  - ### Method Detail

    - #### matchesSafely

          protected boolean matchesSafely(java.lang.Iterable<? super T> collection,
                                          Description mismatchDescription)

      Deprecated.
      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<java.lang.Iterable<? super T>>`

    - #### describeTo

          public void describeTo(Description description)

      Deprecated.
      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.

    - #### hasItem

          public static <T> Matcher<java.lang.Iterable<? super T>> hasItem(Matcher<? super T> itemMatcher)

      Deprecated. As of version 2.1, use `IsIterableContaining.hasItem(Matcher)`.
      Creates a matcher for `Iterable`s that only matches when a single pass over the examined `Iterable` yields at least one item that is matched by the specified `itemMatcher`. Whilst matching, the traversal of the examined `Iterable` will stop as soon as a matching item is found. For example:

          assertThat(Arrays.asList("foo", "bar"), hasItem(startsWith("ba")))

      Parameters:
        `itemMatcher` - the matcher to apply to items provided by the examined `Iterable`

    - #### hasItem

          public static <T> Matcher<java.lang.Iterable<? super T>> hasItem(T item)

      Deprecated. As of version 2.1, use `IsIterableContaining.hasItem(Object)`.
      Creates a matcher for `Iterable`s that only matches when a single pass over the examined `Iterable` yields at least one item that is equal to the specified `item`. Whilst matching, the traversal of the examined `Iterable` will stop as soon as a matching item is found. For example:

          assertThat(Arrays.asList("foo", "bar"), hasItem("bar"))

      Parameters:
        `item` - the item to compare against the items provided by the examined `Iterable`

    - #### hasItems

          @SafeVarargs
          public static <T> Matcher<java.lang.Iterable<T>> hasItems(Matcher<? super T>... itemMatchers)

      Deprecated. As of version 2.1, use `IsIterableContaining.hasItems(Matcher[])`}.
      Creates a matcher for `Iterable`s that matches when consecutive passes over the examined `Iterable` yield at least one item that is matched by the corresponding matcher from the specified `itemMatchers`. Whilst matching, each traversal of the examined `Iterable` will stop as soon as a matching item is found. For example:

          assertThat(Arrays.asList("foo", "bar", "baz"), hasItems(endsWith("z"), endsWith("o")))

      Parameters:
        `itemMatchers` - the matchers to apply to items provided by the examined `Iterable`

    - #### hasItems

          @SafeVarargs
          public static <T> Matcher<java.lang.Iterable<T>> hasItems(T... items)

      Deprecated. As of version 2.1, use `IsIterableContaining.hasItems(Object[])`}.
      Creates a matcher for `Iterable`s that matches when consecutive passes over the examined `Iterable` yield at least one item that is equal to the corresponding item from the specified `items`. Whilst matching, each traversal of the examined `Iterable` will stop as soon as a matching item is found. For example:

          assertThat(Arrays.asList("foo", "bar", "baz"), hasItems("baz", "foo"))

      Parameters:
        `items` - the items to compare against the items provided by the examined `Iterable`
