| #summary Considerations when developing and reviewing source code. |
| |
| = Sweeping guidelines = |
| |
| # Don't introduce code provisionally. Only insert code that is being used for a purpose. Corollary: Develop using vertical slices, instead of horizontal slices. |
| # Each CL does one thing. Don't insert refactorings into functional changes and vice-versa. |
| # Aim for small CLs. |
| # Don't send out "try-things-out" CLs. |
| # Make CLs direct and concrete. |
| * no unneccesary indirection; keep hierarchies shallow |
| * put String constants directly in code instead of having unnecessary finals declared |
| # Prefer plain/idiomatic/obvious over clever. |
| # Name things! |
| * make specific exception classes |
| * don't use "abstract" in class name |
| * don't use "impl" in class name |
| * name sub-blocks of code by converting to methods |

| = Particular considerations = |
| |
| # Is the code thread safe? Read your code and check whether your code behaves well when multiple methods of an instance are executing simultaneously. Avoid settors to make classes immutable. |
| # Was equals considered? |
| # Was hashCode considered? |
| # Were exceptions considered? Are exceptions scoped precisely and accurately? |
| # Was toString considered? toString is helpful for testing and debugging. |
| # Does the code call exit? Don't call exit as it makes code un-libifable and means shutdown sequenceing is not understood. |
| # Please provide sufficient tests. |
| # BufferedImage is TYPE_INT_RGB |
| # Gui use done with SwingUtilities.invokeLater () so that SwingUtilities.isEventDispatchThread() |
| # Usually if a class uses Random, it is parameterizable on Random |
| # Was use of System.out and System.err considered? Be very selective about putting information on these channels. Quite possibly never use them for communicating information. |
| # Watch out for autoboxing and varargs producing undesireable behaviour. |
| # Consider public and final modifiers on classes and methods. |
| # Add javadoc |
