Field Summary

int[]	docToEntry Maps each document to the ordinal for its value.
long[]	offsets File-offset for each document; will be null if it's not needed (eg fixed-size values).
int	sizePerValues How many bytes each value occupies, or -1 if it varies.

Constructor Summary

SortedBytesMergeUtils.MergeContext(Comparator<BytesRef> comp, int mergeDocCount, int size, DocValues.Type type)
Sole constructor.

Method Summary

int	getMergeDocCount() Returns number of documents merged.
