Annotation Interface FieldValue
Assigns the value of a field of the instrumented type to the annotated parameter. For a binding to be valid,
the instrumented type must be able to access a field of the given name. Also, the parameter's type must be
assignable to the given field. For attempting a type casting, the RuntimeType
annotation can be
applied to the parameter.
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.FieldValue
or
MemberSubstitution.FieldValue
. This annotation should be used with
MethodDelegation
only.
