Annotation Type Advice.Origin

@Documented
 @Retention(value=RUNTIME)
 @Target(value=PARAMETER)
public static @interface Advice.Origin

Indicates that the annotated parameter should be mapped to a string representation of the instrumented method, a constant representing the Class declaring the adviced method or a Method, Constructor or java.lang.reflect.Executable representing this method. It can also load the instrumented method's java.lang.invoke.MethodType, java.lang.invoke.MethodHandle or java.lang.invoke.MethodHandles$Lookup.

Note: A constant representing a Method or Constructor is not cached but is recreated for every read.

Important: Don't confuse this annotation with Origin annotation. This annotation should be used only in combination with Advice ASM visitor. For method delegation (MethodDelegation.to(...)) use alternative annotation from net.bytebuddy.implementation.bind package.

• #d for the method's descriptor.
• #s for the method's signature.
• #r for the method's return type.
