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.
alias AssertHandler = void function(string file, ulong line, string msg) nothrow;
nothrow @nogc @property @trusted AssertHandler assertHandler();
nothrow @nogc @property @trusted void assertHandler(AssertHandler handler);
Gets/sets assert hander. null means the default handler is used.
deprecated nothrow @nogc @trusted void setAssertHandler(AssertHandler h);
Overrides the default assert hander with a user-supplied version. Deprecated. Please use assertHandler instead.
Parameters:
AssertHandler h The new assert handler. Set to null to use the default handler.
nothrow 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.
nothrow 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.
nothrow 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.
pure nothrow @safe 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:
nothrow @trusted void onFinalizeError(TypeInfo info, Throwable e, string file = __FILE__, size_t line = __LINE__);
A callback for finalize errors in D. A FinalizeError will be thrown.
Parameters:
TypeInfo info The TypeInfo instance for the object that failed finalization.
Throwable e The exception thrown during finalization.
string file The name of the file that signaled this error.
size_t line The line number on which this error occurred.
Throws:
pure nothrow @safe void onHiddenFuncError(Object o);
A callback for hidden function errors in D. A HiddenFuncError will be thrown.
pure nothrow @nogc @trusted void onOutOfMemoryError(void* pretend_sideffect = null);
A callback for out of memory errors in D. An OutOfMemoryError will be thrown.
pure nothrow @nogc @trusted void onInvalidMemoryOperationError(void* pretend_sideffect = null);
A callback for invalid memory operations in D. An InvalidMemoryOperationError will be thrown.
pure nothrow @safe 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:
pure @safe 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.
string file The name of the file that signaled this error.
size_t line The line number on which this error occurred.
