DIContainerTrait
================


.. php:namespace:: atk4\core

.. php:trait:: DIContainerTrait


	.. rst-class:: phpdoc-description
	
		| A class with this trait will have setDefaults\(\) method that can
		| be passed list of default properties\.
		
		| $view\-\>setDefaults\(\[\'ui\' =\> \'segment\'\]\);
		| 
		| Typically you would want to do that inside your constructor\. The
		| default handling of the properties is:
		| 
		|  \- only apply properties that are defined
		|  \- only set property if it\'s current value is null
		|  \- ignore defaults that have null value
		|  \- if existing property and default have array, then both arrays will be merged
		| 
		| Several classes may opt to extend setDefaults, for example in Agile UI
		| setDefaults is extended to support classes and content:
		| 
		| $segment\-\>setDefaults\(\[\'Hello There\', \'red\', \'ui\'=\>\'segment\'\]\);
		| 
		| WARNING: Do not use this trait unless you have a lot of properties
		| to inject\. Also follow the guidelines on
		| https://github\.com/atk4/ui/wiki/Object\-Constructors
		| 
		| Relying on this trait excessively may cause anger management issues to
		| some code reviewers\.
