Interface PointWriter

All Superinterfaces:

AutoCloseable, Closeable

All Known Implementing Classes:

HeapPointWriter, OfflinePointWriter

public interface PointWriter
extends Closeable

Appends many points, and then at the end provides a PointReader to iterate those points. This abstracts away whether we write to disk, or use simple arrays in heap.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Method Summary

Modifier and Type	Method and Description
void	append(byte[] packedValue, int docID) Add a new point from the packed value and docId
void	append(PointValue pointValue) Add a new point from a PointValue
long	count() Return the number of points in this writer
void	destroy() Removes any temp files behind this writer
PointReader	getReader(long startPoint, long length) Returns a PointReader iterator to step through all previously added points
