ilog.cpl.list
Class IlpListModelSorter

java.lang.Object
  javax.swing.AbstractListModel
      ilog.cpl.list.IlpListModelSorter

All Implemented Interfaces:

Serializable, ListModel

public class IlpListModelSorter
extends AbstractListModel
implements ListModel

This ListModel implementation is used to sort the items in a list.

It encapsulates the ListModel to be sorted, as described in the decoration design pattern. IlpListModelSorter listens to the model it encapsulates and forwards the model changes to its own listeners according to the sorting parameters.

Since:

JTGO 3.0

Constructor Detail

IlpListModelSorter

public IlpListModelSorter()

Default constructor.

IlpListModelSorter

public IlpListModelSorter(ListModel model)

Creates a model sorter using the specified model. The model sorter listens to the given model.

Parameters:

model - The list model this sorter uses.

Method Detail

getModel

public ListModel getModel()

Retrieves the list model sorted by the model sorter.

Returns:

The ListModel encapsulated by the model sorter.

setModel

public void setModel(ListModel model)

Sets the list model to be sorted by the model sorter.

Parameters:

model - The list model to be sorted.

getComparator

public IlpMutableComparator getComparator()

Returns the comparator used to sort the underlying model.

Returns:

The comparator. May be null.

See Also:

setComparator(IlpMutableComparator)

setComparator

public void setComparator(IlpMutableComparator comparator)

Sets the comparator used to sort the underlying model.

Parameters:

comparator - The comparator. May be null. In this case, the model is not sorted, that is, this model exactly reflects the underlying model.

convertRowIndexToModel

public int convertRowIndexToModel(int viewRowIndex)

Maps the row in the view located at viewRowIndex to the index of the row in the list data source. Returns the index of the corresponding row in the list data source. If viewRowIndex is less than zero, returns viewRowIndex.

Parameters:

viewRowIndex - The index of the row in the view.

Returns:

The index of the corresponding row in the data source.

convertRowIndexToView

public int convertRowIndexToView(int modelRowIndex)

Maps the row in the list data source located at modelRowIndex to the index of the row in the view. Returns the index of the corresponding row in the view; returns -1 if the row is not displayed. If modelRowIndex is less than zero, returns modelRowIndex.

Parameters:

modelRowIndex - The index of the row in the data source.

Returns:

The index of the corresponding row in the view.

getSize

public int getSize()

Returns the length of the list.

Specified by:

getSize in interface ListModel

getElementAt

public Object getElementAt(int index)

Returns the value at the specified index.

Specified by:

getElementAt in interface ListModel

toString

public String toString()

Overrides:

toString in class Object
