__construct() public method

public mixed __construct ( mixed $value, string\|null $type = null )
$value	mixed	The JSON content. It can be represented as an `array` of values; an instance which implements {@see \Yiisoft\Db\Expression\Value\Traversable} or {@see \Yiisoft\Db\Expression\Value\JsonSerializable} and represents an array of values; an instance of {@see \Yiisoft\Db\Expression\Value\QueryInterface} that represents an SQL sub-query; a valid JSON encoded array as a `string`, e.g. `'[1,2,3]'` or `'{"a":1,"b":2}'`; any other value compatible with {@see \json_encode()} input requirements.
$type	string\|null	Type of database column, value should be cast to. Defaults to `null`, meaning no explicit casting will be performed. This property is used only for DBMSs that support different types of JSON. For example, PostgresSQL has `json` and `jsonb` types.
