this is probably way out there, and it's certainly far more confusing and
probably less maintainable and overall a bigger pain in the butt than your
proposed solution, but it's friday so what the hell:
i think you technically could do something like this:
you could have a new component that had these functions:
<cfcomponent hint="something i'm gonna inject">
<cffunction name="method1">
....args same as original method1's arguments ...
<cfset originalMethod1(arg1=arg1, arg2=arg2....)>
<cfset doMyDateStuff()>
</cffunction>
<cffunction name="doMyDateStuff">
... do my date stuff here ...
</cffunction>
</cfcomponent>
i'm assuming you at least have an instance of the original component
containing method 1, or access to that component, so:
in your code somewheres:
<cfset myInjector = createObject("component","MyInjector")>
Now's where it gets weird:
<!--- 'copy' method 1 into a new function --->
<cfset thirdPartyObject["originalMethod1"] = thirdPartyObject["method1"]>
<!--- override original method 1 with the method1 from your injector --->
<cfset thirdPartyObject["doMyDateStuff"] = myInjector["doMyDateStuff"]>
<cfset thirdPartyObject["method1"] = myInjector["method1"]>
when method1 is called, it's going to call the original method 1 that you
created by "copy", then it's going to call your date function.
Now, what I don't know is: A) whether this will work at all. probably not.
B) whether when you overwrite method1 it also technically overwrites
originalMethod1 since originalMethod1 just points to method 1. That's my
suspicion.
But hey, if you have nothing else to do and want to futz around with
creating hard to understand, unmaintainable method injection stuff that will
break whenever ThirdParty releases a new version, it might be fun to at
least give it a shot.
have a great day.
