Bug 93564 Preference setting for @Override annotation
20050503 The story for adding the @Override annotation is currently abit confusing. Only the override dialog offers to add the annotation, all other override actions (quick fix, code assist) don't add it. A code style preference setting should be added to be used by all of them and the override wizatd checkbox removed. Requesting PMC approval for new the preference constant /** * A named preference that controls whether to add a override annotation for newly created methods * <p> * Value is of type <code>Boolean</code>. * </p> * @since 3.1 */ PreferenceConstants.CODEGEN_USE_OVERRIDE_ANNOTATION
