Re: [Reactor For CF] is the idea of an iterator in a gateway flawed?

[Dave Shuck]

I guess I need to go revisit the docs...  I don't believe I ever knew that existed other than iterators as properties of a record, but now it makes sense how that works under the hood.  Thanks for yet another thing for me to brag to all my non-Reactor friends about.  I swear, the longer I use it the more blown away I get.  I keep waiting for that "gotcha!" showstopper, but I am starting to be convinced it just isn't there.

Why do that when there already exists an Iterator object? 

 

<cfset ThingIterator = reactorFactory.createIterator("Thing") />

Subject: [Reactor For CF] is the idea of an iterator in a gateway flawed?

 

I was talking to a fellow developer about Reactor today and he asked if a gateway had the ability to return not only a query, but possibly an array of instantiated objects.  My knee jerk reaction was that this is normally not done and gateways normally return query recordsets, but I couldn't answer the "why not?".  Is it a bad idea for there to be some type of getIterator() in the gateway that accepted a query recordset along the lines of:

<cfset ThingGateway = Reactor.createGateway("Thing")  />
<cfset ThingIterator = ThingGateway.getIterator(ThingGateway.getAll()) />

I haven't really worked through this thoroughly and I am fairly certain that there must be a reason this isn't done, but could someone explain it?

If there isn't a reason this shouldn't be done, is this something that could be considered?

Thanks!
