Constructor Detail

ColumnStatistics

public ColumnStatistics(Long numberOfValues,
                        HiveBloomFilter bloomFilter)

Method Detail

hasNumberOfValues

public boolean hasNumberOfValues()

getNumberOfValues

public long getNumberOfValues()

hasMinAverageValueSizeInBytes

public boolean hasMinAverageValueSizeInBytes()

getMinAverageValueSizeInBytes

public long getMinAverageValueSizeInBytes()

The minimum average value sizes. The actual average value size is no less than the return value. It provides a lower bound of the size of data to be loaded

public BooleanStatistics getBooleanStatistics()

getDateStatistics

public DateStatistics getDateStatistics()

getDoubleStatistics

public DoubleStatistics getDoubleStatistics()

getIntegerStatistics

public IntegerStatistics getIntegerStatistics()

getStringStatistics

public StringStatistics getStringStatistics()

getDecimalStatistics

public DecimalStatistics getDecimalStatistics()

getBinaryStatistics

public BinaryStatistics getBinaryStatistics()

getBloomFilter

public HiveBloomFilter getBloomFilter()

withBloomFilter

public ColumnStatistics withBloomFilter(HiveBloomFilter bloomFilter)

getMembersSizeInBytes

protected final long getMembersSizeInBytes()

getRetainedSizeInBytes
