|
* Data::Lift - Pass data around between various "actors". |
| 39 |
|
* |
| 40 |
|
* These "actors" are kinda plugin-modules |
| 41 |
|
* lying at "locations" and actually mungle the data. |
| 42 |
|
* |
| 43 |
|
* "Locations" are by now: |
| 44 |
|
* x local filesystem |
| 45 |
|
* o remote anything |
| 46 |
|
* |
| 47 |
|
* The "actors" require (by now) to be native php classes |
| 48 |
|
* having a method "perform". Please have a look at others |
| 49 |
|
* lying in the Data::Lift namespace at org.netfrag.glib to |
| 50 |
|
* get a picture of how to implement own "actors". |
