| 5 | * are used throughout WarpIN for a more flexible error
|
|---|
| 6 | * handling. Some of the more complex constructors are
|
|---|
| 7 | * implemented in warpin.cpp.
|
|---|
| 8 | *
|
|---|
| 9 | * All exception classes are derived from BSExcptBase, so
|
|---|
| 10 | * you can always catch BSExcptBase too. main() in warpin.cpp
|
|---|
| 11 | * catches those exceptions, so if you don't, main() will.
