    def isafter(self, start: int, end: int, immediately=False) -&gt; bool:
        &#34;&#34;&#34;
        Checks if this span is after the other span, i.e. the start of this annotation
        is after the end of the other annotation or span.

        Note: this can be called with an Annotation or AnnotationSet instead of `start` and `end`
          (see gatenlp._utils.support_annotation_or_set)

        Args:
          start: start offset of the span
