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\.
