Annotation Interface MemberSubstitution.FieldValue

Enclosing class:
MemberSubstitution
@Documented @Retention(RUNTIME) @Target({PARAMETER,METHOD,CONSTRUCTOR}) public static @interface MemberSubstitution.FieldValue

Indicates that the annotated parameter should be mapped to a field in the scope of the instrumented type.

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 FieldValue or Advice.FieldValue. This annotation should be used only in combination with MemberSubstitution.Substitution.Chain.Step.ForDelegation.
