If you're component is stateful, you'll want to invoke methods on the
same instance of the component instead of continually creating new
instances.
<!--- Instantiate a component that adds two numbers --->
<cfset myAdder = createObject("component", "addsTwoNumbers") />
<!--- Set first number --->
<cfinvoke
component="#myAdder#"
method="setNumberOne"
<cfinvokeargument
name="number"
value="2">
</cfinvoke>
<!--- Set second number --->
<cfinvoke
component="#myAdder#"
method="setNumberTwo"
<cfinvokeargument
name="number"
value="3">
</cfinvoke>
<!--- Get sum --->
<cfinvoke
component="#myAdder#"
method="getSum"
returnVariable="sum"
</cfinvoke>
<!--- Displays five --->
<cfoutput>#sum#</cfoutput>
There's a few different ways to write this....I'd probably use:
<cfset myAdder = createObject("component", "addsTwoNumbers") />
<cfset myAdder.SetNumberOne(2) />
<cfset myAdder.SetNumberTwo(3) />
<cfoutput>#myAdder.getSum()#</cfoutput>
