RowSetIterator
It is the interface for Row Set Iterator. A Row Iterator is an iterator over a collection of View rows or Entity rows.
Usage
import oracle.jbo.Row; import oracle.jbo.RowSetIterator; public void rowTraverse() { //VO Instance XXLkpCodesVOImpl vo = getXXLkpCodesVO1(); //Row Instance XXLkpCodesVORowImpl row = null; int rowCount = vo.getFetchedRowCount(); //RowSetIterator Instance RowSetIterator saveItr = vo.createRowSetIterator("saveItr"); if (rowCount > 0) { //Set row range to zero, to traverse from beginning of VO rows collection saveItr.setRangeStart(0); saveItr.setRangeSize(rowCount); for (int i = 0; i < rowCount; i++) { row = (XXLkpCodesVORowImpl)saveItr.getRowAtRangeIndex(i); this.writeDiagnostics(this, "XX In AM - LkpCode " + row.getLookupCode(), 2); } } //Close row set iterator. saveItr.closeRowSetIterator(); } |
Note: Its suggestible to use only RowSetIterator while traversing through VO rows. Instead, if we use VO object to traverse through VO rows using vo.first() or vo.next() functions, there is more possibility that row data might get changed.
