* Many of the methods on this class are static and serve one of two purposes.
|
|
|
36 |
* 1. encapsulate functionality in an effort to ensure minimal changes between the different

|
37 |
* methods of interaction. Specifically browser, AJAX and webservice.
|
|
|
38 |
* 2. abstract logic for acquiring actions away from output so that renderers may use them without
|
|
|
39 |
* having to include any logic or capability checks.
