Package jadex.commons.gui.jtreetable

Class DynamicTreeTableModel

java.lang.Object

jadex.commons.gui.jtreetable.AbstractTreeTableModel

jadex.commons.gui.jtreetable.DynamicTreeTableModel

All Implemented Interfaces:

TreeTableModel, javax.swing.tree.TreeModel

public class DynamicTreeTableModel
extends AbstractTreeTableModel

An implementation of TreeTableModel that uses reflection to answer TableModel methods. This works off a handful of values. A TreeNode is used to answer all the TreeModel related methods (similiar to AbstractTreeTableModel and DefaultTreeModel). The column names are specified in the constructor. The values for the columns are dynamically obtained via reflection, you simply provide the method names. The methods used to set a particular value are also specified as an array of method names, a null method name, or null array indicates the column isn't editable. And the class types, used for the TableModel method getColumnClass are specified in the constructor.

DynamicTreeTableModel

                             java.lang.String[] columnNames,
                             java.lang.String[] getterMethodNames,

                             java.lang.Class[] cTypes)

Constructor for creating a DynamicTreeTableModel.

Method Detail

getChildCount

public int getChildCount(java.lang.Object node)

TreeModel method to return the number of children of a particular node. Since node is a TreeNode, this can be answered via the TreeNode method getChildCount.

getChild

public java.lang.Object getChild(java.lang.Object node,
                                 int i)

TreeModel method to locate a particular child of the specified node. Since node is a TreeNode, this can be answered via the TreeNode method getChild.

isLeaf

public boolean isLeaf(java.lang.Object node)

TreeModel method to determine if a node is a leaf. Since node is a TreeNode, this can be answered via the TreeNode method isLeaf.

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Overrides:

isLeaf in class AbstractTreeTableModel

getColumnCount

public int getColumnCount()

Returns the number of column names passed into the constructor.

getColumnName

public java.lang.String getColumnName(int column)

Returns the column name passed into the constructor.

getColumnClass

public java.lang.Class getColumnClass(int column)

Returns the column class for column column. This is set in the constructor.

Specified by:

getColumnClass in interface TreeTableModel

Overrides:

getColumnClass in class AbstractTreeTableModel

getValueAt

public java.lang.Object getValueAt(java.lang.Object node,
                                   int column)

Returns the value for the column column and object node. The return value is determined by invoking the method specified in constructor for the passed in column.

isCellEditable

public boolean isCellEditable(java.lang.Object node,
                              int column)

Returns true if there is a setter method name for column column. This is set in the constructor.

Specified by:

isCellEditable in interface TreeTableModel

Overrides:

isCellEditable in class AbstractTreeTableModel

setValueAt

public void setValueAt(java.lang.Object aValue,
                       java.lang.Object node,
                       int column)

Sets the value to aValue for the object node in column column. This is done by using the setter method name, and coercing the passed in value to the specified type.

Specified by:

setValueAt in interface TreeTableModel

Overrides:

setValueAt in class AbstractTreeTableModel
