Method Detail

getN

public int getN()

getTestType

public final TestHandle getTestType()

maxUpdateDistance

public double maxUpdateDistance()

Returns:

Maximum distance for each update().

generate

public abstract double[] generate()

generateUpdates

public abstract double[][] generateUpdates(int n,
                                           double[] data,
                                           double[][] ups)

log

public void log(String str)

logWarning

public void logWarning(String str)

getTestStats

public TestStats getTestStats()

generateWindowQueries

public void generateWindowQueries(double[][] lower,
                                  double[][] upper)

generateQuery

public void generateQuery(double[] min,
                          double[] max,
                          double maxLen,
                          double avgQVol)

Generate query rectangle. This method should be overwritten by tests that provide non-standard queries.

Parameters:

min - output: query box minimum

max - output: query box maximum

maxLen - maximum allowed length for a query box in any dimension.

avgQVol - Average expected volume of a query box

generateQuery2

public void generateQuery2(double[] min,
                           double[] max,
                           double maxLen,
                           double avgQVol)

Generate query rectangle. THis is an improved version of the faulty generateQuery(double[], double[], double, double). This method should be overwritten by tests that provide non-standard queries.

Parameters:

min - output: query box minimum

max - output: query box maximum

maxLen - maximum allowed length for a query box in any dimension.

avgQVol - Average expected volume of a query box

generateQuery3

public void generateQuery3(double[] min,
                           double[] max,
                           double[] maxLen,
                           double[] maxLenProduct,
                           double avgQVol,
                           boolean ignoreChecks)

Generate query rectangle. This is an improved version of the faulty generateQuery2(double[], double[], double, double), which did not work well with natural datasets (not cuboid). This method should be overwritten by tests that provide non-standard queries.

Parameters:

min - output: query box minimum

max - output: query box maximum

maxLen - maximum allowed length for a query box in any dimension.

maxLenProduct - Increasing sum of products of lengths

avgQVol - Average expected volume of a query box

ignoreChecks - ignore checks?

min

public double min(int d)

max

public double max(int d)

len

public double len(int d)
