◆ SystemExceptions

enum class SystemExceptions

strong

Denotes exceptions thrown by classes of namespace alib::lang::system.

Enumerator
OK	Everything is fine.

Definition at line 282 of file systemerrors.hpp.

Function Details:

◆ CreateSystemException()

ALIB_API Exception CreateSystemException	(	const NCString &	file,
		int	line,
		const NCString &	func,
		int	errNo )

Namespace function that creates an according Exception to a corresponding system error number.

The small challenge here is that arbitrary error numbers (of unknown) type might occur, that do not have a corresponding enum record. SystemErrors::UNKNOWN is thrown and only the number is displayed in the description text.

Parameters

file	File name of the place of exception creation.
line	Line number of the place of exception creation.
func	Function/method name of the place of exception creation.
errNo	The system's error number.

Returns: An exception object.

Definition at line 1100 of file basecamp.cpp.

Here is the call graph for this function:

◆ FFormat_DateTime()

ALIB_API void FFormat_DateTime	(	const Box &	self,
		const String &	formatSpec,
		NumberFormat &	nf,
		AString &	target )

Implementation of FFormat for boxable type DateTime .
Writes the content of box (which is of type DateTime) to the given AString object target using a local instance of class CalendarDateTime and its method CalendarDateTime::Format .

If parameter formatSpec is empty, a default format string defined by string resource of key "DFMT" is used.

Note: This interface implementation is only available if modules ALib BaseCamp and ALib Time are included in the library distribution.
