How to understand type hierarchy feature in Eclipse for java project

For learning purposes, I am trying to import a java project, Lingpipe, into Eclipse. I used the “open Type Hierarchy” feature offered in Eclipse. The following figure is a screenshot. I do not quite understand what does those label mean, such as C with superscript S, or C with superscript A, or C with superscript F. In addition, some of them are marked with red. I use yellow color and red arrow line to mark some labels that I am referring to. In addition, how does this kind of type hierarchy help us to understand a java project?

The answer given by SimonC is correct but I guess you still need clarification on how it helps the user.

To be specific, C means Class F means Final Class S mean Static Class A means Abstract

all these notations helps user to indicate the class they are seeing is what kind of class. And Red dot is for Private Fields or Class or Method. Depending upon what object is referred. Same with Blue Triangle you see is for the package visibility.

Hope this helps.

The Eclipse icons are documented here: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Freference%2Fref-icons.htm

To answer your specific question, the C icon is a class, the supercsript A is abtract, S static, F final. The red square means it's private, the blue triangle is package scoped.

Amongst other things, the type hierarchy helps to understand what behaviour a class inherits from it's parent types.
