Java對象的SQL接口 JoSQL

JoSQL(SQLforJavaObjects)為Java開發者提供運用SQL語句來操作Java對象集的能力.利用JoSQL可以像操作數據庫中的數據一樣對任何Java對象集進行查詢,排序,分組。

示例用法

// Get a list of java.io.File objects.
List myObjs = getMyObjects ();

// Create a new Query.
Query q = new Query ();

// Parse the SQL you are going to use.
q.parse ("SELECT * FROM java.io.File WHERE name LIKE '%.java'");

// Execute the query.
QueryResults qr = q.execute (myObjs);

// Cycle over the query results.
List res = qr.getResults ();

for (int i = 0; i < res.size (); i++)
{

    File f = (File) res.get (i);

    // Do something with the File.

}
