Constructor Detail

Initial

public Initial()

Constructor for the initial pass of an Algebraic function using default parameters.

Initial

public Initial(String numValues)

Constructor for the initial pass of an Algebraic function. This will be passed the same constructor arguments as the original UDF.

Parameters:

numValues - String representation of number of values per key

Initial

public Initial(String sketchSize,
               String numValues)

Constructor for the initial pass of an Algebraic function. This will be passed the same constructor arguments as the original UDF.

Parameters:

sketchSize - String representation of sketch size

numValues - String representation of number of values per key
