Class CursorQuery<T>

java.lang.Object

de.greenrobot.dao.query.CursorQuery<T>

Type Parameters:

T - The entity class the query will return results for.

public class CursorQuery<T>
extends java.lang.Object

A repeatable query returning a raw android.database.Cursor. Note, that using cursors is usually a hassle and greenDAO provides a higher level abstraction using entities (see Query). This class can nevertheless be useful to work with legacy code that is based on Cursors or CursorLoaders.
