|
* This implementation accesses properties through reflection. |
|
10
|
|
|
* |
|
11
|
|
|
* This is a medium speed accessor which less limitation. It will also be the most used one since most |
|
12
|
|
|
* class properties are protected or private. |
|
13
|
|
|

|
14

|
15
|
|
|
* What can it do? |
|
16
|
|
|
* |
|
17
|
|
|
* - access public properties (you should use PublicPropertyAccess instead for performance) |
|
18
|
|
|
* |
|
19
|
|
|
* - access protected properties that are visible on the subject class |
|
20
|
|
|
* |
|
21
|
|
|
* - access private properties declared on the subject class |
|
22
|
|
|
* |
|
23
|
|
|
* What can it NOT do? |
|
24
|
|
|
* |
|
25
|
|
|
* - access private properties that are declared on a base class of the subject class |
|
26
|
|
|
* -> use ScopedPropertyAccess then which is the slowest accessor |
