RE: [CFCDev] Race Conditions when scoped in the Application variable

Kerry,

The object in question was an example. However I will be holding a collection of this info hence my question in the first place.

My main query was really why is the factory performing crud operations.

The meaning of this line is to show the factory returning a new instance of the object that does the crud operations so that there is no need for any locking.

Kerry,

First of all I type this in a bit of a hurry, so yeah it userFactory is not a function. Secondly as I described the object is a user object that will be held in memory so the scope form has nothing to do with this scenario so why give that to me as an example?

<cfset Application.userFactory = CreateObject(‘component’,’com.framework.user’) />

Is my initialisation of the factory.

<cfset Application.userFactory.AddUser(UserObject) />

<cfset Application.userFactory.DeleteUSer(UserObject) />

Gets used else where in the application when I need to add a new user that has logged in, or delete a user when they have logged out.

UserObject is a copy of structure of information that will hold user information.

So in my example it was very close to you

<cfset UserObject = application.userFactory.newUser()>

But thanks for your input any how, even though it didn’t answer what I was asking for.

Regards,

Andrew Scott

<cfset Application.userFactory = CreateObject(‘component’,’com.framework.user’) />

<cfset Application.userFactory().AddUser(UserObject) />

<cfset Application.userFactory().DeleteUSer(UserObject) />

bit confused by this code.

1) userFactory is not a function.

2) why is the factory performing CRUD operations? the factory should return an instance of the user component?

<cfset Application.userFactory = CreateObject(‘component’,’com.framework.userfactory’) />

<cfset variables.oUser = application.userFactory.newUser()>

<cfset variables.oUser.AddUser(argumentCollection=form) />

<cfset variables.oUser.DeleteUser(User_ID=form.user_id) />

Ok I am looking at a solution where I am keeping track of certain details that users do on the website. I was looking at creating it in the application scope. But I am unclear on a few things.

If I set up the scop in this manner.

<cfset Application.userFactory = CreateObject(‘component’,’com.framework.user’) />

Now through the code I will make reference to it like such.

<cfset Application.userFactory().AddUser(UserObject) />

<cfset Application.userFactory().DeleteUSer(UserObject) />

Now what I am not clear on is the internals of this, for example. The user object has a structured array that contains the information for all users logged into the system, and other tid bits of information. My question is, should I be locking access to variables when setting inside or not?

This is where I am a little unclear, I have had a look at the Mach-II framework and it doesn’t seem to do this. Except when setting the application.userfactory in the application scope to begin with.

Could someone give me a little more run down on this, as well as hopefully clear the process up a little more for me as well.
