GridDataSourceGridDataSource.getAvailableRows() may return a different number of rows than are actually available (i.e., the database
was changed between calls to GridDataSource.getAvailableRows() and the call to GridDataSource.prepare(int, int,
java.util.List)). In that case, this method should return null for any out-of-range indexes.getRowValue in interface GridDataSource5.6.4 - Copyright © 2003-2021 The Apache Software Foundation.
