Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static Method`	`getMethodOrFail(Class<?> clazz, String methodName, Class<?>... params)`	Returns the method of a class or fails if it is not present.

Method Detail

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(org.graalvm.nativeimage.hosted.Feature.FeatureAccess access,
                                              String name)

Registers an entire class for reflection use.

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.
