Hi Guyz,
I've implemented a session based shopping cart with the following
components.
1) CartItem - ProductId, Name, Color, Cost etc with Getter and Setter
methods
2) Cart - An array of CartItem with AddCartItem, GetCartItems,
RemoveCartItem, etc methods
3) CartManager - Session facade that controls access to the Cart stored in
Session
CartManager has the following method to allow me to retrieve an Array of
CartItems from the session.
<cffunction name="GetCartItems" access="public" returntype="array"
output="false">
<cflock scope="Session" timeout="10" type="readonly">
<cfreturn Session.Cart.GetCartItems() />
</cflock>
</cffunction>
So my question is this. If I code Items = CartManager.GetCartItems() is it
safe to use the Array of CartItems now that I am no longer inside the lock?
For example, can I safely call Items[1].GetColor() or
Items[1].SetColor(color)?
Cheers, Pete (aka lad4bear)
