What happened to CFC forum?

[brettr_]

There use to be a CFC forum here. Has it been discontinued? Also, what use
are CFC access=package? The only example I've seen shows referencing a CFC via
full directory path dot notation. You can do that without access=package.
Comments? Thanks, Brett

available only to the component that declares the method, components that extend the component, or any other components in the package.

I don't follow what you mean by, 'available only to the component that declares the method'.

Please give me an example of what you would want to use a package.

[Buda123]

For example you have component 'users.cfc', and inside you have couple of
methods, search, insert, delete..... for example you are making insert to DB,
and you have html form, where user fill data and on click of submit button you
are calling 'users.cfc' and 'insert' method. To insert record you need to
generate primary key for new record, so you can make method 'makePK' inside the
same 'users.cfc'. Since that method is called only by methods inside
'users.cfc' and NOT by outside world. you can make it as 'package' so only
methods within 'users.cfc' can access it. This is just an example, I hope it
helps

Why not just declare makePK as private?

[Buda123]

well, if you declare it as private, you can access it only within that
particular component, and if it as a package you can use it within any
component in the same folder (without using extend attribute). That is main
difference.

I see. Is there an equivalent to package in Java? Package is the same as
declaring everything public as long as you stay in the same folder....correct?
You reference a comparison to extends. However, extend is more specific.
Package just seems to make everything open within the same folder that is
declared as package. Seems dangerous and may add complexity to your debugging.

I am not sure for Java, but yes you are right,

Given that, do you know of any real world application for 'package'? Also, it
doesn't seem Macromedia has done any type of enhancements for making CF and CFC
more object oriented. For example: - allowing a child to inherent from the
grandparant - constructor - destructor - protected or friend declaration -
shared declaration ...to start with. Just seems Macromedia isn't taking object
orientation seriously. What they have now is very peice mill...for lack of
better words.

[Buda123]

Nope, I never used package in real life ( I haven't found real need for that)
and exactly, even there is a bunch of realy cool features in new CF, Ithink
more Object Orienting will be realy nice add on to CF.
