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:
