getLongestMatch

public X getLongestMatch(X item,
                         List<X> items,
                         PredictiveInputModel<X> pim)

longest match

getSharedMaskExtension

public String getSharedMaskExtension(List<X> items,
                                     PredictiveInputModel<X> pim)

Description copied from interface: PredictiveInputModel.MatchingStrategy

Returns the shared mask extension for the list of items.

Specified by:

getSharedMaskExtension in interface PredictiveInputModel.MatchingStrategy<X extends Comparable<? super X>>

Parameters:

items - items for which the mask extension should be generated

pim - predictive input model

Returns:

the shared mask extension

getExtendedSharedMask

public String getExtendedSharedMask(List<X> items,
                                    PredictiveInputModel<X> pim)
