Another way to illustrate what I mean:
The feature will be used /to annotate/ (add metadata) and the so
/annotated/ data has additional /attributes/ afterwards.
Trying building the sentence if the feature is called /attributes/.
@entity
@invariant
final class A {
@inject
private static $x;
@test
public memoized function f(){}
}
r = reflect A
r.getModifiers = [ final ]
r.getAnnotations = [ entity, invariant ]
r.getAttributes = [ final, entity, invariant ]
r = reflect A.x
r.getModifiers = [ private, static ]
r.getAnnotations = [ inject ]
r.getAttributes = [ private, static, inject ]
r = reflect A.f
r.getModifiers = [ public, memoized ]
r.getAnnotations = [ test ]
r.getAttributes = [ public, memoized, test ]
Note that there are programming languages that allow adding of metadata
solely via annotations: Ceylon. No matter the data to annotate. Hence,
in Ceylon no differentiation would be made between modifiers and
annotations. However, one could check the actual annotation type to
determine what it is.
