Constructor Detail

IntermediateFinal

public IntermediateFinal()

Constructor for the intermediate and final passes of an Algebraic function. Using default parameters.

IntermediateFinal

public IntermediateFinal(String numValues)

Constructor for the intermediate and final passes of an Algebraic function. This will be passed the same constructor arguments as the original UDF.

Parameters:

numValues - Number of double values to keep for each key

IntermediateFinal

public IntermediateFinal(String sketchSize,
                         String numValues)

Constructor for the intermediate and final passes of an Algebraic function. This will be passed the same constructor arguments as the original UDF.

Parameters:

sketchSize - String representation of sketch size

numValues - Number of double values to keep for each key

IntermediateFinal

public IntermediateFinal(String sketchSize,
                         String samplingProbability,
                         String numValues)

Constructor for the intermediate and final passes of an Algebraic function. This will be passed the same constructor arguments as the original UDF.

Parameters:

sketchSize - String representation of sketch size

samplingProbability - probability from 0 to 1

numValues - Number of double values to keep for each key
