Method

registerClassForReflection(Feature.FeatureAccess access, String name)

public static void registerClassForReflection(Feature.FeatureAccess access, String name)

Registers an entire class for reflection use.

Parameters

Name	Description
access	org.graalvm.nativeimage.hosted.Feature.FeatureAccess
name	String
