Functionality of LoadHistory from JModelLegacy

Question

This is connected to the earlier post I mentioned:

Now that I found the loadhistory function, I was wondering, how was it able to be called directly from the URL below:

/BDES3/administrator/index.php?option=com_content&task=article.loadhistory&version_id=1

in the part : &task=article.loadhistory

article is the controller right? and loadhistory is the controller function?

is a statement saying :

"If your request contained a 'task=jump' parameter the controller would have tried to call a method (function) named 'jump' in your controller class"

But when i viewed the article class under the controllers folder, there was no loadhistory function. It was found in the JModelLegacy Class.

How is this possible? I am planning on re-using the loadhistory functionality on a custom component that we're trying to build.

Yes you are right. The first part it the controller name and the second part is the method name.

But when i viewed the article class under the controllers folder, there was no loadhistory function. It was found in the JModelLegacy Class.

That is because it is located in the parent JControllerForm class.

Do you mean to re-use the same method? Yes if your class will inherit from JControllerForm. Otherwise you will need to make your own method (of course you can just copy the existing and modify for your needs).
