All Implemented Interfaces:
ComparisonStrategy
Direct Known Subclasses:

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

      Specified by:
      asText in class AbstractComparisonStrategy

    • areEqual

      public boolean areEqual(Object actual, Object other)
      Returns true if actual and other are equal based on Objects.deepEquals(Object, Object), false otherwise.
      Parameters:
      actual - the object to compare to other
      other - the object to compare to actual
      Returns:
      true if actual and other are equal based on Objects.deepEquals(Object, Object), false otherwise.

    • iterableContains

      public boolean iterableContains(Iterable<?> iterable, Object value)
      Returns true if given Iterable contains given value based on Objects.deepEquals(Object, Object), false otherwise.
      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 Objects.deepEquals(Object, Object), false otherwise.

    • iterableRemoves

      public void iterableRemoves(Iterable<?> iterable, Object value)
      Look for given value in given Iterable according to the implemented comparison strategy, if value is found it is removed from it.
      If given Iterable is null, does nothing.
      Parameters:
      iterable - the Iterable we want remove value from
      value - object to remove from given Iterable

    • iterablesRemoveFirst

      public void iterablesRemoveFirst(Iterable<?> iterable, Object value)
      Removes the first value in iterable that matches the value according to the implemented comparison strategy. 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 Iterable<?> duplicatesFrom(Iterable<?> iterable)
      Returns any duplicate elements from the given collection according to Objects.deepEquals(Object, Object) comparison strategy.
      Specified by:
      duplicatesFrom in interface ComparisonStrategy
      Overrides:
      duplicatesFrom in class AbstractComparisonStrategy
      Parameters:
      iterable - the given Iterable we want to extract duplicate elements.
      Returns:
      an Iterable containing the duplicate elements of the given one. If no duplicates are found, an empty Iterable is returned.
