/**

18
|
* Wrapps a result object so it can be used as method parameter and changed within the method.
|
|
19
|
* This is useful especially for simple data types like <code>Boolean</code> etc.<br>
|
|
20
|
* Example (usage):<br><code>
|
|
21
|
* public String myMethod(String oneParameter, ResultWrapper<Boolean> success){<br>
|
|
22
|
* __if (oneParameter.equals("foo")){<br>
|
|
23
|
* ____success = success.setValue(false);<br>
|
|
24
|
* ____return "Foo";<br>
|
|
25
|
* __}else{<br>
|
|
26
|
* ____//don't change success<br>
|
|
27
|
* ____return "All the best";<br>
|
|
28
|
* __}<br>
|
|
29
|
* }
|
|
30
|
* </code>
|
|
31
|
* Here a String is returned but the boolean value may also be changed and it's value is useable
|
|
32
|
* by the calling method
