All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel, javax.swing.tree.TreeModel

public class TreeDataModel
extends DataTable
implements javax.swing.tree.TreeModel

This class is an implementation of the TreeModel, that also supports (extends) DataTable. Used as a DataModel for the JTree(s) that are filled through DataTables. This data model supports only a 3 levels tree a Root, parents and children.

Constructor Detail

TreeDataModel

public TreeDataModel(java.lang.String rootName,
                     DataTable dataTable,
                     int colID,
                     int colVisible,
                     java.lang.String childrenSP)

Constructor

Parameters:

rootName - The tree Root name

dataTable - The DataTable representing the 2nd level of the tree.

colID - The Column indicating the ID in the DataTable.

colVisible - The Column to be displayed in the tree.

childrenSP - The Stored Procedure used to compose and retrieve the 3rd level of the tree.

Method Detail

getRoot

public java.lang.Object getRoot()

Retrieves the Root element of the tree.

Specified by:

getRoot in interface javax.swing.tree.TreeModel

Returns:

A TreeObject casted to Object.

getChild

public java.lang.Object getChild(java.lang.Object parent,
                                 int index)

Retreives the child object for a given parent at a given index. If the parent was the root, retrieves the object from the 2nd level DataTable. If the parent was an element (2nd level), retreives the corresponding 3rd level item

Specified by:

getChild in interface javax.swing.tree.TreeModel

Parameters:

parent - The parent TreeObject

index - The index within the children of the given parent.

Returns:

The designated child TreeObject casted to Object.

getChildCount

public int getChildCount(java.lang.Object parent)

Retrieves the Child Count for a specific parent.

Specified by:

getChildCount in interface javax.swing.tree.TreeModel

Parameters:

parent - The parent we need to get the child count for.

Returns:

The child count for the designated parent.

isLeaf

public boolean isLeaf(java.lang.Object node)

Indicates if this item is leaf or not. Returns always true if it is a 3rd level node and false otherwise.

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Parameters:

node - The Object to check for if Leaf or not.

Returns:

true if it is a 3rd level node and false otherwise.

valueForPathChanged

public void valueForPathChanged(javax.swing.tree.TreePath path,
                                java.lang.Object newValue)

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

getChildren

public TreeDataModel.TreeObject[] getChildren(javax.swing.tree.TreePath treePath)

Returnd the children at a specific tree path. Returns values only when the path contains 2 or 3 nodes.

Parameters:

treePath - The tree path used to find the children.

Returns:

A list of 3rd level TreeObject(s) representing the leafs of the given tree path.
