In Eclipse, the Java Method Override Indicator is the little upwards arrow next to a method in the Type Hierarchy view.
A solid arrow means a method overrides an existing method lower in the hierarchy.
What does the hollow arrow mean?
Do annotations effect either arrow?
The “hollow” or white, as I perceive it, arrow means that this method does not override a super class method but implements specified in an interface.
Annotations should not have anything to do with that. There is only a preference setting in the
java / editor / save actionssection that defines whether to automatically insert override annotations, but that is only semantically, but not technically related to the arrows mentioned
