public BinaryStatistics()

Method Detail

updateStats

public void updateStats(Binary value)

Description copied from class: Statistics

updates statistics min and max using the passed value

Overrides:

updateStats in class Statistics<Binary>

Parameters:

value - value to use to update min and max

mergeStatisticsMinMax

public void mergeStatisticsMinMax(Statistics stats)

Description copied from class: Statistics

Abstract method to merge this statistics min and max with the values of the parameter object. Does not do any checks, only called internally.

Specified by:

mergeStatisticsMinMax in class Statistics<Binary>

Parameters:

stats - Statistics object to merge with

setMinMaxFromBytes

public void setMinMaxFromBytes(byte[] minBytes,
                      byte[] maxBytes)

Sets min and max values, re-uses the byte[] passed in. Any changes made to byte[] will be reflected in min and max values as well.

Specified by:

setMinMaxFromBytes in class Statistics<Binary>

Parameters:

minBytes - byte array to set the min value to

maxBytes - byte array to set the max value to

getMaxBytes

public byte[] getMaxBytes()

Description copied from class: Statistics

Abstract method to return the max value as a byte array

Specified by:

getMaxBytes in class Statistics<Binary>

Returns:

byte array corresponding to the max value

getMinBytes

public byte[] getMinBytes()

Description copied from class: Statistics

Abstract method to return the min value as a byte array

Specified by:

getMinBytes in class Statistics<Binary>

Returns:

byte array corresponding to the min value

isSmallerThan

public boolean isSmallerThan(long size)

Description copied from class: Statistics

Abstract method to return whether the min and max values fit in the given size.

Specified by:

isSmallerThan in class Statistics<Binary>

Parameters:

size - a size in bytes

Returns:

true iff the min and max values are less than size bytes

toString

public String toString()

Description copied from class: Statistics

toString() to display min, max, num_nulls in a string

Specified by:

toString in class Statistics<Binary>

initializeStats

@Deprecated
public void initializeStats(Binary min_value,
                              Binary max_value)
