Yep, January meeting is on 1/11 and we'll be talking about open source
projects in the ColdFusion world.
As for CFCs, basically what I'm saying is if you do the following,
you're going to be creating and destroying your object every time,
which is really inefficient:
<cfinvoke component="MyCFC" method="getSomeStuff" returnvariable="someStuff" />
<cfinvoke component="MyCFC" method="getSomeOtherStuff"
returnvariable="someOtherStuff" />
What that does is create, call, destroy, then create, call, destroy
again, which has unnecessary overhead associated with it. If you're
going to use an object a few times, you want to instantiate the object
using CreateObject or cfobject, then call the methods:
<cfset myObject = CreateObject("component", "MyCFC") />
<cfset someStuff = myObject.getSomeStuff() />
<cfset someOtherStuff = myObject.getSomeOtherStuff() />
Because you only create the object once, there's less overhead
involved, although once you create it it takes up memory of course.
You have to adjust any of this stuff to your particular situation.
Let me know if that didn't answer your question.
