Constructor Detail

RegisteredLookupExtractionFunction

public RegisteredLookupExtractionFunction(String lookup,
                                          Boolean retainMissingValue,
                                          String replaceMissingValueWith,
                                          Boolean injective,
                                          Boolean optimize)

Constructor.

Parameters:

lookup - lookup's name specified by the user

retainMissingValue - when true: returns original dimension value if mapping is not found, also note that replaceMissingValueWith must be null or empty string, when false: missing values are treated as missing

replaceMissingValueWith - replaces dimension values not found in mapping with this value and retainMissingValue must be false if this value is not null or is not empty string

injective - set to true to apply some optimization given that mapping is one-to-one, may cause undefined behavior if retainMissingValue is false and injective is true

optimize - set to false to turn off rewriting extraction filter as selector filters
