All Implemented Interfaces:

Closeable

public abstract class FixedIntBlockIndexOutput
extends IntIndexOutput

Abstract base class that writes fixed-size blocks of ints to an IndexOutput. While this is a simple approach, a more performant approach would directly create an impl of IntIndexOutput inside Directory. Wrapping a generic IndexInput will likely cost performance.

WARNING: This API is experimental and might change in incompatible ways in the next release.

Field Summary

Method Summary
