Class VariableInt32BlockIndexOutput

Abstract base class that writes variable-size blocks of ints to an Lucene.Net.Store.IndexOutput. While this is a simple approach, a more performant approach would directly create an impl of Int32IndexOutput inside Lucene.Net.Store.Directory. Wrapping a generic Lucene.Net.Store.IndexOutput will likely cost performance.

NOTE: This was VariableIntBlockIndexOutput in Lucene

Note

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

Syntax
public abstract class VariableInt32BlockIndexOutput : Int32IndexOutput, IDisposable
Remarks

Naive int block API that writes vInts. This is expected to give poor performance; it's really only for testing the pluggability. One should typically use pfor instead.

VariableInt32BlockIndexOutput(IndexOutput, Int32)

NOTE: maxBlockSize must be the maximum block size plus the max non-causal lookahead of your codec. EG Simple9 requires lookahead=1 because on seeing the Nth value it knows it must now encode the N-1 values before it.

Declaration
protected VariableInt32BlockIndexOutput(IndexOutput output, int maxBlockSize)
Parameters
