Type Parameters:

T - the record type

All Implemented Interfaces:

FuzzyValueMatcher<T>

public class NaiveFuzzyValueMatcher<T>
extends Object
implements FuzzyValueMatcher<T>

removeMatchingValues

public void removeMatchingValues(TypeConfig<T> typeConfig,
                        Collection<T> expectedValues,
                        Collection<T> actualValues)

Description copied from interface: FuzzyValueMatcher

Removes all pairs of matching items from the two collections. The cardinality of both collections is guaranteed to be the same on input and does not have to be equal on output.
Since both collections have the bag semantic, some values may appear multiple times. The algorithm should remove only one value per matching pair unless otherwise documented.

Specified by:

removeMatchingValues in interface FuzzyValueMatcher<T>

expectedValues - a bag of expected values

actualValues - a bag of actual values
