locking instantiated components

[Chuck1411]

are methods single threaded?

IE, when thread A calls method C, and thread B calls method C, of object O, do each have their own method? Or are they sharing the method and the same local variables? So do then the local variables need locking, or do/should I lock the component call, or just the method by name?

I'm a bit confused on this.

Local variables don't need locking. As long as you use the var keyword in your functions, you'll be fine.

If you "var" your function variables then you don't need to lock them. They will only exist inside the function and each thread that executes that function will basically have its own copy of the var'd variables. So they won't conflict with each other.

<cffunction name="YourFunction">
<cfset var YourVariable = "999" />
.....
</cffunction>
