Extension Properties
extensionReceiverParameter
Returns a parameter representing the extension receiver instance needed to call this callable,
or
null
if this callable is not an extension.

javaSetter
Returns a Java

reflect
This is an experimental API. Given a class for a compiled Kotlin lambda or a function expression, returns a KFunction instance providing introspection capabilities for that lambda or function expression and its parameters. Not all features are currently supported, in particular KCallable.call and KCallable.callBy will fail at the moment.
setValue
An extension operator that allows delegating a mutable member or extension property of type V to a property reference to a member or extension mutable property of the same type V .
