Class VariableInt32BlockIndexOutput

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

Assembly: Lucene.Net.Codecs.dll
Syntax
public abstract class VariableInt32BlockIndexOutput : Int32IndexOutput
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
