Everything you need for objects and models.

Overview of Methods
~~~~~~~~~~~~~~~~

\\nn\\t3::Obj()->merge(``$obj = NULL, $overlay = NULL``);
""""""""""""""""

Merge an array into an object

.. code-block:: php

	\nn\t3::Obj( \My\Doman\Model )->merge(['title'=>'New Title']);

This can even be used to write / üoverwrite FileReferences.
In this example, ``$data`` is merged with an existing model.
| ``falMedia`` is an ObjectStorage in the example. The first element in ``falMedia`` exists
already exists in the database (``uid = 12``). Only the title is updated here.
The second element in the array (without ``uid``) is new. For this, a new
| ``sys_file_reference`` is created in the database.

.. code-block:: php

	$data = [
	    'uid' => 10,
	    'title' => 'the title',
	    'falMedia' => [
	        ['uid'=>12, 'title'=>'1st image title'],
	        ['title'=>'NEW image title', 'publicUrl'=>'fileadmin/_tests/5e505e6b6143a.jpg'],
	    ]
	];
	$oldModel = $repository->findByUid( $data['uid'] );
	$mergedModel = \nn\t3::Obj($oldModel)->merge($data);

Note
In order to create a new model with data from an array there is
there is a method ``$newModel = \nn\t3::Convert($data)->toModel( \My\Model\Name::class );``

| ``@return Object``

\\nn\\t3::Obj()->isStorage(``$obj``);

return DataMap
.

\\nn\\t3::Obj()->toArray(``$obj, $depth = 3, $fields = [], $addClass = false``);
