KeyAccess- ORM框架

KeyAccess 是一个轻量级的对象关系映射框架（ORM），利用现有数据库生成对象模型。

示例代码：

// All artistsList artists = Artist.queryObjects(conn);

// Artists with a good ratingList newArtists = Artist.queryObjects(conn, “rating > 4”);

// Get the number of classical albumsint numClassicalAlbums = Album.queryCount(conn, “type = ‘CLASSICAL’ “);

// Load single object by one or more primary keys (vararg)Artist artist = Artist.queryObjectByKey(conn, 294);

// Load all objects, but not into a list: call a callback function for eachobject instead.// This can dramatically reduce memory requirements if you need to process// thousands of objects. There is also a version available where you can// supply a where clause.Artist.queryObjects(conn, new IObjectLoadHandler(){public void onLoad(Object obj){System.out.println(“Artist: “+ ((Artist)obj).getName());}});
