mitkReThrow

#define mitkReThrow

(

mitkexception

)

The rethrow macro is used to rethrow an existing exception. The rethrow information (file,line of code) is then additionally stored in the exception. To check if an exception was rethrown you can use the methods GetNumberOfRethrows() and GetRethrowData().

Example usage: try { //some code that throws an exception } catch(mitk::Exception e) { //here we want to rethrow the exception mitkReThrow(e) << "Message that will be appended to the exception (optional)"; }

mitkThrowException

#define mitkThrowException

(

classname

)

The specialized exception macro is used to throw exceptions in cases of specialized errors. This means the second parameter must be a class which inherits from mitk::Exception. An object of this exception is thrown when using the macro. Thus, more differentiated excaptions can be thrown, when needed.

Example usage: mitkSpecializedExceptionMacro(mitk::MySpecializedException) << "this is error info";
