Got it you guys,
I had the path name incorrectly
pointed...derr...below is the correct path name...Thanks everyone!!
<cfcomponent
extends="Web_Test_2.Web_Can.Core_CFC.comp_Name">
<cffunction
name="DisplayName" access="public"
returntype="string">
<cfset
myResult="Jeremy">
<cfreturn
myResult>
</cffunction>
</cfcomponent>
I have another question or two.....
When you say "what does the inheriting
component look like" - what do you mean ?
The code you have presented is basically "right" in terms of inheriting
CFC's. If you now call the "menu" method in the derived class, it should
result in the parent class method being called (because you have not defined
an override in the child class - because it is commented out). If you
comment out the derived classes "menu" method, then this would be called
instead.
What are you wanting the
relationship to do?
NOTE: There is
no "super class" calling ability in CFC's (that I can find). This means
you can't override a method in a child class and then call the original method
back in the parent from the overriding method.
If anyone out there can contradict me on this, I would
be happy. The only mechanism I can see of doing this is to use a unique
naming convention in ancestor classes, then create "shell" calls that you
override, and then you can call the "base" class method using the unique
names. To add additional protection to these ancestor methods, you would
set their ACCESS to PACKAGE and then place all inheriting classes in the same
directory (package) as the ancestor class (components outside of the directory
cannot access methods with the PACKAGE access). And if you want an
overridable method that does NOT allow access to the base class
implementation, then set the ACCESS to PRIVATE but still call it from the
"shell" method.
