|
|
|
* TException class |
|
18
|
|
|
* |
|
19
|
|
|
* TException is the base class for all PRADO exceptions. |
|
20
|
|
|
* |
|
21
|
|
|
* TException provides the functionality of translating an error code |
|
22
|
|
|
* into a descriptive error message in a language that is preferred |
|
23
|
|
|
* by user browser. Additional parameters may be passed together with |
|
24
|
|
|
* the error code so that the translated message contains more detailed |
|
25
|
|
|
* information. |
|
26
|
|
|
* |
|
27
|
|
|
* By default, TException looks for a message file by calling |
|
28
|
|
|
* {@link getErrorMessageFile()} method, which uses the "message-xx.txt" |
|
29
|
|
|
* file located under "Prado\Exceptions" folder, where "xx" is the |
|
30
|
|
|
* code of the user preferred language. If such a file is not found, |
|
31
|
|
|
* "message.txt" will be used instead. |
