Annotation Interface Advice.Origin

Enclosing class:
Advice
@Documented @Retention(RUNTIME) @Target(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 or MemberSubstitution.Origin. This annotation should be used only in combination with Advice.

      Returns the pattern the annotated parameter should be assigned. By default, the Annotation.toString() representation of the method is assigned. Alternatively, a pattern can be assigned where:
      • #t inserts the method's declaring type.
      • #m inserts the name of the method (<init> for constructors and <clinit> for static initializers).
      • #d for the method's descriptor.
      • #s for the method's signature.
      • #r for the method's return type.
      • #p for the property's name.
      Any other # character must be escaped by \ which can be escaped by itself. This property is ignored if the annotated parameter is of type Class.
