Annotation Type FieldGetterHandle
-
@Documented @Retention(RUNTIME) @Target(PARAMETER) public @interface FieldGetterHandle
Assigns a
java.lang.invoke.MethodHandle
to the annotated parameter which represents a getter of the represented field. For a binding to be valid, the instrumented type must be able to access a field of the given name.Setting
value()
is optional. If the value is not set, the field value attempts to bind a setter's or getter's field if the intercepted method is an accessor method. Otherwise, the binding renders the target method to be an illegal candidate for binding.Important: Don't confuse this annotation with
Advice.FieldGetterHandle
orMemberSubstitution.FieldSetterHandle
. This annotation should be used withMethodDelegation
only.
