/**
This is a very simple filter based on string matching.

<p>The filter admits two options <b>StringToMatch</b> and
<b>AcceptOnMatch</b>. If there is a match between the value of the
StringToMatch option and the message of the {@link spi::LoggingEvent
LoggingEvent}, then the #decide method returns
{@link log4cxx::spi::Filter#ACCEPT ACCEPT} if the <b>AcceptOnMatch</b> option
value is true, if it is false then {@link log4cxx::spi::Filter#DENY DENY} is
returned. If there is no match, {@link log4cxx::spi::Filter#NEUTRAL NEUTRAL}
is returned.

<p>See configuration files <a
