Package kotlin.jvm.internal

Class AdaptedFunctionReference

  • All Implemented Interfaces:
    java.io.Serializable, kotlin.Function, kotlin.jvm.internal.FunctionBase
    @SinceKotlin(version="1.4")
public class AdaptedFunctionReference
extends java.lang.Object
implements kotlin.jvm.internal.FunctionBase, java.io.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.
