Jonathon,
You're on the right track, but it's much easier than that. Here's some play
code I just whipped up:
<cfscript>
function getVariablesExternal() {return variables;}
function methodToInject() {return "This method was Injected";}
myCFC = createObject("component","test").init(); // get component
myCFC.getVariables = getVariablesExternal; // inject variable scope getter
into "this" scope
myCFC.getVariables().injectedMethod = methodToInject; // inject a method
into CFC "variables" scope
myCFC.getVariables().this.injectedMethod = methodToInject; // also into
public "this" scope
writeOutput( myCFC.getVariables().privateMethod() ); // call private
method from test.cfc
writeOutput( myCFC.injectedMethod() ); // call injected method
</cfscript>
It's really amazing the things you can do with this stuff :D
PS here's my test.cfc:
<cfcomponent>
<cffunction name="init" access="public">
<cfreturn this>
</cffunction>
<cffunction name="privateMethod" access="private">
<cfreturn "This is a Private Method!">
</cffunction>
<cffunction name="publicMethod" access="public">
<cfreturn "This is a Public Method!">
</cffunction>
</cfcomponent>
This is actually the concept of mix-ins, there has been some more formal
code written about it, but you can do it like this, like a cfinclude file
(even with a dynamic file name) from inside the CFC, you can get a struct of
functions and loop over them, calling each or injecting them elsewhere, you
can have a mixin() method that takes a function as an argument, and so on
and so on. Really, lots of fun things here!
