LogString toAppendTo,
log4cxx::helpers::Pool p 
) const [pure virtual]

void format ( const log4cxx::helpers::ObjectPtr obj,
LogString toAppendTo,
log4cxx::helpers::Pool p 
) const
virtual bool handlesThrowable ( ) const [virtual]

Normally pattern converters are not meant to handle Exceptions although few pattern converters might.

By examining the return values for this method, the containing layout will determine whether it handles throwables or not.

Returns:
true if this PatternConverter handles throwables

Reimplemented in ThrowableInformationPatternConverter.
