Kotlin DSL Building Overriding invoke method to build DSL
Example
If you have:
class MyExample(val i: Int) {
operator fun <R> invoke(block: MyExample.() -> R) = block()
fun Int.bigger() = this > i
}
you can write the following DSL-like code in your production code:
fun main2(args: Array<String>) {
val ex = MyExample(233)
ex {
// bigger is defined in the context of `ex`
// you can only call this method inside this context
if (777.bigger()) kotlin.io.println("why")
}
}
