[TYPO3-mvc] Get content elements from tt_content

[Matt Janus]

First of all I just wanted to say a big thank you to the group for the
support in helping me get my head round extbase and was hoping you
could help me out again.

I am creating an extension that will display content elements in tabs.
This plugin will use IRRE, so users can create tabs and then add
content elements to each tab.

I used the extension builder to create the domain model for the tab
with a simple title and a 1:n relation to the tt_content table.

The relevant sections of the model are below:

class Tx_myext_Domain_Model_Tab extends Tx_Extbase_DomainObject_AbstractEntity {
	/**
	 * Title
	 *
	 * @var string
	 */
	protected $title;
	/**
	 * Content Elements
	 *
	 * @var Tx_Extbase_Persistence_ObjectStorage<Tx_Contenttools_Domain_Model_Elements>
	 */
	protected $contentElements;

	/**
	 * Returns the title
	 *
	 * @return string $title
	 */
	public function getTitle() {
		return $this->title;
	}
	/**
	 * __construct
	 *
	 * @return void
	 */
	public function __construct() {
		//Do not remove the next line: It would break the functionality
		$this->initStorageObjects();
	}

	/**
	 * Initializes all Tx_Extbase_Persistence_ObjectStorage properties.
	 *
	 * @return void
	 */
	protected function initStorageObjects() {
		/**
		 * Do not modify this method!
		 * It will be rewritten on each save in the extension builder
		 * You may modify the constructor of this class instead
		 */
		$this->contentElements = new Tx_Extbase_Persistence_ObjectStorage();
	}
	/**
	 * Returns the contentElements
	 *
	 * @return Tx_Extbase_Persistence_ObjectStorage<Tx_Contenttools_Domain_Model_Elements>
$contentElements
	 */
	public function getContentElements() {
		return $this->contentElements;
	}
}

This also adds the following field to the tt_content table

#
# Table structure for table 'tt_content'
#
CREATE TABLE tt_content (
	tabs int(11) unsigned DEFAULT '0' NOT NULL
);

The backend works fine and allows me to create multiple tabs, each
with multiple content elements, my question is: how do I get the fully
rendered content elements in each tab object, that can then be passed
to a fluid template?

I believe this may have something to do with persistence mapping in
the TypoScript setup, but I am not sure how to go about this. Will
this just provide the raw information or will it provide the fully
rendered content element?

In a previous piBase extension this was done with $this->cObj->RECORDS

Any help and advice would be most appreciated.

All the best

Matt
