PointWriter

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable

All Known Implementing Classes:

HeapPointWriter, OfflinePointWriter
```
public interface PointWriter
extends java.io.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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	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
