kotlin

问题 We have a package that we are looking to convert to kotlin from python in order to then be able to migrate systems using that package. Within the package there are a set of classes that are all variants, or 'flavours' of a common base class. Most of the code is in the base class which has a significant number of optional parameters. So consider: open class BaseTree(val height:Int=10,val roots:Boolean=true, //...... lots more!! class FruitTree(val fruitSize, height:Int=10, roots:Boolean=true,

问题 So I'm trying to read data from a .json file in my Android project: val file = context.assets.open("myfile.json").bufferedReader().readText() This works fine and successfully prints out my .json file as one String . However I want to know what exactly is bufferedReader() and why .readText() can't be called directly on the opened .json file. PS: readText() returns a String . However: val json2: JSONObject = JSONObject("mystring") returns: Caused by: org.json.JSONException: Value mystring of

The updated item is synchronized across all devices. */ fun putItem(){ .... } /** * "same KDOC here with above" */ fun putItem(putRequest: PutDataRequest){ .... } Is there any possibility to copy/link the docs of the second method to be the same with the first one?
