[Log4cplus-devel] log4cplus question

[Semyon K. <skl...@in...>]

Hi,

 

I have a some difficulties in creating of custom layout.

 

I have derived base log4cplus::Layout class:

 

class LogLayout : public Layout

{

public:

      LogLayout(void);

      ~LogLayout(void);

 

      virtual void formatAndAppend(log4cplus::tostream& output, const
log4cplus::spi::InternalLoggingEvent& event);

};

 

The problem is that in formatAndAppend function parameters there is an
InternalLoggingEvent object only and I have no way to put my parameters
there.

 

The only way I found is to format the message before I send it to
logger:

 

void LogLayout::formatAndAppend(log4cplus::tostream& output,

const log4cplus::spi::InternalLoggingEvent& event)

{

      output << event.getMessage();

}

 

 

Could you please explain me what  is the right way to create a custom
layout?

 

Thank you,

Semyon
