ExceptionType

Files CCore/inc/gadget/ExceptionType.h CCore/src/gadget/ExceptionType.cpp

ExceptionType is an enum with two named values. It is used to handle an exceptional situation in CCore.

enum ExceptionType
 {
  NoException, // don't throw exception, just report a error
  Exception    // throw exception
 };

CatchType is an empty base class for exception classes.

struct CatchType 
 {
  CatchType() {}
 };

Handling exceptional situations

CCore uses the following pattern to handle exceptional situations. To throw an exception:

Printf(Exception,"message text",....);

This statement picks up an installed error report handler, prints the specified error message and then throws an exception of type CatchType.

To report a error without throwing an exception (i.e. inside a destructor):

Printf(NoException,"message text",....);

To catch exceptions use the following pattern:

try
  {
   ReportException report; // or some derived from the ReportException class

   {
    // do some job here
   }

   report.guard(); // throw an exception if there was Printf(NoException,....); above
  }
catch(CatchType)
  {
   // handle exception
  }
