Basically, the prepare() method is used to fetch the rows between startIndex and endIndex in a single batch and cache them. This cache might be a list with indexes ranging from 0 to (endIndex - startIndex)
getRowValue(int index) is then used to retrieve a single entry from the batch. This might require you to subtract startIndex from index to get a suitable index into your cached batch of records. getAvailableRows() can be a dynamic value over time. Just make sure you return null from getRowValue() if the index is out of range (ie a row has been deleted). -- View this message in context: http://tapestry.1045711.n5.nabble.com/5-3-6-GridDataSource-provided-row-index-to-getRowValue-int-tp5718694p5718727.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
