Method Detail

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 of SlotAcc.collect(DocSet, int, IntFunction) but it's also neccessary if this accumulator is used for sorting.

Specified by:

collect in class SlotAcc

Parameters:

doc - Single Segment docId (relative to the current LeafReaderContext to collect

slot - The slot number to collect this document in

slotContext - A callback that can be used for Accumulators that would like additional info about the current slot -- the IntFunction is only garunteed to be valid for the current slot, and the SlotAcc.SlotContext returned is only valid for the duration of the collect() 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 to org.apache.lucene.index.DocValuesIterator#advanceExact(int) returns whether or not given doc has value

Throws:

IOException
