Cursors are used for operating on collections of 108records, for iterating over a database, and for saving handles to 109individual records, so that they can be modified after they have been 110read. 111<p> 112Cursors may be used by multiple threads, but only serially. That is, 113the application must serialize access to the handle. 114<p> 115If the cursor is to be used to perform operations on behalf of a 116transaction, the cursor must be opened and closed within the context of 117that single transaction. 118<p> 119Once the cursor close method has been called, the handle may not be 120accessed again, regardless of the close method's success or failure. 121<p> 122To obtain a cursor with default attributes: 123<blockquote><pre> 124 Cursor cursor = myDatabase.openCursor(txn, null); 125</pre></blockquote> 126To customize the attributes of a cursor, use a CursorConfig object. 127<blockquote><pre> 128 CursorConfig config = new CursorConfig(); 129 config.setDirtyRead(true); 130 Cursor cursor = myDatabase.openCursor(txn, config); 131</pre></blockquote> 132<p> 133Modifications to the database during a sequential scan will be reflected 134in the scan; that is, records inserted behind a cursor will not be 135returned while records inserted in front of a cursor will be returned. 136In Queue and Recno databases, missing entries (that is, entries that 137were never explicitly created or that were created and then deleted) 138will be ignored during a sequential scan. 139<P> 140 141<P> 142<HR> 143 144<P> 145 146<!-- ======== CONSTRUCTOR SUMMARY ======== --> 147 148<A NAME="constructor_summary"><!-- --></A> 149<TABLE BORDER="1" WIDTH="100%"
