Constructor Detail

FilteredVisibleTreeModel

public FilteredVisibleTreeModel(javax.swing.tree.TreeModel model,
                                java.io.File filterFile)

Method Detail

getChild

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

Description copied from class: FullTreeModel

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 FullTreeModel

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)

Description copied from class: FullTreeModel

Return the number of children of the given parent. This is the number attributes, ports, relations, 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 FullTreeModel

Parameters:

parent - A parent node.

Returns:

The number of children.

getIndexOfChild

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

Description copied from class: FullTreeModel

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 FullTreeModel

Parameters:

parent - The parent.

child - The child.

Returns:

The index of the specified child.

getRoot

public java.lang.Object getRoot()

Description copied from class: EntityTreeModel

Get the root of this tree model.

Specified by:

getRoot in interface javax.swing.tree.TreeModel

Overrides:

getRoot in class EntityTreeModel

Returns:

A NamedObj, usually an Entity.

See Also:

EntityTreeModel.setRoot(NamedObj)

isLeaf

public boolean isLeaf(java.lang.Object node)

Description copied from class: VisibleTreeModel

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 VisibleTreeModel

Parameters:

node - The object.

Returns:

True if the node has no children.

valueForPathChanged

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

Description copied from class: VisibleTreeModel

Override the base class to do nothing. This seems risky, but the problem is that without it, every time you expand a library that has a image or PDF icon it, the entire library collapses, which is extremely annoying. I guess this is OK under the assumption that the library does not change during execution.

Specified by:

valueForPathChanged in interface javax.swing.tree.TreeModel

Overrides:

valueForPathChanged in class VisibleTreeModel

Parameters:

path - The path of the node that has changed.

newValue - The new value of the node.

addTreeModelListener

public void addTreeModelListener(javax.swing.event.TreeModelListener l)

Description copied from class: EntityTreeModel

Add a listener to this model.

Specified by:

addTreeModelListener in interface javax.swing.tree.TreeModel

Overrides:

addTreeModelListener in class EntityTreeModel

Parameters:

l - The listener to add.

See Also:

EntityTreeModel.removeTreeModelListener(TreeModelListener)

removeTreeModelListener

public void removeTreeModelListener(javax.swing.event.TreeModelListener l)

Description copied from class: EntityTreeModel

Remove the specified listener.

Specified by:

removeTreeModelListener in interface javax.swing.tree.TreeModel

Overrides:

removeTreeModelListener in class EntityTreeModel

Parameters:

l - The listener to remove.

See Also:

EntityTreeModel.addTreeModelListener(TreeModelListener)
