Type	Description
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

Parameters

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

registerForReflectiveInstantiation(Feature.FeatureAccess access, String className)

public static void registerForReflectiveInstantiation(Feature.FeatureAccess access, String className)

Registers a class for reflective construction via its default constructor.

Parameters

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

registerForUnsafeFieldAccess(Feature.FeatureAccess access, String className, String[] fields)
