  • All Implemented Interfaces:
    Matcher<T[]>, SelfDescribing

    public class IsArray<T>
    extends TypeSafeMatcher<T[]>
    Matcher for array whose elements satisfy a sequence of matchers. The array size must equal the number of element matchers.

      • matchesSafely

        public boolean matchesSafely​(T[] array)
        Description copied from class: TypeSafeMatcher
        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 TypeSafeMatcher<T[]>
      • describeMismatchSafely

        public void describeMismatchSafely​(T[] actual,
                                           Description mismatchDescription)
        Description copied from class: TypeSafeMatcher
        Subclasses should override this. The item will already have been checked for the specific type and will never be null.
        Overrides:
        describeMismatchSafely in class TypeSafeMatcher<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.
      • descriptionStart

        protected java.lang.String descriptionStart()
        Returns the string that starts the description. Can be overridden in subclasses to customise how the matcher is described.
      • descriptionSeparator

        protected java.lang.String descriptionSeparator()
        Returns the string that separates the elements in the description. Can be overridden in subclasses to customise how the matcher is described.
      • descriptionEnd

        protected java.lang.String descriptionEnd()
        Returns the string that ends the description. Can be overridden in subclasses to customise how the matcher is described.
      • array

        public static <T> IsArray<T> array​(Matcher<? super T>... elementMatchers)
        Creates a matcher that matches arrays whose elements are satisfied by the specified matchers. Matches positively only if the number of matchers specified is equal to the length of the examined array and each matcher[i] is satisfied by array[i].

        For example:

        assertThat(new Integer[]{1,2,3}, is(array(equalTo(1), equalTo(2), equalTo(3))))
        Parameters:
        elementMatchers - the matchers that the elements of examined arrays should satisfy
