    • usingComparator

      public IntegerAssert usingComparator(Comparator<? super Integer> customComparator)
      Description copied from class: AbstractAssert
      Use given custom comparator instead of relying on actual type A equals method for incoming assertion checks.

      Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.

      Examples :

       // frodo and sam are instances of Character with Hobbit race (obviously :).
       // raceComparator implements Comparator<Character> 
       assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam); 
       
      Specified by:
      usingComparator in interface Assert<IntegerAssert,Integer>
      Overrides:
      usingComparator in class AbstractComparableAssert<IntegerAssert,Integer>
      Parameters:
      customComparator - the comparator to use for incoming assertion checks.
      Returns:
      this assertion object.
    • usingDefaultComparator

      public IntegerAssert usingDefaultComparator()
      Description copied from class: AbstractAssert
      Revert to standard comparison for incoming assertion checks.

      This method should be used to disable a custom comparison strategy set by calling Assert.usingComparator(Comparator).

      Specified by:
      usingDefaultComparator in interface Assert<IntegerAssert,Integer>
      Overrides:
      usingDefaultComparator in class AbstractComparableAssert<IntegerAssert,Integer>
      Returns:
      this assertion object.
