Re: [Reactor for CF] Re: MG Unity / Reactor - getModelGlue().getORMService()

Sun, 09 Jul 2006 17:25:10 -0700

I have a question about the singleton pattern. If I use ColdSpring to create singleton gateways of say my user and role gateways, if I call the gateway from multiple funtions within a CFC am I get a fresh copy of the gateway or record object each time? or do I need to assume that the object needs to be cleared for example on an iterator object.

Thanks for the clarification.

The syntax for what sean is suggesting looks like

<bean id="memberGateway" factory-bean="ormService" factory-method="createGateway">
        <constructor-arg name="objectAlias">
            <value>member</value>
        </constructor-arg>
    </bean>

that will create a singleton of your gateway that can be requested from coldspring or used in any other service object.

So you write that extra code into the database-specific generated
gateway CFC (in the data directory) and then Reactor automatically
uses that.

You can define the gateway object as a bean in the ColdSpring XML file
and tell it to use the reactoryFactory as a factory-bean and the
createGateway() as the factory-method (with a constructor-arg that is
the name of the table).
