org.apache.tapestry5.services.ClassTransformation.claimField()
Claims a field so as to ensure that only a single annotation is applied to any single field. When a transformation occurs (driven by a field annotation), the field is claimed (using the annotation object as the tag). If a field has multiple conflicting annotations, this will be discovered when the code attempts to claim the field a second time. @param fieldName the name of the field that is being claimed @param tag a non-null object that represents why the field is being tagged (this is typically a specific annotation on the field) @throws IllegalArgumentException if the fieldName does not correspond to a declared instance field @throws IllegalStateException if the field is already claimed for some other tag @deprecated Use {@link TransformField#claim(Object)} instead
