internal package Foswiki::MetaCache
A cache of Meta objects - initially used to speed up searching and sorting, but by foswiki 2.0 hopefully this
will be used for all readonly accesses to the store.
Replaces the mishmash of the Search InfoCache
Support package; cache of topic info.
When information about search hits is
compiled for output, this cache is used to avoid recovering the same info
about the same topic more than once.
Break circular references.
Note to developers; please undef all
fields in the object explicitly,
whether they are references or not. That way this method is "golden
documentation" of the live fields in the object.
ObjectMethod hasCached($webtopic) → boolean
returns true if the topic is already int he cache.
get a requested meta object - web or topic typically, might work for attachments too
optionally the $meta parameter can be used to add that to the cache - useful if you've already loaded and parsed the topic.
TODO: the non-meta SEARCH render specific bits need to be moved elsewhere
and then, the MetaCache
can only return Meta objects that actually exist
