( #3333=superdoc: print w/replies, xml ) Need Help??
As you point out, this isn't really the issue - the issue is accidental interference rather than deliberate trespass.
Deliberate trespass in your own codebase isn't something you fix in software, it's something you fix by going over to someone's cube and removing their mouse balls until they get the point. Anyhow, if you can't trust your fellow coders to not play symbol table / reflection / etc type games, you have problems! So folks think they have encapsulation, but they don't, and they think they have loose coupling, but they don't.

Encapsulation is mainly in existance to enforce clean boundaries between objects, and ideally these boundaries should be limited to a very small list of methods and few variables, such that changes in the objects don't break programs.

Furthermore, encapsulation can be broken with no access to variables, by virtue of having trivial getter/setter methods encapsulation IS broken, because the parameters of your object can be tweaked without asking the object nicely. Most folks already know this, but at least in the java world, many don't!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
