Sanders Tue, 31 Mar 2009 18:20:50 +0000 http://www.as3dp.com/?p=836#comment-1934 Hi Tf, Your point is a valid one, but I've decided that since Abstract classes are essentially referenced as an interface, that they too can be prefaced by an 'I', and that reminds me not to instantiate them. This particular Abstract class is pretty loaded up; and so it was doubly important not to forget. A point that I've come to understand is that "interface" is more important as a term denoting the methods, properties and signature of a class than the ActionScript statement "interface" used to denote those characteristics. When all you're really using in an Abstract class is its interface (since you never instantiate it), it too is essentially an interface. Does that help explain it? Thanks for your comment, and no question is dumb except those that are unasked. Take care, Bill Hi Tf,

Your point is a valid one, but I’ve decided that since Abstract classes are essentially referenced as an interface, that they too can be prefaced by an ‘I’, and that reminds me not to instantiate them. This particular Abstract class is pretty loaded up; and so it was doubly important not to forget.

A point that I’ve come to understand is that “interface” is more important as a term denoting the methods, properties and signature of a class than the ActionScript statement “interface” used to denote those characteristics. When all you’re really using in an Abstract class is its interface (since you never instantiate it), it too is essentially an interface.

Does that help explain it?

Thanks for your comment, and no question is dumb except those that are unasked.

Take care,
Bill

I was informed by assorted waggling fingers that the I-prefix was reserved for interfaces. That's it for me, just a dumb question.
