Class Element<T>

  • All Implemented Interfaces:
    Matchable
    public class Element<T>
extends Object
implements Matchable

    This class represent the string "value" against which match are run.

    Configurable attributes

    • type - The ElementType for the value. This determines the functions applied at different steps of the match
    • weight - Used in scoring function to increase the Document score for an Element. Default is 1.0 for all elements
    • threshold - Value above which elements are considered a match, default 0.3
    • neighborhoodRange - Relevant for NEAREST_NEIGHBORS MatchType. Defines how close should the value be, to be considered a match (default 0.9)
    • preProcessFunction - Function to pre-process the value. If this is not set, the function defined in ElementType is used
    • tokenizerFunction - Function to break values into tokens. If this is not set, the function defined in ElementType is used
    • matchType - MatchType used. If this is not set, the type defined in ElementType is used

      • getScore

        public double getScore​(Integer matchingCount,
                       Element other)

      • getChildCount

        public long getChildCount​(Matchable other)
        This gets the Max number of tokens present between matching Elements. For Elements that do not have a balanced set of tokens, it can push the score down.
