/** |
36
|
|
|
* Additive objects are subobjects in the API that don't have the same |
37
|
|
|
* semantics as most subobjects, which are fully replaced when they're set. |
38
|
|
|
* This is best illustrated by example. The `source` parameter sent when |
39
|
|
|
* updating a subscription is *not* additive; if we set it: |
40
|
|
|
* |
41
|
|
|
* source[object]=card&source[number]=123 |
42
|
|
|
* |
43
|
|
|
* We expect the old `source` object to have been overwritten completely. If |
44
|
|
|
* the previous source had an `address_state` key associated with it and we |
45
|
|
|
* didn't send one this time, that value of `address_state` is gone. |
46
|
|
|
* |
47
|
|
|
* By contrast, additive objects are those that will have new data added to |
48
|
|
|
* them while keeping any existing data in place. The only known case of its |
49
|
|
|
* use is for `metadata`, but it could in theory be more general. As an |
50
|
|
|
* example, say we have a `metadata` object that looks like this on the |
51
|
|
|
* server side: |
52
|
|
|
* |
53
|
|
|
* metadata = ["old" => "old_value"] |
54
|
|
|
* |
55
|
|
|
* If we update the object with `metadata[new]=new_value`, the server side |
56
|
|
|
* object now has *both* fields: |
57
|
|
|
* |
58
|
|
|
* metadata = ["old" => "old_value", "new" => "new_value"] |
59
|
|
|
* |
60
|
|
|
* This is okay in itself because usually users will want to treat it as |
61
|
|
|
* additive: |
62
|
|
|
* |
63
|
|
|
* $obj->metadata["new"] = "new_value"; |
64
|
|
|
* $obj->save(); |
65
|
|
|
* |
66
|
|
|
* However, in other cases, they may want to replace the entire existing |
67
|
|
|
* contents: |
68
|
|
|
* |
69
|
|
|
* $obj->metadata = ["new" => "new_value"]; |
70
|
|
|
* $obj->save(); |
71
|
|
|
* |
72
|
|
|
* This is where things get a little bit tricky because in order to clear |
73
|
|
|
* any old keys that may have existed, we actually have to send an explicit |
74
|
|
|
* empty string to the server. So the operation above would have to send |
75
|
|
|
* this form to get the intended behavior: |
76
|
|
|
* |
77
|
|
|
* metadata[old]=&metadata[new]=new_value |
78
|
|
|
* |
79
|
|
|
* This method allows us to track which parameters are considered additive, |
80
|
|
|
* and lets us behave correctly where appropriate when serializing |
81
|
|
|
* parameters to be sent. |
82
|
|

* |
83

* @return Util\Set Set of additive parameters |

It seems like the type of the argument is not accepted by the function/method which you are calling.
In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.
We suggest to add an explicit type cast like in the following example:
