 Page hashChannelsPage,
 Page allChannelsPage,
 long rawHash)

getJoinPosition

default void getJoinPosition(int[] positions,
 Page hashChannelsPage,
 Page allChannelsPage,
 long[] result)

The `result` array is global to the entire processed page, while the `positions` array may hold any number of selected positions from this page

getJoinPosition

long getJoinPosition(int position,
 Page hashChannelsPage,
 Page allChannelsPage)

getNextJoinPosition

long getNextJoinPosition(long currentJoinPosition,
 int probePosition,
 Page allProbeChannelsPage)
