due to this design decision, then this must be clearly stated in the README to prevent developers from running into such an issue. If rialization is unable to serialize Map, etc. I understand that there was an explicit (and useful) design decision to not use reflection.I thought it'd be trivial to serialize a Map because gson and jackson do it out of the box but apparently not. I only realized this after already spending ~2 days migrating nearly a thousand lines of serialization code, and now I've rolled back to using jackson instead. I'm using the graphql-java library which returns a Map (i.e., Map), and I'm unable to figure out how to properly convert this into a JsonObject or JsonElement which means it's impossible for me to use rialization. Guess you could use reflections to iterate over all fields but wouldn't that be overkill? *obviously it will only work with primitives and maps/arrays of primitives - if you attempt to serialize/deserialize complex objects it won't work. Override fun serialize(encoder: Encoder, value: Any) Override val descriptor: SerialDescriptor = buildClassSerialDescriptor("Any") The following code will print all the integers between 0 and 100 that are divisible by 3 and 5.If anyone is looking for generic Map serialization based on some preliminary testing this seems to work for me class Generic( To do something useful with the iterator, we can use some of the other methods from the standard library e.g. The following code will create an infinite iterator over the integers 0, 1, 2, 3.: var i = 0 For infinite iterators, just never return null. In Part 1, I'll be going over the default Kotlin namespace.īoth the API docs and the source code for the stdlib are available on github.įirst up, the iterate method creates an iterator from a stateful function that returns either a value if it has more data or a null if not. In this series, I thought I'd look at some of the highlights of the Kotlin stdlib. Exploring the API docs and source code for a language's standard library is usually illuminating and Kotlin is no different.
