inObject - the SystemObject to match

searchOptions - the options used for the search. From this it is possible to tell whether it is a weighted search or a normal match.

previousBlockIDs - the list of block IDs that have already been used in previous match passes for matching this SystemObject

remainingBlockIDs - a list of remaining block IDs that have not yet been used in previous match passes for matching this SystemObject

Returns:

the blockID to use for the next match pass

NoBlockApplicableException - if no block IDs remain that are applicable This signals the MatchEngineController that matching for this SystemObject is complete
