Method Details

getMethodOrFail

public static Method getMethodOrFail(Class<?> clazz,
 String methodName,
 Class<?>... params)

Returns the method of a class or fails if it is not present.

registerForReflectiveInstantiation

public static void registerForReflectiveInstantiation(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String className)

Registers a class for reflective construction via its default constructor.

registerConstructorsForReflection

public static void registerConstructorsForReflection(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String name)

Registers all constructors of a class for reflection.

registerClassForReflection

public static void registerClassForReflection(Class<?> clazz)

Registers an entire class for reflection use.

registerClassForReflection

public static void registerClassForReflection(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String name)

Registers an entire class for reflection use.

registerClassForJni

public static void registerClassForJni(Class<?> clazz)

Registers an entire class for JNI use.

registerClassForJni

public static void registerClassForJni(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String name)

Registers an entire class for JNI use.

registerClassHierarchyForJni

public static void registerClassHierarchyForJni(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String className)

Registers the transitive class hierarchy of the provided className for JNI use.

The transitive class hierarchy contains the class itself and its transitive set of *non-private* nested subclasses.

registerClassHierarchyForReflection

public static void registerClassHierarchyForReflection(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String className)

Registers the transitive class hierarchy of the provided className for reflection.

The transitive class hierarchy contains the class itself and its transitive set of *non-private* nested subclasses.

registerForUnsafeFieldAccess

public static void registerForUnsafeFieldAccess(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
 String className,
 String... fields)

Registers a class for unsafe reflective field access.
