All Implemented Interfaces:

IHierarchicalTableViewStateListener, IJaretTableModel, ITableNodeListener, java.beans.PropertyChangeListener, java.util.EventListener

public class StdHierarchicalTableModel
extends AbstractJaretTableModel
implements IHierarchicalTableViewStateListener, ITableNodeListener, java.beans.PropertyChangeListener

Implementation of a "normal" jaret table model based on a hierarchical jaret table model. The StdHierarchicalmodel will listen on propchanges if the nodes are PropertyObservables.

Constructor Detail

StdHierarchicalTableModel

public StdHierarchicalTableModel(IHierarchicalJaretTableModel hModel,
                                 IHierarchicalTableViewState hvs)

Construct a new stdhierarchical table model for a viewstate and a hierarchical model.

Parameters:

hModel - hierarchical table model

hvs - hierarchical viewstate

Method Detail

moreSiblings

public boolean moreSiblings(ITableNode node,
                            int level)

Check whether more siblings exist for a given node on a given level.

Parameters:

node - node

level - level

Returns:

true if more siblings exist (even with other parent)

getNextSibling

public ITableNode getNextSibling(ITableNode node)

Return the next sibling of a node.

Parameters:

node - node to get the next sibling for

Returns:

the sibling or null if there is none

isVisible

public boolean isVisible(ITableNode node)

Check whether a node is visible.

Parameters:

node - node to check

Returns:

true if the node is visible

getRow

public IRow getRow(int rowIdx)

Retrieve a specific row.

Specified by:

getRow in interface IJaretTableModel

Parameters:

rowIdx - index of the row

Returns:

the row

getRowCount

public int getRowCount()

Return the number of rows in the model.

Specified by:

getRowCount in interface IJaretTableModel

Returns:

number of rows

nodeAdded

public void nodeAdded(ITableNode parent,
                      ITableNode newChild)

Called when a node has been added.

Specified by:

nodeAdded in interface ITableNodeListener

Parameters:

parent - Parent of the new node.

newChild - the new node.

nodeRemoved

public void nodeRemoved(ITableNode parent,
                        ITableNode removedChild)

Called whenever a node is removed.

Specified by:

nodeRemoved in interface ITableNodeListener

Parameters:

parent - parent of the removed node.

removedChild - the removed node.

nodeExpanded
