Description:

Automatically detected field width and tab-stop positions for the meta-information part as well as the log message part, collected during the run of a software. This struct is used to define an external configuration variable named ALOX/LOGGERNAME/AUTO_SIZES.

This variable can be accessed programatically either with method TextLogger::GetAutoSizes or by accessing the variable's value through the configuration object found in camp singleton alib::ALOX.

For almost all use cases, field Main will work as expected, because the meta-information of log lines usually do not change. In other words, if they get changed, it is a good idea to invoke AutoSizes::Reset on that field.

Field LogMessage with built-in text loggers, is passed to field FormatterPythonStyle::Sizes and thus is used to organize tab-stops and field widths of the log messages itself.
The field may be reset manually after (or before) a coherent set of log messages have been (respectively are to be) written. Such "coherent set" is for example the output of tabular data. If this is not done, a next table containing different data, would not be printed with correct field sizes in case the automatic tab-stops.

Also, it might be reasonable to invoke Consolidate one both objects from time to time, or in certain situations.
