I have a generic getter and setter that I use sometimes that looks like this:
<cffunction name="setProperty" access="public" returntype="void" output="False">
<cfargument name="PropertyName" type="string" required="true" />
<cfargument name="propertyValue" type="any" required="true" />
<cfargument name="PropertyType" type="string" required="false"
default="any">
<cfif arguments.propertyType NEQ "any" AND NOT
isValid(arguments.propertyType,propertyvalue)>
<cfthrow message="Invalid Type" detail="The value you provided
for
#arguments.propertyName# was not of type #arguments.propertyType#" />
<cfelse>
<cfset variables.instance.Property = arguments.Property />
</cfif>
</cffunction>
<cffunction name="getProperty" access="public" returntype="Any" output="false">
<cfargument name="PropertyName" type="string" required="true" />
<cfreturn variables.instance[arguments.propertyName] />
</cffunction>
That way you can set arbitraty values as properties, and get them back
out, as well as optional type checking.
I try to have getters and setters for everything, but if you had 100
different fields, this would be a good alternative.

Here's a typical getter:

My impression is that if a table has 100 fields, then there are going to
be 100 getters.
Q: Is it possible to write a generic getter that uses perhaps an array
index or some other voodoo method instead of hard coding 100 getters?
<cffunction name="getter" access="public" output="false"
returntype="any">
<cfargument name="Index" required="true">
<cfreturn variables.Array[arguments.Index] />
</cffunction>
If the number 100 makes you uncomfortable, substitute the number 50, or
25. Whatever number you're comfortable with. I know some people balk
at a table having 100 fields.
