Idiomatic way of logging in Kotlin

Question

Kotlin doesn\'t have the same notion of static fields as used in Java. In Java, the generally accepted way of doing logging is:

public class Foo {
    privat         


        

Answer 1

Would something like this work for you?

class LoggerDelegate {

    private var logger: Logger? = null

    operator fun getValue(thisRef: Any?, property: KProperty<*>): Logger {
        if (logger == null) logger = Logger.getLogger(thisRef!!.javaClass.name)
        return logger!!
    }

}

fun logger() = LoggerDelegate()

class Foo { // (by the way, everything in Kotlin is public by default)
    companion object { val logger by logger() }
}
