Load class but not initiate it

[eluser]Rubain[/eluser]
Hi,

I was wondering, the $this->load->library() automatically initiates an object.

But I sometimes have to create a lot of objects. Is it a good style to put $this->load->library in a loop?

It feels like no-go. I could use the require_once and give in the relative path, but that doesn't seem to be the CI style also.

Is there an elegant way?

Thanks

There is no built in way to do this. Why would you want to load a library if you are not planning on using it?

So let's say I'm reading a lot of advertisements from some RSS feed.

Pseudocode:

Code:

foreach($advertisementsArray as $rawAdvertisement) {
     $this->load->library('advertisement', $rawAdvertisement, $outputArray[]);
}

This doesn't cause an overhead?

I was looking for something like

Code:

Load class Advertisement
foreach(...) {
   $outputArray[] = new Advertisement($rawAdvertisement);
}

EDIT:

Another example: I have a custom Exception, how do I load it, and throw it? This looks strange...

Code:

$this->load->library('BadConstructorCallException', array("reason" => "test"), 'ex');
throw $this->ex

Thanks!

You could load your library just before the loop starts and then in each repetition call a function that is defined within that library, passing your changing parameters.

[eluser]Rubain[/eluser]
So some kind of AdvertisementFactory, and call a function createAdvertisement(params)?

Is the way I use the exception ok?

Using your first structure is basically the same as the next. It performs one single in_array() check to see if the file is already loaded and only includes it if its not already in there. Really doesn't add that much overhead.

Code:

foreach($advertisementsArray as $rawAdvertisement) {
     $this->load->library('advertisement', $rawAdvertisement, $outputArray[]);
}

How would this work? Does your constructor return a string? Can they even do that? heh. Seems like odd syntax.

Code:

$outputArray[] = new Advertisement($rawAdvertisement);

[eluser]Rubain[/eluser]
Why do you think it returns a String? I didn't tested it.

Thanks for the answers! I didn't knew it was a good style of using it that much. I thought it was only used for singleton classes. If anybody knows a shorter way of throwing a homemade Exception, please tell me.

Thanks
