class RangeError: object.Error;
  Thrown on a range error.

class AssertError: object.Error;
  Thrown on an assert error.

class FinalizeError: object.Error;
  Thrown on finalize error.

class HiddenFuncError: object.Error;
  Thrown on hidden function error.

class OutOfMemoryError: object.Error;
  Thrown on an out of memory error.

class InvalidMemoryOperationError: object.Error;
  Thrown on an invalid memory operation.

  An invalid memory operation error occurs in circumstances when the garbage collector has detected an operation it cannot reliably handle. The default D GC is not re-entrant, so this can happen due to allocations done from within finalizers called during a garbage collection cycle.

class SwitchError: object.Error;
  Thrown on a switch error.

class UnicodeException: object.Exception;
  Thrown on a unicode conversion error.

void setAssertHandler(errorHandlerType h);
  Overrides the default assert hander with a user-supplied version.

  Parameters:

  errorHandlerType h | The new assert handler. Set to null to use the default handler.

void onAssertError(string file = __FILE__, size_t line = __LINE__);
  A callback for assert errors in D. The user-supplied assert handler will be called if one has been supplied, otherwise an AssertError will be thrown.

  Parameters:

  string file | The name of the file that signaled this error.
  size_t line | The line number on which this error occurred.

void onAssertErrorMsg(string file, size_t line, string msg);
  A callback for assert errors in D. The user-supplied assert handler will be called if one has been supplied, otherwise an AssertError will be thrown.

  Parameters:

  string file | The name of the file that signaled this error.
  size_t line | The line number on which this error occurred.
  string msg | An error message supplied by the user.

void onUnittestErrorMsg(string file, size_t line, string msg);
  A callback for unittest errors in D. The user-supplied unittest handler will be called if one has been supplied, otherwise the error will be written to stderr.

  Parameters:

  string file | The name of the file that signaled this error.
  size_t line | The line number on which this error occurred.
  string msg | An error message supplied by the user.

void onRangeError(string file = __FILE__, size_t line = __LINE__);
  A callback for array bounds errors in D. A RangeError will be thrown.

  Parameters:

  string file | The name of the file that signaled this error.
  size_t line | The line number on which this error occurred.

  Throws:
  RangeError.

void onFinalizeError(ClassInfo info, Exception e, string file = __FILE__, size_t line = __LINE__);
  A callback for finalize errors in D. A FinalizeError will be thrown.

  Parameters:

  Exception e | The exception thrown during finalization.

  Throws:
  FinalizeError.

void onHiddenFuncError(Object o);
  A callback for hidden function errors in D. A HiddenFuncError will be thrown.

  Throws:
  HiddenFuncError.

void onOutOfMemoryError();
  A callback for out of memory errors in D. An OutOfMemoryError will be thrown.

  Throws:
  OutOfMemoryError.

void onInvalidMemoryOperationError();
  A callback for invalid memory operations in D. An InvalidMemoryOperationError will be thrown.

  Throws:
  InvalidMemoryOperationError.

void onSwitchError(string file = __FILE__, size_t line = __LINE__);
  A callback for switch errors in D. A SwitchError will be thrown.

  Parameters:

  string file | The name of the file that signaled this error.
  size_t line | The line number on which this error occurred.

  Throws:
  SwitchError.

void onUnicodeError(string msg, size_t idx, string file = __FILE__, size_t line = __LINE__);
  A callback for unicode errors in D. A UnicodeException will be thrown.

  Parameters:

  string msg | Information about the error.
  size_t idx | String index where this error was detected.

  Throws:
  UnicodeException.
