/** |
|

|
|
|
* Vector is a stack-like collection. |
|
11
|
|
|
* |
|
12
|
|
|
* Like all objects in PHP, Vectors have reference-like semantics. When a |
|
13
|
|
|
* caller passes a Vector to a callee, the callee can modify the Vector and the |
|
14
|
|
|
* caller will see the changes. Vectors do not have "copy-on-write" semantics. |
|
15
|
|
|
* |
|
16
|
|
|
* Vectors only support integer keys. If a non-integer key is used, an |
|
17
|
|
|
* exception will be thrown. |
|
18
|
|
|
* |
|
19
|
|
|
* Vectors suoport "$m[$k]" style syntax for getting and setting values by |
|
20
|
|
|
* key. Vectors also support "isset($m[$k])" and "empty($m[$k])" syntax, and |
|
21
|
1 |
|
* they provide similar semantics as arrays. Elements can be added to a Vector |
|
22
|
|
|
* using "$m[] = .." syntax. |
|
23
|
1 |
|
* |
|
24
|
1 |
|
* Vectors do not support iterating while new elements are being added or |
|
25
|
|
|
* elements are being removed. When a new element is added or removed, all |
|
26
|
1 |
|
* iterators that point to the Vector shall be considered invalid. |
|
27
|
|
|
* |
|
28
|
|
|
* Vectors do not support taking elements by reference. If binding assignment |
|
29
|
17 |
|
* (=&) is used with an element of a Vector, or if an element of a Vector is |
|
30
|
|
|
* passed by reference, of if a Vector is used with foreach by reference, an |
|
31
|
17 |
|
* exception will be thrown. |
