Foswiki::Search::InfoCache
internal package
Foswiki::Search::InfoCache is a
Foswiki::ListIterator
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, $defaultWeb, \@topicList)
Initialise a new list of topics, allowing their data to be lazy loaded
if and when needed.
$defaultWeb is used to qualify topics that do not have a web
specifier - should expect it to be the same as BASEWEB in most cases.
Because this Iterator can be created and filled dynamically, once the Iterator hasNext() and next() methods are called, it is immutable.
ObjectMethod
sortResults($params)
the implementation of %SORT{"" limit="" order="" reverse="" date=""}%
it should be possible for the search engine to pre-sort, making this a nop, or to
delay evaluated, partially evaluated, or even delegated to the DB/SQL
can call repeatedly, the list will only be re-sorted if new elements are added.
filterByDate( $date )
Filter the list by date interval; see
Time Specifications.
This function adds a filter evaluator to the infocache that is evaluated
as you iterate through the collection
$infoCache->filterByDate( $date );

filters based on those options. \%options may include:
-
