Constructor Detail

ClassAndEntityTreeModel

public ClassAndEntityTreeModel(NamedObj root)

Create a new tree model with the specified root.

Parameters:

root - The root of the tree.

Method Detail

getChild

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

Get the child of the given parent at the given index. If the child does not exist, then return null.

Specified by:

getChild in interface javax.swing.tree.TreeModel

Overrides:

getChild in class EntityTreeModel

Parameters:

parent - A node in the tree.

index - The index of the desired child.

Returns:

A node, or null if there is no such child.

getChildCount

public int getChildCount(java.lang.Object parent)

Return the number of children of the given parent. This is the number classes and contained entities, filtered by the filter specified by setFilter(), if any has been specified.

Specified by:

getChildCount in interface javax.swing.tree.TreeModel

Overrides:

getChildCount in class EntityTreeModel

Parameters:

parent - A parent node.

Returns:

The number of children.

getIndexOfChild

public int getIndexOfChild(java.lang.Object parent,
                           java.lang.Object child)

Return the index of the given child within the given parent. If the parent is not contained in the child, return -1.

Specified by:

getIndexOfChild in interface javax.swing.tree.TreeModel

Overrides:

getIndexOfChild in class EntityTreeModel

Parameters:

parent - The parent.

child - The child.

Returns:

The index of the specified child.

isLeaf

public boolean isLeaf(java.lang.Object object)

Return true if the object is a leaf node. An object is a leaf node if it has no children that are instances of one of the classes specified by setFilter(), if a filter has been specified.

Specified by:

isLeaf in interface javax.swing.tree.TreeModel

Overrides:

isLeaf in class EntityTreeModel

Parameters:

object - The object.

Returns:

True if the node has no children.

_classes

protected java.util.List _classes(java.lang.Object object)

Return the list of classes, or an empty list if there are none. Override this method if you wish to show only a subset of the classes.

Parameters:

object - The object.

Returns:

A list of classes.
