It helps me (but isn't completely correct) to think of the createObject()
call as a "blank CFC". The init() call populates it to make it useful.
A metaphor might be a bunch of blank paper - all different sizes and shapes.
You first choose one (deciding that piece has the properties you need), then
your write your note on it (deciding what, specifically that appropriate
piece will do).
Assume a "Recipe" CFC. The CFC instance begins as a blank index card. Your
init() adds (via arguments, a database call or whatever) three properties:
"Name", "Ingredients" and "Directions".
In pseudo code it might look like:
<cfset MyRecipe = CreateObject("Get One Blank 4x5 Index Card").init("Write
Recipe for Ice Cubes on Index Card") />
<cfoutput>
<h1>#MyRecipe.getName()#</h1>
<p>#MyRecipe.getIngrediants()#</p>
<p>#MyRecipe.getDirections()#</p>
</cfoutput>
(The above brought to you by the Coalition to Prevent the Proliferation of
Automobile Metaphors in Technical Discussion.)
