KeyAccess 介绍

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 artists
List artists = Artist.queryObjects(conn);

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

// Get the number of classical albums
int 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 each
object 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());
}
});
