Constructor Detail

Initial

public Initial()

Constructor wit default sketch size and default mode

Initial

public Initial(String sketchSize)

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

Initial

public Initial(String sketchSize,
               String summaryMode)

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

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