Method Details

similarityThreshold

public double similarityThreshold()

Specified by:

similarityThreshold in interface MultiMatcher<E>

singletonPrecedenceThreshold

public double singletonPrecedenceThreshold()

Description copied from interface: MultiMatcher

This is a measure of how "eager" the algorithm is to find as many matches as possible. The lower this threshold is, the more "single potential match" items will be preferred over actually better matching pairs just to not leave them unmatched. To deactivate this special casing, set the threshold to 1.0, meaning only items that fit perfectly anyway take precedence over others.

Specified by:

singletonPrecedenceThreshold in interface MultiMatcher<E>

Returns:

the singleton precedence threshold
