Re: [WebMacro-user] Accessing property via "Unary Accessor"

[Keats K. <ke...@xa...>]

Actually you're not completely correct.  A public variable name "title" 
would be referred to as $obj.title.  This is the point Eric was trying 
to make; WM allows you to be completely unambiguous about the property 
you are referring to.  You can have a fields called "title", "Title", 
"TITLE", or accessors called "gettitle", "getTitle", getTITLE".  So the 
reason you refer to a property as "Title" is that you are generally 
referring to the "getTitle" accessor, not the non-public "title" member 
variable.

It's also worthwhile to note that WM pre-dates JSP, so the property 
naming conventions for Java scripting were not well established at that 
time.  Personally I prefer the WM approach, for the reasons mentioned, 
and also aesthetically, but it's basically just a religious preference.  
Just be glad you're not using C# which got it all mixed up. ;-}
