Class VariableIntBlockIndexInput

java.lang.Object

org.apache.lucene.codecs.sep.IntIndexInput

org.apache.lucene.codecs.intblock.VariableIntBlockIndexInput

All Implemented Interfaces:

Closeable

public abstract class VariableIntBlockIndexInput
extends IntIndexInput

Abstract base class that reads variable-size blocks of ints from an IndexInput. While this is a simple approach, a more performant approach would directly create an impl of IntIndexInput 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.
