Basically, it provides all of the necessary resolver methods but none of them do anything. This means that if you use this method things like C<< $interp->exec >> will simply not work at all. However, if you just want to make a component with an interpreter and execute that component it can be useful. For example: my $interp = HTML::Mason::Interp->new( resolver_class => 'HTML::Mason::Resolver::Null', data_dir => '/tmp' ); my $comp = $interp->make_component( comp_source => <<'EOF' ); % my $var = 'World'; Hello, <% $var %>! EOF my $buffer; my $request = $interp->make_request( out_method => \$buffer, comp => $comp ); $request->exec; print $buffer; =cut
