Inherits
craft\base\MemoizableArray
Implements
ArrayAccess, Countable, IteratorAggregate, craft\base\Serializable
Since
3.5.8

MemoizableArray represents an array of values that need to be run through craft\helpers\ArrayHelper::where() or craft\helpers\ArrayHelper::firstWhere() repeatedly, where it could be beneficial if the results were memoized.

Any class properties that are set to an instance of this class should be excluded from class serialization:

php
public function __serialize()
{
    $vars = get_object_vars($this);
    unset($vars['myMemoizedPropertyName'];
    return $vars;
}
