- All Implemented Interfaces:
- java.util.EventListener, java.io.Serializable, javax.swing.table.TableModel, javax.swing.event.TableModelListener
- public class TableSorter
- extends TableMap
A sorter for TableModels. The sorter has a model (conforming to TableModel)
and itself implements TableModel. TableSorter does not store or copy
the data in the TableModel, instead it maintains an array of
integers which it keeps the same size as the number of rows in its
model. When the model changes it notifies the sorter that something
has changed eg. "rowsAdded" so that its internal array of integers
can be reallocated. As requests are made of the sorter (like
getValueAt(row, col) it redirects them to its model via the mapping
array. That way the TableSorter appears to hold another copy of the table
with the rows in a different order. The sorting algorthm used is stable
which means that it does not move around rows when its comparison
function returns 0 to denote that they are equivalent.
