    ComparisonStrategy
    public class StandardComparisonStrategy
extends AbstractComparisonStrategy
    Implements ComparisonStrategy contract with a comparison strategy based on Object.equals(Object) method, it is also based on Comparable.compareTo(Object) when Object are Comparable method.

        If given Iterable is null, return false.
        Parameters:
        iterable - the Iterable to search value in
        value - the object to look for in given Iterable
        Returns:
        true if given Iterable contains given value based on Object.equals(Object), false otherwise.

      • iterableRemoves

        public void iterableRemoves​(java.lang.Iterable<?> iterable,
                            java.lang.Object value)

        If given Iterable is null, does nothing.
        Parameters:
        iterable - the Iterable we want remove value from
        value - object to remove from given Iterable

      • duplicatesFrom

        public java.lang.Iterable<?> duplicatesFrom​(java.lang.Iterable<?> iterable)
