.SH DESCRIPTION
.IX Header "DESCRIPTION"
This HTML::Mason::Resolver subclass is useful if you want to create
components via the \f(CW\*(C`HTML::Mason::Interp\->make_component\*(C'\fR method
and you never plan to interact with the filesystem.
.PP
Basically, it provides all of the necessary resolver methods but none
of them do anything.
.PP
This means that if you use this method things like \f(CW\*(C`$interp\->exec\*(C'\fR
will simply not work at all.
.PP
However, if you just want to make a component with an interpreter and
execute that component it can be useful.  For example:
.PP
.Vb 2
\&  my $interp = HTML::Mason::Interp\->new( resolver_class => \*(AqHTML::Mason::Resolver::Null\*(Aq,
\&                                         data_dir => \*(Aq/tmp\*(Aq );
\&
\&  my $comp = $interp\->make_component( comp_source => <<\*(AqEOF\*(Aq );
\&% my $var = \*(AqWorld\*(Aq;
\&Hello, <% $var %>!
\&EOF
\&
\&  my $buffer;
\&  my $request = $interp\->make_request( out_method => \e$buffer, comp => $comp );
\&  $request\->exec;
\&
\&  print $buffer;
