All Implemented Interfaces:

ReorderModel, TreeTableModel, Serializable, TreeModel

Direct Known Subclasses:

DefaultTreeTableColumnModel, ListTreeTableModel

public abstract class ObjectTreeTableModel
extends ComparableTreeTableModel

ObjectTreeTableModel is a treetable model whose nodes' cell value depends on an abstract Object. The object at each node is the user object of a DefaultMutableTreeNode.

The value at each treetable cell is retrieved with the getObjectAt method.

Method Detail

getObjectAt

public abstract Object getObjectAt(Object object,
                                   int column)

Returns the value for object at column

Parameters:

object - the object whose value is to be queried

column - the column whose value is to be queried

Returns:

the value of the Object at the specified index

getValueAt

public Object getValueAt(Object node,
                         int column)

Returns the value to be displayed for node, at column index column.

Parameters:

node - the node to query

column - the column index

Returns:

the value

createLeafNode

protected DefaultMutableTreeNode createLeafNode(Object o)

Creates and returns a new instance of a leaf node whose 'column data' is identified by data. data in this framework is either DefaultMutableTreeNode's user object attribute or the aggregate values of a TreeTableRow.

Specified by:

createLeafNode in class ComparableTreeTableModel

Parameters:

o - the node's 'column data'.

Returns:

the newly created leaf node.

replicateLeafNode

protected DefaultMutableTreeNode replicateLeafNode(DefaultMutableTreeNode child)

Creates and returns a new instance of the leaf node identified by child. This method is used when the underlying comparators have changed, so that the tree can be restructured.

Specified by:

replicateLeafNode in class ComparableTreeTableModel

Parameters:

child - the leaf we want to create a replica of.

Returns:

the newly created leaf node.

createNonLeafNode

protected DefaultMutableTreeNode createNonLeafNode(DefaultMutableTreeNode child)

Creates and returns a new instance of a group (non-leaf) node whose child is identified by child.

Specified by:

createNonLeafNode in class ComparableTreeTableModel

Parameters:

child - this node's child (or one of its children)

Returns:

the newly created group (non-leaf) node.

setObjectAt

public void setObjectAt(Object aValue,
                        Object object,
                        int column)

Sets the value for node at column to aValue.

Parameters:

aValue - the new value

object - the object whose value is to be altered

column - the column whose value is to be altered

setValueAt

public void setValueAt(Object aValue,
                       Object node,
                       int column)

Sets the value for node at columnIndex to aValue.

Specified by:

setValueAt in interface TreeTableModel

Overrides:

setValueAt in class MutableTreeTableModel

Parameters:

aValue - the new value

node - the node whose value is to be changed

column - the column whose value is to be changed
