/** |
|
17
|
|
|
* Base singleton class of the MidCOM sessioning service. |
|
18
|
|
|
* |
|
19
|
|
|
* This is a singleton class, that is accessible through the MidCOM Service |
|
20
|
|
|
* infrastructure. It manages session data of MidCOM driven applications. |
|
21
|
|
|
* |
|
22
|
|
|
* This class provides a generic interface to store keyed session values in the |
|
23
|
|
|
* domain of the corresponding component. |
|
24
|
|
|
* |
|
25
|
|
|
* All requests involving this service will always be flagged as no_cache. |
|
26
|
|
|
* |
|
27
|
|
|
* If you store class instances within a session, which is perfectly safe in |
|
28
|
|
|
* general, there are known problems due to the fact, that a class declaration |
|
29
|
|
|
* has to be available before it can be deserialized. As PHP sessioning does this |
|
30
|
|
|
* deserialization automatically, this might fail with MidCOM, where the sequence |
|
31
|
|
|
* in which the code gets loaded and the sessioning gets started up is actually |
|
32
|
|
|
* undefined. To get around this problems, the sessioning system stores not the |
|
33
|
|
|
* actual data in the sessioning array, but a serialized string of the data, which |
|
34
|
|
|
* can always be deserialized on PHP sessioning startup (its a string after all). |
|
35
|
|
|
* This has an important implication though: The sessioning system always stores |
|
36
|
|
|
* copies of the data, not references. So if you put something in to the session |
|
37
|
|
|
* store and modify it afterwards, this change will not be reflected in the |
|
38
|
|
|
* sessioning store. |
|
39
|
|
|
* |
|
40
|
|
|
* <b>Important:</b> |
|
41
|
|
|
* |
|
42
|
|
|
* Do <b>never</b> create an instance of this class directly. This is handled |
|
43
|
|
|
* by the framework. Instead use midcom_service_session which ensures the |
|
44
|
|
|
* singleton pattern. |
|
45
|
|
|
* |
|
46
|
|
|
* Do <b>never</b> work directly with the $_SESSION["midcom_session_data"] |
|
47
|
|
|
* variable, this is a 100% must-not, as this will break functionality. |
