I just did a wee test, and - rather surprisingly to me - the currentRow
value seems to stick correctly when looping over a query and whilst
doing that, passing it lock-stock into another method.
CALLER.CFM
<cfscript>
q = queryNew("col");
for (i=1; i le 10; i=i+1){
queryAddRow(q);
querySetCell(q, "col", chr(64+i));
}
o = createObject("component", "c1");
q2 = o.f1(q);
writeOutput("#q2.currentRow# [although now it's reset]<br />");
</cfscript>
C1.CFC
<cfcomponent>
<cffunction name="f1" output="true">
<cfargument name="q">
<cfset var o = createObject("component", "c2")>
<cfloop query="arguments.q" startrow="3" endrow="8">
<cfoutput>f1: #arguments.q.currentRow#<br
/></cfoutput>
<cfset o.f2(arguments.q)>
<hr />
</cfloop>
<cfreturn arguments.q>
</cffunction>
</cfcomponent>
C2.CFC
<cfcomponent>
<cffunction name="f2" output="true" returntype="void">
<cfargument name="q">
<cfoutput>f2: #arguments.q.currentRow# [Note that it's
the same value as the calling iteration]<br /></cfoutput>
</cffunction>
</cfcomponent>
OUTPUT:
f1: 3
f2: 3 [Note that it's the same value as the calling iteration]
f1: 4
f2: 4 [Note that it's the same value as the calling iteration]
f1: 5
f2: 5 [Note that it's the same value as the calling iteration]
f1: 6
f2: 6 [Note that it's the same value as the calling iteration]
f1: 7
f2: 7 [Note that it's the same value as the calling iteration]
f1: 8
f2: 8 [Note that it's the same value as the calling iteration]
1 [although now it's reset]
