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. Deprecated. This feature is not longer part of the language.

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:

RangeError.

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:

FinalizeError.

deprecated pure nothrow @safe void onHiddenFuncError(Object o);

A callback for hidden function errors in D. A HiddenFuncError will be thrown. Deprecated. This feature is not longer part of the language.

Throws:

HiddenFuncError.

pure nothrow @nogc @trusted void onOutOfMemoryError(void* pretend_sideffect = null);

A callback for out of memory errors in D. An OutOfMemoryError will be thrown.

Throws:

OutOfMemoryError.

pure nothrow @nogc @trusted void onInvalidMemoryOperationError(void* pretend_sideffect = null);

A callback for invalid memory operations in D. An InvalidMemoryOperationError will be thrown.

Throws:

InvalidMemoryOperationError.

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:

SwitchError.

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.

Throws:

UnicodeException.
