(FYI...we have a singleton "controller" that is decorated with all the services it
needs and stored in application scope)
controller
-- service1=persist1 (all S and P are tight coupled: 1=1)
-- service2=persist2
-- service3=persist3
=======================================
I really can't see many options to get these values down to where they're needed,
other than:
- get the controller to add them to every service method call (yuck!). this will then
be passed ot the persist.
- create specific methods that send the values from controller to service to
persist.the persist stores the values in it's variables scope.
but I can't help thinking there is a neater way to do this.
and if the persist calls to a .config file then that's breaking encapsulation (file
missing, etc)
this is the "create specific methods" idea: (note: the DSN is just an example)
<!--- in the controller.cfc --->
<cffunction name="setDSN" returntype="boolean">
<cfargument name="dsn" type="struct" required="true" />
<cfloop collection="#service#" item="serviceName">
<cfset bOK = service[serviceName].setDSN(arguments.dsn) />
</cfloop>
</cffunction>
<!--- in the service.cfc --->
<cffunction name="setDSN" returntype="boolean">
<cfargument name="dsn" type="struct" required="true" />
<cfset bOK = persist.setDSN(arguments.dsn)>
</cffunction>
<!--- and finally in the persist --->
<cffunction name="setDSN" returntype="boolean">
<cfargument name="dsn" type="struct" required="true" />
<cfset variables._dsn = arguments.dsn />
<cfreturn true />
</cffunction>
