Class TestData

java.lang.Object
  org.apache.lucene.benchmark.stats.TestData

public class TestData
extends Object

This class holds together all parameters related to a test. Single test is performed several times, and all results are averaged.

Field Summary

static int[]	MAX_BUFFERED_DOCS_COUNTS
static int[]	MERGEFACTOR_COUNTS

Constructor Summary

TestData()

Method Summary

protected Object	clone()
static TestData[]	getAll(File[] sources, Analyzer[] analyzers) Prepare a list of benchmark data, using all possible combinations of benchmark parameters.
Analyzer	getAnalyzer()
Directory	getDirectory()
long	getHeap()
String	getId()
int	getMaxBufferedDocs()
int	getMergeFactor()
QueryData[]	getQueries()
Vector	getRunData()
File	getSource()
static TestData[]	getTestDataMinMaxMergeAndMaxBuffered(File[] sources, Analyzer[] analyzers) Similar to getAll(java.io.File[], org.apache.lucene.analysis.Analyzer[]) but only uses maxBufferedDocs of 10 and 100 and same for mergeFactor, thus reducing the number of permutations significantly.
boolean	isCompound()
boolean	isOptimize()
void	setAnalyzer(Analyzer analyzer)
void	setCompound(boolean compound)
void	setDirectory(Directory directory)
void	setHeap(long heap)
void	setId(String id)
void	setMaxBufferedDocs(int maxBufferedDocs)
void	setMergeFactor(int mergeFactor)
void	setOptimize(boolean optimize)
void	setQueries(QueryData[] queries)
void	setRunData(Vector runData)
void	setSource(File source)

Field Detail

MAX_BUFFERED_DOCS_COUNTS

public static int[] MAX_BUFFERED_DOCS_COUNTS

MERGEFACTOR_COUNTS

public static int[] MERGEFACTOR_COUNTS

Constructor Detail

TestData

public TestData()

Method Detail

showRunData

public String showRunData(String prefix)

getAll

public static TestData[] getAll(File[] sources,
                                Analyzer[] analyzers)

Prepare a list of benchmark data, using all possible combinations of benchmark parameters.

Parameters:

sources - list of directories containing different source document collections

analyzers - of analyzers to use.

getTestDataMinMaxMergeAndMaxBuffered

public static TestData[] getTestDataMinMaxMergeAndMaxBuffered(File[] sources,
                                                              Analyzer[] analyzers)

Similar to getAll(java.io.File[], org.apache.lucene.analysis.Analyzer[]) but only uses maxBufferedDocs of 10 and 100 and same for mergeFactor, thus reducing the number of permutations significantly. It also only uses compund file and optimize is always true.

Parameters:

sources -

analyzers -

Returns:

An Array of TestData
