Constructor Detail

IntermediateFinal

public IntermediateFinal()

Constructor for the intermediate and final passes of an Algebraic function. Default sketch size and default mode.

IntermediateFinal

public IntermediateFinal(String sketchSize)

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

IntermediateFinal

public IntermediateFinal(String sketchSize,
                         String summaryMode)

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

summaryMode - String representation of mode (sum, min or max)
