    • instance

      public static Comparables instance()
      Returns the singleton instance of this class based on StandardComparisonStrategy.
      Returns:
      the singleton instance of this class based on StandardComparisonStrategy.

    • getComparator

      public Comparator<?> getComparator()

    • assertEqual

      public <T> void assertEqual(AssertionInfo info, T actual, T expected)
      Asserts that two T instances are equal.
      Parameters:
      info - contains information about the assertion.
      actual - the actual value.
      expected - the expected value.
      Throws:
      AssertionError - if the actual value is null.
      AssertionError - if the actual value is not equal to the expected one. This method will throw a org.junit.ComparisonFailure instead if JUnit is in the classpath and the expected and actual values are not equal.

    • areEqual

      protected <T> boolean areEqual(T actual, T expected)

    • assertNotEqual

      public <T> void assertNotEqual(AssertionInfo info, T actual, T other)
      Asserts that two T instances are not equal.
      Parameters:
      info - contains information about the assertion.
      actual - the actual value.
      other - the value to compare the actual value to.
      Throws:
      AssertionError - if the actual value is null.
      AssertionError - if the actual value is equal to the other one.

    • assertEqualByComparison

      public <T extends Comparable<? super T>> void assertEqualByComparison(AssertionInfo info, T actual, T expected)
      Asserts that two Comparables are equal by invoking Comparable.compareTo(Object).
      Note that it does not rely on the custom comparisonStrategy if one has been set.
      Type Parameters:
      T - used to guarantee that two objects of the same type are being compared against each other.
      Parameters:
      info - contains information about the assertion.
      actual - the actual value.
      expected - the expected value.
      Throws:
      AssertionError - if the actual value is null.
      AssertionError - if the actual value is not equal to the expected one. This method will throw a org.junit.ComparisonFailure instead if JUnit is in the classpath and the expected and actual values are not equal.

    • assertNotEqualByComparison

      public <T extends Comparable<? super T>> void assertNotEqualByComparison(AssertionInfo info, T actual, T other)
      Asserts that two Comparables are not equal by invoking Comparable.compareTo(Object) .
      Note that it does not rely on the custom comparisonStrategy if one has been set.
      Type Parameters:
      T - used to guarantee that two objects of the same type are being compared against each other.
      Parameters:
      info - contains information about the assertion.
      actual - the actual value.
      other - the value to compare the actual value to.
      Throws:
      AssertionError - if the actual value is null.
      AssertionError - if the actual value is equal to the other one.

    • assertLessThan

      public <T extends Comparable<? super T>> void assertLessThan(AssertionInfo info, T actual, T other)
      Asserts that the actual value is less than the other one.
      Type Parameters:
      T - used to guarantee that two objects of the same type are being compared against each other.
      Parameters:
      info - contains information about the assertion.
      actual - the actual value.
      other - the value to compare the actual value to.
      Throws:
      AssertionError - if the actual value is null.
      AssertionError - if the actual value is not less than the other one: this assertion will fail if the actual value is equal to or greater than the other value.

    • assertLessThanOrEqualTo

      public <T extends Comparable<? super T>> void assertLessThanOrEqualTo(AssertionInfo info, T actual, T other)
      Asserts that the actual value is less than or equal to the other one.
