Is there a best practice for type validation when passing java objects
to a cffunction? I posted this on my blog, but figured I'd get a better
response here.
<cffunction name="doSomeThingWithJava" access="public"
returntype="void">
<cfargument name="javaObject" type="any" required="true" hint="I am
a java object, I must be of type: com.dross.myClass"/>
<cfset var someVar = 0/>
<cftry>
<cfif arguments.javaObject.getClass().getName() NEQ
"com.dross.myClass">
<cfthrow/>
</cfif>
<cfcatch>
<cfthrow
type="coldfusion.runtime.UDFMethod$InvalidArgumentTypeException"
message="The argument javaObject passed to function
doSomeThingWithJava() is not of type com.dross.myClass"
detail="Check and make sure the argument you are passing
is of the correct type"/>
</cfcatch>
</cftry>
<!--- function body --->
</cffunction>
Does anyone see a better way to do this?
