oldXORHashCode

@Deprecated
public int oldXORHashCode(Object[] rowData)
                               throws KettleValueException

Deprecated.

Calculate a hashCode of the content (not the index) of the data specified NOTE: This method uses a simple XOR of the individual hashCodes which can result in a lot of collisions for similar types of data (e.g. [A,B] == [B,A] and is not suitable for normal use. It is kept to provide backward compatibility with CombinationLookup.lookupValues()

Specified by:

oldXORHashCode in interface RowMetaInterface

Parameters:

rowData - The data to calculate a hashCode with

Returns:

the calculated hashCode

Throws:

KettleValueException - in case there is a data conversion error

hashCode

public int hashCode(Object[] rowData)
             throws KettleValueException

Calculates a simple hashCode of all the native data objects in the supplied row. This method will return a better distribution of values for rows of numbers or rows with the same values in different positions. NOTE: This method performs against the native values, not the values returned by ValueMeta. This means that if you have two rows with different primitive values ['2008-01-01:12:30'] and ['2008-01-01:00:00'] that use a format object to change the value (as Date yyyy-MM-dd), the hashCodes will be different resulting in the two rows not being considered equal via the hashCode even though compare() or equals() might consider them to be.

Specified by:

hashCode in interface RowMetaInterface

Parameters:

rowData - The data to calculate a hashCode with

Returns:

the calculated hashCode

Throws:

KettleValueException - in case there is a data conversion error

convertedValuesHashCode

public int convertedValuesHashCode(Object[] rowData)
                            throws KettleValueException

Calculates a hashcode of the converted value of all objects in the supplied row. This method returns distinct values for nulls of different data types and will return the same hashCode for different native values that have a ValueMeta converting them into the same value (e.g. ['2008-01-01:12:30'] and ['2008-01-01:00:00'] as Date yyyy-MM-dd)

Specified by:

convertedValuesHashCode in interface RowMetaInterface

Parameters:

rowData - The data to calculate a hashCode with

Returns:

the calculated hashCode

Throws:

KettleValueException - in case there is a data conversion error
