alib::lox::textlogger::StandardConverter Class Reference

Description:

Implements the interface ObjectConverter. Class TextLogger creates an instance of this type in the moment no other (custom) type was set before the first log statement.

This implementation uses two specialisations of class Formatter to format the given logables to a textual representation. The formatters (and their sequence!) are:

1. FormatterPythonStyle
2. FormatterJavaStyle

This way, standard text logging supports format strings in Python style as well as in Java style.

Formatters

std::vector<Formatter*> alib::lox::textlogger::StandardConverter::Formatters

A list of formatters used to "convert" logables to strings. By default, each entry contains a concatenated pair of formatters of types FormatterPythonStyle and FormatterJavaStyle are added in the constructor of this class.

A vector of formatters is needed to support recursive log calls. If recursion occurs during logging (aka the conversion of a logable triggers another logging operation), necessary formatters are created on the fly, respectively re-used from previous recursions. Their settings are cloned to those of the main formatters using Formatter::CloneSettings.

To use different formatters, it is recommended to implement a different converter type, instead of "patching" the linked and recursive formatters found in this vector.

Method Details:

ConvertObjects()

void alib::lox::textlogger::StandardConverter::ConvertObjects ( AString & target, BoxesMA & logables )

overridevirtual

The conversion method. Passes target and logables to the Formatters.

Parameters

target	An AString that takes the result.
logables	The objects to convert.

Implements alib::lox::textlogger::ObjectConverter.

GetAutoSizes()

AutoSizes * alib::lox::textlogger::StandardConverter::GetAutoSizes ( )

overridevirtual

Checks if the first formatter in Formatters is of type FormatterPythonStyle. If so, its AutoSizes member is returned. If not, the method returns nullptr.

Returns

The auto sizes object of the main formatter.

ResetAutoSizes()

void alib::lox::textlogger::StandardConverter::ResetAutoSizes ( )

overridevirtual

Resets automatically widened tab stops and field widths of this converter.

Implements alib::lox::textlogger::ObjectConverter.

Definition at line 118 of file textlogger.cpp.

SetAutoSizes()

void alib::lox::textlogger::StandardConverter::SetAutoSizes ( AutoSizes * autoSizes )

overridevirtual

Checks if the first formatter in Formatters is of type FormatterPythonStyle. If so, its AutoSizes member is set to the given external instance. Otherwise the call is ignored.

Parameters

autoSizes

The instance to use.
