What do all these little symbols mean?

Many of the methods in the SystemBrowser (my current default), have symbols next to them. As far as I can tell, they relate to whether a method is inherited, overridden, or something else! The rules seem to be:

• Nothing: new method in this chain, i.e. the method could exist in other classes but not in this particular chain of inheritance.


• Upward orange triangle: method is inherited and overridden in this class


• Downward orange triangle: method is overridden in a subclass


• Two orange triangles (up and down): overrides and is overridden in a subclass


• Green up arrow: calls the same method in its super class


• Blue triangle: Self should not implement or subClassResponsibility


• Green plus: don't know, can't work this one out


• Red flag: has a halt message in the code


• Spanner: shows that the code needs to be returned to, i.e. under construction

Need to check this stuff on the beginners' list
