Does anyone know if there are bugs in the duplicate() function?
I am having some trouble passing some simple but large struct arrays (e.g.
array[index]=struct[]), but the keys seem to get randomly confused, what
seems to be happening is that a date value will be randomly replaced by a
struct from another index or vice versa.
I am pointing this to the duplicate function as I have made a "deep copy"
function that does the job of duplicate() successfully, but is about 50
times slower (40-50ms vs. 2000-3000 ms). I have also used the WDDX parse
out-in method successfully, and while being faster than recursive method, it
is slow aswell.
Here is the function
<cffunction name="deepCopy" access="private">
<cfargument name="object" required="true">
<cfargument name="methodType" default="WDDX">
<cfset var returnValue="">
<cfset var returnType="">
<cfset var timer=getTickCount()>
<cfset var tmp="">
<cfif methodType IS "DUPLICATE">
<!--- AVERAGE TIME = 40ms --->
<cfset returnValue=duplicate(object)>
<cftrace text="deepCopy [DUPLICATE] =
#round(getTickCount()-timer)#ms"></cftrace>
<cfelseif methodType IS "WDDX">
<!--- AVERAGE TIME = 1800ms --->
<cfwddx action="CFML2WDDX" input="#object#"
output="tmp">
<cfwddx action="WDDX2CFML" input="#tmp#"
output="returnValue">
<cftrace text="deepCopy [WDDX] =
#round(getTickCount()-timer)#ms"></cftrace>
<cfelseif methodType IS "RECURSIVE">
<!--- AVERAGE TIME = 2400ms --->
<cfscript>
if (isSimpleValue(object)) {
returnValue=object;
returnType ="simple";
} else if (isStruct(object)) {
returnValue=structNew();
returnType ="struct";
for (i in object) {
returnValue[i]=deepCopy(object[i],methodType);
}
} else if (isArray(object)) {
returnValue=arrayNew(1);
returnType ="array";
for (i=1; i LTE arrayLen(object); i=i+1) {
returnValue[i]=deepCopy(object[i],methodType);
}
} else {
returnValue=object;
returnType ="other";
}
</cfscript>
<cftrace text="deepCopy [RECURSIVE] =
#round(getTickCount()-timer)#ms"></cftrace>
</cfif>
<cfreturn returnValue>
</cffunction>
Any ideas or advice?
Thanks
Joel
