接口 Matcher<T>

    • 方法详细资料

      • matches

        boolean matches​(Object item)
        Evaluates the matcher for argument item.

        This method matches against Object, instead of the generic type T. This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type.

        参数:
        item - the object against which the matcher is evaluated.
        返回:
        true if item matches, otherwise false.

      • describeMismatch

        void describeMismatch​(Object item,
                              Description mismatchDescription)
        Generate a description of why the matcher has not accepted the item. The description will be part of a larger description of why a matching failed, so it should be concise. This method assumes that matches(item) is false, but will not check this.
        参数:
        item - The item that the Matcher has rejected.
        mismatchDescription - The description to be built or appended to.
