### Question:
LoopbackLinkFactory implements LinkFactory { @Override public boolean supports(LinkType linkType) { return LoopbackLink.LINK_TYPE.equals(linkType); } LoopbackLinkFactory(final PacketRejector packetRejector); Link<?> constructLink(
      final Supplier<InterledgerAddress> operatorAddressSupplier, final LinkSettings linkSettings
  ); @Override boolean supports(LinkType linkType);  }### Answer:
@Test public void supports() { assertThat(loopbackLinkFactory.supports(LoopbackLink.LINK_TYPE)).isEqualTo(true); assertThat(loopbackLinkFactory.supports(LinkType.of("foo"))).isEqualTo(false); }
