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.

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.

Constructors

Name Description
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.

Fields

Name Description
m_output

Methods

Name Description
Add(Int32)

Called one value at a time. Return the number of buffered input values that have been written to out.

Dispose(Boolean)
GetIndex()
Write(Int32)
