Re: [CFCDev] Top Ten Tips for Developing ColdFusion Components

[Matt Liotta]

The 'this' scope is public.  Anyone with a reference to the CFC, has a
reference to anything in the 'this' scope.  The 'variables' scope, on 
the
other hand, is private.  No one can access it, except the methods of 
the
CFC.  Both exist for the life of the CFC instance.  Usually you want 
to put
instance data in the 'variables' scope, so it's fully encapsulated by 
the
CFC.

However, if you provide a way to access data in the variables scope 
with a "getter" then you have provided a reference to that data right 
in the variables scope. In my book, if the data private to an object is 
mutatable then it is not encapsulated.
