Class KotlinContextReceiverUsageMarker

java.lang.Object

proguard.optimize.kotlin.KotlinContextReceiverUsageMarker

All Implemented Interfaces:

proguard.classfile.kotlin.visitor.KotlinConstructorVisitor, proguard.classfile.kotlin.visitor.KotlinFunctionVisitor, proguard.classfile.kotlin.visitor.KotlinMetadataVisitor, proguard.classfile.kotlin.visitor.KotlinPropertyVisitor

public class KotlinContextReceiverUsageMarker
extends java.lang.Object
implements proguard.classfile.kotlin.visitor.KotlinMetadataVisitor, proguard.classfile.kotlin.visitor.KotlinFunctionVisitor, proguard.classfile.kotlin.visitor.KotlinConstructorVisitor, proguard.classfile.kotlin.visitor.KotlinPropertyVisitor

This Kotlin metadata visitor marks the parameters of methods used, using the ParameterUsageMarker, if those parameters correspond to Kotlin context receivers.

This is done to ensure that the list of context receivers does not get out of sync, as otherwise unused context receiver parameters may be removed.

On the Java method level, each context receiver is passed as a leading parameter to a function's JVM method, a property getter/setter method, or a constructor.

context(Foo, Bar) fun foo(string:String) { } // -> public static void foo(LFoo;LBar;Ljava/lang/String;)V

TODO(T18173): Implement proper shrinking of context receivers when the underlying parameter is not used i.e. consistently remove context receivers when the underlying parameter is removed in e.g. MethodDescriptorShrinker
