Member Function Documentation

interleave()

CirrusSearch\Search\TeamDraftInterleaver::interleave	(	CirrusSearchResultSet	$a,
		CirrusSearchResultSet	$b,
			$limit )

Parameters

CirrusSearchResultSet	$a	Results for team A
CirrusSearchResultSet	$b	Results for team B
int	$limit	Maximum number of results to return

Returns

CirrusSearchResultSet

interleaveResults()

static CirrusSearch\Search\TeamDraftInterleaver::interleaveResults ( $a, $b, $limit )

static

Interleave two arrays using team draft interleaving.

Only public for unit tests. The id's used as keys in $a and $b must represent the same thing, to prevent duplicates in the returned results.

Parameters

mixed[]	$a	Map from id to anything in preferred order for team A
mixed[]	$b	Map from id to anything in preferred order for team B
int	$limit	Maximum number of results to interleave

Returns

mixed[] Four item array. first item being the values from $a and $b in the interleaved ordering, second the ids belonging to team A, third the ids belonging to team B, and finally the offset for the next page in $a.
