.IX Header "DESCRIPTION"
This class is used for internal testing of \f(CW\*(C`Log::Log4perl\*(C'\fR. It
is a \f(CW\*(C`Log::Dispatch\*(C'\fR\-style appender, which writes to a buffer 
in memory, from where actual results can be easily retrieved later
to compare with expeced results.
.PP
Every buffer created is stored in an internal global array, and can
later be referenced by name:
.PP
.Vb 1
\&    my $app = Log::Log4perl::Appender::TestBuffer->by_name("mybuffer");
.Ve
.PP
retrieves the appender object of a previously created buffer \*(L"mybuffer\*(R".
To reset this global array and have it forget all of the previously 
created testbuffer appenders (external references to those appenders
nonwithstanding), use
.PP
.Vb 1
\&    Log::Log4perl::Appender::TestBuffer->reset();
