|

3 |
|
---|
4 | @brief A base class taking care of padding, exit handler and error handlers
|
---|
5 |
|
---|
6 | This class first switches off padding for the DimServer and the DimClient
|
---|
7 | (dis and dic). Furthermore, it redirects both error handlers to the
|
---|
8 | DimErrorRedirecter. Redirect the exit handler.
|
---|
9 |
|
---|
10 | Only one instance of this class is allowed, since all Dim handlers are
|
---|
11 | global.
|
---|
12 |
|
---|
13 | In the destructor of the class the handlers are correctly restored.
|
---|
14 | The padding setup is kept.
|
---|
15 |
|
---|
16 | For FACT++ all Dim data is transmitted without padding!
|
---|
17 |
|
---|
18 | To catch the error messages overwrite the errorHandler. The errorHandler
|
---|
19 | of the DimErrorRedirecter redirects the error messages to the logging
|
---|
20 | stream given in the constructor.
|
---|
21 |
|
---|
22 | To catch the exit requests overwrite the exitHandler.
