The functions in this section work with and manipulate the active log target.

There are two functions which must be implemented by any derived class to
actually process the log messages: \helpref{DoLog}{wxlogdolog} and

active log target if there is any, does nothing otherwise.

+\membersection{wxLog::SetRepetitionCounting}\label{wxlogsetrepetitioncounting}
+
+\func{static void}{SetRepetitionCounting}{\param{bool }{ repetCounting = true}}

+Enables logging mode in which a log message is logged once, and in case exactly

+repetitions is logged.

+\func{static void}{SetTimestamp}{\param{const wxString\&}{ format}}
Sets the timestamp format prepended by the default log targets to all
messages. The string may contain any normal characters as well as \%
prefixed format specificators, see {\it strftime()} manual for details.

Returns the current trace mask, see \helpref{Customization}{wxlogcustomization} section

-\section{\class{wxLogPassThrough}}\label{wxlogpassthrough}
+\section{\class{wxLogInterposer}}\label{wxloginterposer}
A special version of \helpref{wxLogChain}{wxlogchain} which uses itself as the
-new log target. Maybe more clearly, it means that this is a log target which
-forwards the log messages to the previously installed one in addition to
+new log target. It forwards log messages to the previously installed one in addition to
processing them itself.
Unlike \helpref{wxLogChain}{wxlogchain} which is usually used directly as is,
this class must be derived from to implement \helpref{DoLog}{wxlogdolog}
and/or \helpref{DoLogString}{wxlogdologstring} methods.
+wxLogInterposer destroys the previous log target in its destructor. If you
+don't want this to happen, use wxLogInterposerTemp instead.
