Meaning of icons in Eclipse Type Hierarchy window

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 eit开发者_开发知识库her 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 actions section that defines whether to automatically insert override annotations, but that is only semantically, but not technically related to the arrows mentioned
