|
16
|
|
|
* - access public properties |
|
17
|
|
|

|
18
|
|
|
* |
|
19
|
|
|
* - access protected properties that are visible on the subject class |
|
20
|
|
|
* -> use ReflectionPropertyAccess for performance |
|
21
|
|
|
* |
|
22
|
|
|
* - access private properties declared on the subject class |
|
23
|
|
|
* -> use ReflectionPropertyAccess for performance |
|
24
|
|
|
* |
|
25
|
|
|
* - access private properties that are declared on a base class of the subject class |
