Constructor Detail

LookupExtractionFunction

public LookupExtractionFunction(Lookup lookup,
                                Boolean retainMissingValue,
                                String replaceMissingValueWith,
                                Boolean injective,
                                Boolean optimize)

Constructor.

Parameters:

lookup - lookup property 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

LookupExtractionFunction

public LookupExtractionFunction(Lookup lookup)

Convenience Constructor,

defaults: retainMissingValue=false, replaceMissingValueWith=null, injective=false, optimize=true.

Parameters:

lookup - lookup property specified by the user
