Foswiki::Search::ResultSet
internal package
Foswiki::Search::ResultSet is a
Foswiki::Iterator
This class implements the
ResultSet API - its basically a Sorted Aggregate Iterator for foswiki 1.1
- NOTE: does not implement the unique function - by its nature, the data is unique, and it would be a non-trivial drain on memory in this context
(due to the partially completed
InfoCache removeal)
in future it will probably become more clever.
new(\@list)
Create a new iterator over the given list of iterators. The list is
not damaged in any way.
hasNext() -> $boolean
Returns false when the iterator is exhausted.
skip(count) -> $countremaining
skip X elements (returns 0 if successful, or number of elements remaining to skip if there are not enough elements to skip)
skip must set up next as though hasNext was called.
next() -> $data
Return the next entry in the list.
nextWeb() -> $data
switch tot he next Web (only works on partition==web, and if we've already started iterating.
sortResults
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
