparable) is to prevent constructing a reference without type information. replicationSettings.put(class, strategy) String strategyOptionsSplit. JSON automated mapping case class Resident(name: String, age: Int, role: OptionString) import. In the next step of the tour, we’ll see how they are useful in pattern matching. Case classes are good for modeling immutable data. The one of the topmost benefit of Case Class is that Scala Compiler affix a method with the name of the class having identical number of parameters as defined in the class definition, because of that you can create objects of the Case Class even in the absence of the keyword new.
#SCALA ADD JACKSON ANNOTATIONS TO CASE CLASS CODE#
The javadoc states that this is because doing so forces a compile-time check to ensure you have provided a type when instantiating a new TypeReference object: Best Java code snippets using .ObjectMapper. Case Classes Language Case classes are like regular classes with a few key differences which we will go over. Protected TypeReference () įinal note: The TypeReference class implements Comparable. I think all annotations are actually merged), but adding JacksonAnnotation on all Scala annotation definitions would make sense if that has not yet been done. Theres a nice add-on module for Jackson to support Scala data types.
