Cursors are used for operating on collections of 105records, for iterating over a database, and for saving handles to 106individual records, so that they can be modified after they have been 107read. 108<p> 109Cursors may be used by multiple threads, but only serially. That is, 110the application must serialize access to the handle. 111<p> 112If the cursor is to be used to perform operations on behalf of a 113transaction, the cursor must be opened and closed within the context of 114that single transaction. 115<p> 116Once the cursor close method has been called, the handle may not be 117accessed again, regardless of the close method's success or failure. 118<p> 119To obtain a cursor with default attributes: 120<blockquote><pre> 121 Cursor cursor = myDatabase.openCursor(txn, null); 122</pre></blockquote> 123To customize the attributes of a cursor, use a CursorConfig object. 124<blockquote><pre> 125 CursorConfig config = new CursorConfig(); 126 config.setDirtyRead(true); 127 Cursor cursor = myDatabase.openCursor(txn, config); 128</pre></blockquote> 129<p> 130Modifications to the database during a sequential scan will be reflected 131in the scan; that is, records inserted behind a cursor will not be 132returned while records inserted in front of a cursor will be returned. 133In Queue and Recno databases, missing entries (that is, entries that 134were never explicitly created or that were created and then deleted) 135will be ignored during a sequential scan. 136<P> 137 138<P> 139<HR> 140 141<P> 142 143<!-- ======== CONSTRUCTOR SUMMARY ======== --> 144 145<A NAME="constructor_summary"><!-- --></A> 146<TABLE BORDER="1" WIDTH="100%"
