Class GlazedListsDataProvider<T>

java.lang.Object
org.eclipse.nebula.widgets.nattable.data.ListDataProvider<T>
org.eclipse.nebula.widgets.nattable.extension.glazedlists.GlazedListsDataProvider<T>
All Implemented Interfaces:
IDataProvider, IRowDataProvider<T>
@Deprecated public class GlazedListsDataProvider<T> extends ListDataProvider<T>
Deprecated.
Use a default ListDataProvider instead as the performance boost can not be verified with current Java and GlazedLists implementations and as this implementation is not thread-safe it introduces more issues than it tries to solve.
This class implements "last row" caching for much faster column value access on the table. As normally the default implementation would fetch the row object for each cell in a column, we know what the last row we fetched was, and if it's a re-request of the same row as last time, we simply return the last cached row object (assuming the list didn't change in some important way, as then we clear out our cache).
