That's possible... Not what I had in mind, but it's possible... It
doesn't encapsulate the instructions the way I was imagining. Here's a
crude example (pardon the lack of appropriate i18n, etc.):
<cfset item = session.cart.getHeadItem()>
<cfloop condition="isObject(item)">
<tr>
<td>#item.getName()#</td>
<td>#item.getQty()#</td>
<td>$#item.getPrice()#</td>
<td>$#item.getSubtotal()#</td>
</tr>
<cfset item = item.getNextItem()>
</cfloop>
comparable array version
<cfloop index="x" from="1" to="#arraylen(session.cart)#">
<cfset item = session.cart[x]>
<tr>
<td>#item.getName()#</td>
<td>#item.getQty()#</td>
<td>$#item.getPrice()#</td>
<td>$#item.getSubtotal()#</td>
</tr>
</cfloop>
I'm not sure if this makes any sense, but I kinda like the
encapsulation of the former -- it seems cleaner to me... Even if I
wrapped the latter in a separate CFC to manage a java Vector I still
wouldn't get that same kind of encapsulation.
