Dear monks,

Often when writing code, i try to encapsulate the code in a class, library, package (depending on the language used) so that it can be reused if necessary.

Doing so i often find myself thinking about the same issues over and over again :

  • How much functionality should the library encapsulate ?
    Is it better to make ALL the functions that are related to a common goal available to the application programmer OR should i mask these behind 1 or 2 method calls ? The former will allow for greater flexibility (maybe unnecessary) , the latter will greatly simplify its usage. Or should i do both and really complicate things ?
  • Who is responsible for error handling and error resolving ?
    Should the library trap any foreseeable error and deal with it OR should this be left to the application programmer ?

    If there is a standard to writing libraries as to what you should expose and what not then i'ld like to hear about it...
