Method Detail

getMethodOrFail

public static java.lang.reflect.Method getMethodOrFail(java.lang.Class<?> clazz,
                                                       java.lang.String methodName,
                                                       java.lang.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,
                                                      java.lang.String className)

Registers a class for reflective construction via its default constructor.

registerConstructorsForReflection

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

Registers all constructors of a class for reflection.

registerClassForReflection

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

Registers an entire class for reflection use.

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

Registers a class for unsafe reflective field access.
