Class BridgeMethodUtils

java.lang.Object

org.graalvm.compiler.bytecode.BridgeMethodUtils

public class BridgeMethodUtils
extends Object

Utilities for working around the absence of method annotations and parameter annotations on bridge methods where the bridged methods have method annotations or parameter annotations. Not all Java compilers copy method annotations and parameter annotations to bridge methods.

Method Detail

getBridgedMethod

public static ResolvedJavaMethod getBridgedMethod(ResolvedJavaMethod bridge)

Gets the method bridged to by a bridge method. The value returned is the method called by method that has the same name as bridge.

Parameters:

bridge - a bridge method

Returns:

the method called by bridge whose name is the same as bridge.getName()

getAnnotation

public static <T extends Annotation> T getAnnotation(Class<T> annotationClass,
                                                     ResolvedJavaMethod method)

A helper for AnnotatedElement.getAnnotation(Class) that handles the absence of annotations on bridge methods where the bridged method has annotations.

getAnnotations

public static Annotation[] getAnnotations(ResolvedJavaMethod method)

A helper for AnnotatedElement.getAnnotations() that handles the absence of annotations on bridge methods where the bridged method has annotations.

getDeclaredAnnotations

public static Annotation[] getDeclaredAnnotations(ResolvedJavaMethod method)

A helper for AnnotatedElement.getDeclaredAnnotations() that handles the absence of annotations on bridge methods where the bridged method has annotations.

getParameterAnnotations

public static Annotation[][] getParameterAnnotations(ResolvedJavaMethod method)

A helper for ResolvedJavaMethod.getParameterAnnotations() that handles the absence of parameter annotations on bridge methods where the bridged method has parameter annotations.

getParameterAnnotation

public static <T extends Annotation> T getParameterAnnotation(Class<T> annotationClass,
                                                              int parameterIndex,
                                                              ResolvedJavaMethod method)

A helper for ResolvedJavaMethod.getParameterAnnotation(Class, int) that handles the absence of parameter annotations on bridge methods where the bridged method has parameter annotations.
