My recommendation would be to initialize the CFC with the string as an
initial argument, then call the different iterative methods without sending
the string over and over: just modify the variable within the CFC after
the init.
Ex:
<cfcomponent displayName="stringModder">
<cfset variables.myString = "" />
<cffunction name="init" access="public">
<cfargument name="myLongString" type="string" required="true" />
<cfset variables.myString = arguments.myLongString />
</cffunction>
<cffunction name="replaceSmartQuotes" access="public">
<cfset variables.myString = replaceList(variables.myString,
chr(145) &
"," chr(146), "','") />
</cffunction>
<cffunction name="replaceLineBreaks" access="public">
<cfset variables.myString = replace(variables.myString, chr(13)
&
chr(10), "<br />", "all") />
</cffunction>
</cfcomponent>
Then in the calling template:
<cfset stringObj = createObject("component",
"StringModder").init(form.bigTextValue) />
<cfset newString = stringObj.replaceSmartQuotes() />
<cfset newString = stringObj.replaceLineBreaks() />
etc ...

Subject: CFC arguments, passing large strings
Hello,
I have a CFC which does some string parsing to find and replace wildcards.
Within the CFC I am calling a method over and over and passing in the
entire
string as an argument. The method does some magic and returns a result.
The string could be a large (like a 2 page document) string and since its
being provided as an argument and is not inside an object/struct, I
believe
its passed by value. Which means, unless I am mistaken, if I call the
internal method 100 times, and pass in this large string am I creating a
ton
of overhead/memory usage?
Would I be better off creating a temp structure to hold the string and
other
arguments (which change with each iteration) and passing that into my
method
so its passed by reference instead?
What do you think?
