|
* Abstract class to handle review in the system |
|
18
|
|
|
* Each Study-Visit should extend this abstract class and redifine the two abstract methods |
|
19
|
|
|
* - saveSpecificForm : Which recieve the raw form and should write data to the specific table of database |
|
20
|
|
|
* - setVisitValidation : Which should define the rules to change status of review's visit (ex : Wait Adjudication or Done) |
|
21
|
|
|
* |
|
22
|
|
|
* These two methodes will be launched for each new review recieved by the system |
|
23
|
|
|
* |
|
24
|
|
|
* The makeReviewUnavailable() can be overrided to let the visit available for review even if Review status "Done" is reached |
|
25
|
|
|
* (by default it will no longer accept new review after reaching this status) |

Adding explicit visibility (
private,protected, orpublic) is generally recommend to communicate to other developers how, and from where this method is intended to be used.
