Annotation Type Advice.FieldGetterHandle

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

Indicates that the annotated parameter should be mapped to a java.lang.invoke.MethodHandle representing a field getter.

Setting Advice.FieldValue.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: Parameters with this option must not be used when from a constructor in combination with Advice.OnMethodEnter and a non-static field where the this reference is not available.

Important: Don't confuse this annotation with FieldGetterHandle or MemberSubstitution.FieldGetterHandle. This annotation should be used only in combination with Advice.
