我在互联网上搜索了类似于我正在做的事情,但却找不到任何东西。我在Java 8中使用接口创建了一个Builder模式,如下所示:
public class UrlImmutable {
public final String parentUrl;
public final Double parentUrlSentiment;
public final Set<String> childUrls;
public final boolean isParentVendorUrl;
public final Map<TagClassification, Set<String>> parentUrlArticleTags;
private UrlImmutable(String parentUrl, Double parentUrlSentiment, Set<String> childUrls, boolean isParentVendorUrl,
Map<TagClassification, Set<String>> parentUrlArticleTags ) {
super();
this.parentUrl = parentUrl;
this.parentUrlSentiment = parentUrlSentiment;
this.childUrls = childUrls;
this.isParentVendorUrl = isParentVendorUrl;
this.parentUrlArticleTags = parentUrlArticleTags;
}
/** Our Interfaces for the Builder **/
public interface ParentUrlBuilder {
ParentUrlSentimentBuilder parentUrl(String parentUrl);
}
public interface ParentUrlSentimentBuilder {
ChildUrlBuilder parentUrlSentiment(Double parentUrlSentiment);
}
public interface ChildUrlBuilder {
IsVendorUrlBuilder childUrls(Set<String> childUrls);
}
public interface IsVendorUrlBuilder {
ParentUrlArticleTagsBuilder isParentVendorUrl(boolean isParentVendorUrl);
}
public interface ParentUrlArticleTagsBuilder {
UrlImmutable parentUrlArticleTags(Map<TagClassification,Set<String>> parentUrlArticleTags);
}
public static ParentUrlBuilder discoveredUrl() {
return parentUrl -> parentUrlSentiment -> childUrls -> isParentVendorUrl -> parentUrlArticleTags ->
new UrlImmutable(parentUrl, parentUrlSentiment, childUrls, isParentVendorUrl, parentUrlArticleTags);
}
}
为了构建这个对象,我们这样做:
UrlImmutable url =
UrlImmutable()
.parentUrl("http://www.google.com")
.parentUrlSentiment(10.5)
.childUrls(childUrls)
.isParentVendorUrl(true)
.parentUrlArticleTags(parentUrlArticleTags);
我似乎无法为此找到正确的注释组合。任何帮助非常感谢!
