|

| 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.
