Detailed Description

The exception classes used by Mantid.

All exceptions inherit from std:exception.

The exception tree is

• std::exception - Superclass of all standard exception, never thrown itself
  • std::bad_alloc - Thrown when new runs out of memory
  • std::bad_exception - Thrown if an exception is thrown which is not listed in a function's exception specification.
  • std::bad_cast - Thrown if you attempt an invalid dynamic_cast expression
  • std::bad_typeid - Thrown if you use a NULL pointer in a typeid expression
  • std::logic_error - Superclass for all logic errors, never thrown itself. Logic errors represent problems in the internal logic of a program; in theory, these are preventable, and even detectable before the program runs (e.g., violations of class invariants).
    • std::length_error - Thrown when an object is constructed that would exceed its maximum permitted size (e.g., a string instance).
    • std::domain_error - Thrown to report domain errors (domain in the mathematical sense).
    • std::out_of_range - Thrown if an argument has a value which is not within the expected range (e.g. boundary checks in string).
    • std::invalid_argument - Thrown to report invalid arguments to functions.
    • NotImplementedError - Thrown if accessing areas of code that are not implmented yet.
  • std::runtime_error - Superclass for all runtime errors, never thrown itself. Runtime errors represent problems outside the scope of a program; they cannot be easily predicted and can generally only be caught as the program executes.
    • std::range_error - Thrown to indicate range errors in internal computations.
    • std::overflow_error - Thrown to indicate arithmetic overflow.
    • std::underflow_error - Thrown to indicate arithmetic underflow.
    • FileError - Thrown to indicate errors with file operations.
      • ParseError - Thrown to indicate errors when parsing a file.
    • NotFoundError - Thrown to indicate that an item was not found in a collection.
    • ExistsError - Thrown to indicate that an item was is already found in a collection.
    • InstrumentDefinitionError - Thrown to indicate a problem with the instrument definition.
    • MisMatch - Error when two numbers should be identical (or close).
    • IndexError - Error when an incorrect index value is given.
    • NullPointerException - Thrown when a zero pointer is dereferenced.
    • InternetError - Thrown when an error occurs accessing an internet resource.
