45 |
|
* Data::Lift - Pass data around between various "actors". |
46 |
|
* |
47 |
|
* These "actors" are kinda plugin-modules |
48 |
|
* lying at "locations" and actually mungle the data. |
49 |
|
* |
50 |
|
* "Locations" are by now: |
51 |
|
* x local filesystem |
52 |
|
* o remote anything |
53 |
|
* |
54 |
|
* The "actors" require (by now) to be native php classes |
55 |
|
* having a method "perform". Please have a look at others |
56 |
|
* lying in the Data::Lift namespace at org.netfrag.glib to |
57 |
|
* get a picture of how to implement own "actors". |
