### Question:
WFS_1_1_0_Protocol implements WFSProtocol { public URI getServiceProviderUri() { ServiceProviderType serviceProvider = capabilities.getServiceProvider(); if (serviceProvider == null) { return null; } OnlineResourceType providerSite = serviceProvider.getProviderSite(); if (providerSite == null) { return null; } String href = providerSite.getHref(); if (href == null) { return null; } try { return new URI(href); } catch (URISyntaxException e) { return null; } } WFS_1_1_0_Protocol(InputStream capabilitiesReader, HTTPClient http,
