=head1 NAME
HTML::Microformats::ObjectCache - cache for microformat objects
=head1 DESCRIPTION
Prevents microformats from being parsed twice within the same context.
This is not just for saving time. It also prevents the occasional infinite loop, and
makes sure identifiers are used consistently.
=head2 Constructor
=over
=item C<< $cache = HTML::Microformats::ObjectCache-E<gt>new >>
Creates a new, empty cache.
=back
=head2 Public Methods
=over
=item C<< $cache-E<gt>set($context, $package, $element, $object); >>
For a given context, package (e.g. 'HTML::Microformats::Format::hCard') and DOM
element node, stores an object in the cache.
=item C<< $object = $cache-E<gt>get($context, $package, $element); >>
For a given context, package (e.g. 'HTML::Microformats::Format::hCard') and DOM
element node, retrieves an object from the cache.
=item C<< @objects = $cache-E<gt>get_all($context, [$package]); >>
For a given context and package (e.g. 'HTML::Microformats::Format::hCard'), retrieves a
list of objects from within the cache.
