How to get Annotations from IField and IMethod? [message #197972]

Hi,

is there a way to get Annotations from an IField or IMethod?
Something like the getAnnotations() method of java.lang.reflect.Field?

Greetings,

Jan

No, you have to parse the compilation unit of the IMember and then use an
AST visitor

But this is incredibly slow, and I need this information all the time. I
believe the IMember interface should directly offer the annotation
information. Is there a reason why this is not provided, or is it just not
implemented yet?

The java model only provides structural information. Annotations are
technically considered as extended modifiers.
By the way, parsing a cu without resolving bindings is amazingly fast, if
you don't need fully resolved type information.

Yes. But why is it possible to optain ordinary modifiers, but not the
extended ones?

Nevertheless it is an O(n) operation perhaps with a disk access, where it
could be in O(1).

But thanks for the answer. I perhaps file a feature request.
