/** |

17
|
|
|
* Create dynamic references array from name-reference pairs. |
|
18
|
|
|
* |
|
19
|
|
|
* For example if we want to define a set of named dynamic references, usually |
|
20
|
|
|
* it is done as: |
|
21
|
|
|
* |
|
22
|
|
|
* ```php |
|
23
|
|
|
* // di-web.php |
|
24
|
|
|
* |
|
25
|
|
|
* ContentNegotiator::class => [ |
|
26
|
|
|
* '__construct()' => [ |
|
27
|
|
|
* 'contentFormatters' => [ |
|
28
|
|
|
* 'text/html' => DynamicReference::to(HtmlDataResponseFormatter::class), |
|
29
|
|
|
* 'application/xml' => DynamicReference::to(XmlDataResponseFormatter::class), |
|
30
|
|
|
* 'application/json' => DynamicReference::to(JsonDataResponseFormatter::class), |
|
31
|
|
|
* ], |
|
32
|
|
|
* ], |
|
33
|
|
|
* ], |
|
34
|
|
|
* ``` |
|
35
|
|
|
* |
|
36
|
|
|
* That is not very convenient, so we can define formatters in a separate config and without explicitly using |
|
37
|
|
|
* `DynamicReference::to()` for each formatter: |
|
38
|
|
|
* |
|
39
|
|
|
* ```php |
|
40
|
|
|
* // params.php |
|
41
|
|
|
* return [ |
|
42
|
|
|
* 'yiisoft/data-response' => [ |
|
43
|
|
|
* 'contentFormatters' => [ |
|
44
|
|
|
* 'text/html' => HtmlDataResponseFormatter::class, |
|
45
|
|
|
* 'application/xml' => XmlDataResponseFormatter::class, |
|
46
|
|
|
* 'application/json' => JsonDataResponseFormatter::class, |
|
47
|
|
|
* ], |
|
48
|
|
|
* ], |
|
49
|
|
|
* ]; |
|
50
|
|
|
* ``` |
|
51
|
|
|
* |
|
52
|
|
|
* Then we can use it like the following: |
|
53
|
|
|
* |
|
54
|
|
|
* ```php |
|
55
|
|
|
* // di-web.php |
|
56
|
|
|
* |
|
57
|
|
|
* ContentNegotiator::class => [ |
|
58
|
|
|
* '__construct()' => [ |
|
59
|
|
|
* 'contentFormatters' => |
|
60
|
|
|
* DynamicReferencesArray::from($params['yiisoft/data-response']['contentFormatters']), |
|
61
|
|
|
* ], |
|
62
|
|
|
* ], |
|
63
|
|
|
* ``` |
|
64
|
|
|
* |
|
65
|
|
|
* @param array $definitions Name-reference pairs. |
|
66
|
|
|
* |
|
67
|
|
|
* @throws InvalidConfigException |
|
68
|
|
|
* |
|
69
|
|
|
* @return DynamicReference[] |
|
