Package kotlin.jvm.internal

Class AdaptedFunctionReference

java.lang.Object

kotlin.jvm.internal.AdaptedFunctionReference

All Implemented Interfaces:

Serializable, kotlin.Function, kotlin.jvm.internal.FunctionBase

@SinceKotlin(version="1.4")
public class AdaptedFunctionReference
extends Object
implements kotlin.jvm.internal.FunctionBase, Serializable

Superclass for instances of adapted function references, i.e. references where expected function type differs from the target function signature:

     fun target(s: String? = ""): String = s!!
     fun use(f: () -> Unit) {}
     use(::target)  // adapted function reference (default argument conversion + coercion to Unit)
 

It doesn't inherit from FunctionReference because such references don't support reflection yet. Once this changes in the future, the JVM codegen may simply use FunctionReferenceImpl for adapted function references instead of this class.
