CFINVOKE and its argumentcollection attribute

I'm passing a structure into a cfc using cfinvoke. I use argumentcollection attribute of the cfinvoke to pass this structure to my cfc (I don't know any other ways to do this, are there alternative?)
After doing some reading, I was able to pass my structure as explained in the code below.
My question is: Since all the arguments are now of type string then within my cfc I have no strcuture anymore, am I right?
If I still want to use a structure on my further coding I need to assemble a structure again using all the arguments that were passed??????

<cfset var result = "">
<cfset var myStruct = structNew()>
<cfset myStruct["a"] = 1>
<cfset myStruct["b"] = 2>
<cfset myStruct["c"] = 3>

<cfinvoke argumentcollection="#myStruct#" component="Comp2" method="handleArgCollection"
returnvariable="result" />

Within the cfc these are what I have:

<CFFUNCTION name="handleArgCollection">
<cfargument name="a" required="yes" type="string">
<cfargument name="b" required="yes" type="string">
<cfargument name="c" required="yes" type="string">

If I do something with myStruct, I got an error since myStruct is no longer exist (?)
So if I want to work with these argument parameters as a strcuture within this function do I have to re-create
a structure again using all those arguments???????


</CFFUNCTION>
