Key to the UML Diagrams
These class diagrams use a subset of UML notation. Here is a brief key:
Classes and their methods are shown in rectangles:
Some methods and argument names are omitted for clarity. A third part, between the class name and methods, may be used for class variables. Underlined members are static.
Comments are shown in a rectangle with a turned down corner. A dotted line shows what the comment applies to.
