collect
public void collect(int doc, int slot, IntFunction<SlotAcc.SlotContext> slotContext) throws IOException
Description copied from class:SlotAcc
All subclasses must override this method to collect documents. This method is called by the default impl ofSlotAcc.collect(DocSet,int,IntFunction)
but it's also neccessary if this accumulator is used for sorting.- Specified by:
collect
in classSlotAcc
- Parameters:
doc
- Single Segment docId (relative to the currentLeafReaderContext
to collectslot
- The slot number to collect this document inslotContext
- A callback that can be used for Accumulators that would like additional info about the current slot -- theIntFunction
is only garunteed to be valid for the current slot, and theSlotAcc.SlotContext
returned is only valid for the duration of thecollect()
call.- Throws:
IOException
-
collectValues
protected abstract void collectValues(int doc, int slot) throws IOException
- Throws:
IOException

advanceExact
protected abstract boolean advanceExact(int doc) throws IOException
Wrapper toorg.apache.lucene.index.DocValuesIterator#advanceExact(int)
returns whether or not givendoc
