DIContainerTrait

trait atk4\core\DIContainerTrait

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.
