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.
ClassMethod
new($session)
ObjectMethod
finish()
Break circular references.
Note to developers; please undef
all fields in the object explicitly,
whether they are references or not. That way this method is "golden
documentation" of the live fields in the object.
ObjectMethod
hasCached($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
