/** |
| 16 |
* LinkBuilder |
| 17 |
* |
| 18 |
* This implements a persistent storage for variables needed at links |
| 19 |
* where unique id are used to different the temporarly stored variables |
| 20 |
* |
| 21 |
* It's similar to James A. Duncan's "Pixie", see |
| 22 |
* Pixie - The magic data pixie |
| 23 |
* http://search.cpan.org/author/JDUNCAN/Pixie-2.06/ |
| 24 |
* But that one - of course - is somehow more sophisticated. It offers multiple |
| 25 |
* storage implementations for your data payloads and also seems to implement |
| 26 |
* some locking strategies. (Pixie::LockStrat & Co.) |
| 27 |
* |
| 28 |
* However, their core concepts are comparable: |
| 29 |
* Expect an arbitrary variable as "data container" (hash prefered!?) and save it |
| 30 |
* away assigning an unique identifier for the slot the actual payload lives inside |
| 31 |
* the storage. |
| 32 |
* This identifier gets returned as a result of the save/store/create operation and |
| 33 |
* can be used later to get to the persisted data via a load/restore/retrieve operation. |
| 34 |
* |
| 35 |
* @todo prevent HUGE SESSION! delete session entry after all needed stuff(entries) is loaded to!! |
| 36 |
* @todo is php::CreateGUID expensive? review! |
| 37 |
* @todo maybe refactor to Data::PhpSpace::Persistent, which inherits from Data::PhpSpace? |
