Query — Wikipedia API Response Wrapper (wiki-common)

The Query class is the top-level deserialization target for the Wikipedia Recent Changes API JSON response. It wraps a RecentChanges object, mirroring the two-level nesting that the Wikipedia API uses to return query results.

import lombok.Data;

@Data
public class Query {
    private RecentChanges query;
}

Fields

query

RecentChanges

The nested query object from the Wikipedia API response. Contains a RecentChanges instance, which in turn holds the list of individual Change records returned by the API call.

Example

The full Wikipedia Recent Changes API JSON structure that Jackson deserializes into a Query instance:

{
  "query": {
    "recentchanges": [
      {
        "type": "edit",
        "title": "Albert Einstein",
        "pageid": 736,
        "tags": []
      }
    ]
  }
}

Show Deserialization chain

Jackson maps the top-level query key to Query.query (a RecentChanges object), then maps recentchanges inside it to RecentChanges.recentChanges (a List<Change>). Each element in that list is deserialized into a Change instance.

Query.query
  └── RecentChanges.recentChanges
        └── List<Change>

Notes

WikipediaClient.getRecentChanges() returns an instance of Query after deserializing the raw HTTP response body from the Wikipedia API. Callers unwrap the list of changes via query.getQuery().getRecentChanges().

The @Data annotation from Lombok generates getters, setters, equals, hashCode, and toString implementations at compile time.

This class is provided by the wiki-common module (com.as:wiki-common:0.0.1-SNAPSHOT).
