protected int compareRowsByColumn(int row1,
                                  int row2,
                                  int column)

getValueAt

public Object getValueAt(int aRow,
                         int aColumn)

Specified by:

getValueAt in interface TableModel

Overrides:

getValueAt in class JvTableMap

mapRow

public int mapRow(int aRow)

n2sort

protected void n2sort()

reallocateIndexes

protected void reallocateIndexes()

setModel

public void setModel(TableModel model)

Overrides:

setModel in class JvTableMap

setValueAt

public void setValueAt(Object aValue,
                       int aRow,
                       int aColumn)

Specified by:

setValueAt in interface TableModel

Overrides:

setValueAt in class JvTableMap

shuttlesort

protected void shuttlesort(int[] from,
                           int[] to,
                           int low,
                           int high)

sort

public void sort(Object sender)

setSortColumn

public void setSortColumn(int columnIndex)

Description copied from interface: JvSortableTableModel

Sort the rows by the column with the specified table model index.

Specified by:

setSortColumn in interface JvSortableTableModel

Parameters:

columnIndex - the index of the column, or -1 for no sorting

getSortColumn

public int getSortColumn()

Description copied from interface: JvSortableTableModel

Returns the table model index of the column the model is sorted on.

Specified by:

getSortColumn in interface JvSortableTableModel

Returns:

the index of the sort column, or -1 if not sorted

setAscending

public void setAscending(boolean ascending)

Description copied from interface: JvSortableTableModel

Set whether the sort is ascending or descending.

Specified by:

setAscending in interface JvSortableTableModel

Parameters:

ascending - true if the sort is ascending, false otherwise

isAscending

public boolean isAscending()

Description copied from interface: JvSortableTableModel

Return whether the sort is ascending or descending.

Specified by:

isAscending in interface JvSortableTableModel

Returns:

true if the sort is ascending, false otherwise

sortByColumn

public void sortByColumn(int columnIndex,
                         boolean ascending)

Description copied from interface: JvSortableTableModel

Set the column to sort by and whether the sort is ascending or descending in one swoop. Using this method is equivalent to a call to JvSortableTableModel.setSortColumn(int) and a call to JvSortableTableModel.setAscending(boolean) but only causes a single sort of the data instead of two.

Specified by:

sortByColumn in interface JvSortableTableModel

Parameters:

columnIndex - the index of the column, or -1 for no sorting

ascending - true if the sort is ascending, false otherwise

swap

protected final void swap(int i,
                          int j)

tableChanged

public void tableChanged(TableModelEvent e)

Specified by:

tableChanged in interface TableModelListener

Overrides:

tableChanged in class JvTableMap

getObjectAt

public Object getObjectAt(int row)

Return the domain object associated with the specified row.

Specified by:

getObjectAt in interface JvObjectTableModel

Parameters:

row - the index of the desired row

Returns:

the domain object for the specified row

getEmptyCollection

public Collection getEmptyCollection()

Return an empty collection suitable for putting the selected items within.

Specified by:

getEmptyCollection in interface JvObjectTableModel

Returns:

an empty collection
