    - #### CombinableMatcher

          public CombinableMatcher(Matcher<? super T> matcher)

  - ### Method Detail

    - #### matchesSafely

          protected boolean matchesSafely(T item,
                                          Description mismatch)

      Description copied from class: `TypeSafeDiagnosingMatcher`
      Subclasses should implement this. The item will already have been checked for the specific type and will never be null.
      Specified by:
        `matchesSafely` in class `TypeSafeDiagnosingMatcher<T>`

    - #### describeTo

          public void describeTo(Description description)

      Description copied from interface: `SelfDescribing`
      Generates a description of the object. The description may be part of a a description of a larger object of which this is just a component, so it should be worded appropriately.
      Parameters:
        `description` - The description to be built or appended to.

    - #### and

          public CombinableMatcher<T> and(Matcher<? super T> other)

    - #### or

          public CombinableMatcher<T> or(Matcher<? super T> other)

    - #### both

          public static <LHS> CombinableMatcher.CombinableBothMatcher<LHS> both(Matcher<? super LHS> matcher)

      Creates a matcher that matches when both of the specified matchers match the examined object. For example:

          assertThat("fab", both(containsString("a")).and(containsString("b")))

    - #### either

          public static <LHS> CombinableMatcher.CombinableEitherMatcher<LHS> either(Matcher<? super LHS> matcher)

      Creates a matcher that matches when either of the specified matchers match the examined object. For example:

          assertThat("fan", either(containsString("a")).or(containsString("b")))
