Detailed Description

Standard exception handling object.

ExceptionObject provides standard methods for throwing and managing exceptions in itk. Specific exceptions should be derived from this class. Note that this class is derived from std::exception, so an application can catch ITK exceptions as std::exception if desired.

ExceptionObject maintains two types of information: a location and description (both of which are strings). The location is the point in the code where the exception was thrown; the description is an error message that describes the exception. The ExceptionObject can be thrown explicitly in code, or more conveniently, the itkExceptionMacro (found in Common/itkMacro.h) can be used.

Examples:

Examples/Filtering/DiffusionTensor3DReconstructionImageFilter.cxx, ImageLinearIteratorWithIndex.cxx, ImageRegionIterator.cxx, and ImageRegionIteratorWithIndex.cxx.

Constructor & Destructor Documentation

itk::ExceptionObject::ExceptionObject

(

)

Various types of constructors. Note that these functions will be called when children are instantiated. The default constructor and the copy constructor of ExceptionObject never throw an exception.

Assignment operator.

virtual bool itk::ExceptionObject::operator== ( const ExceptionObject &  orig )

virtual

Equivalence operator.

virtual void itk::ExceptionObject::Print ( std::ostream &  os ) const

virtual

Print exception information. This method can be overridden by specific exception subtypes. The default is to print out the location where the exception was first thrown and any description provided by the ``thrower''.

virtual void itk::ExceptionObject::SetDescription ( const std::string &  s )

virtual

Referenced by itk::ProgressReporter::CompletedPixel(), itk::ConstNeighborhoodIterator< TSparseImageType >::IsAtEnd(), itk::ProcessAborted::ProcessAborted(), and itk::RegularStepGradientDescentBaseOptimizer::StepAlongGradient().

virtual void itk::ExceptionObject::SetDescription ( const char *  s )

virtual

virtual void itk::ExceptionObject::SetLocation ( const std::string &  s )

virtual

Methods to get and set the Location and Description fields. The Set methods are overloaded to support both std::string and const char array types. Get methods return const char arrays.

Referenced by itk::RegularStepGradientDescentBaseOptimizer::StepAlongGradient().

virtual void itk::ExceptionObject::SetLocation ( const char *  s )
