Detailed Description

Represents an exception type in the exception handling system

The types of the exceptions a program will use are defined in source code files through the macro E4C_DEFINE_EXCEPTION. In addition, they are declared in header files through the macro E4C_DECLARE_EXCEPTION.

When defining types of exceptions, they are given a name, a default message and a supertype to organize them into a pseudo-hierarchy:

E4C_DEFINE_EXCEPTION(SimpleException, "Simple exception", RuntimeException);

Exceptions are defined as global objects. There is a set of predefined exceptions built into the framework; #RuntimeException is the root of the exceptions pseudo-hierarchy:

#RuntimeException
- #NotEnoughMemoryException
- #AssertionException
- #IllegalArgumentException
- #InputOutputException
- #SignalException
  - #SignalAlarmException
  - #SignalChildException
  - #SignalTrapException
  - #ErrorSignalException
    - #IllegalInstructionException
    - #ArithmeticException
    - #BrokenPipeException
    - #BadPointerException
      - #NullPointerException
  - #ControlSignalException
    - #StopException
    - #KillException
    - #HangUpException
    - #TerminationException
    - #AbortException
    - #CPUTimeException
    - #UserControlSignalException
      - #UserQuitException
      - #UserInterruptionException
      - #UserBreakException
  - #ProgramSignalException
    - #ProgramSignal1Exception
    - #ProgramSignal2Exception
