Constructor Detail

FilterTreeModel

public FilterTreeModel(ITreeModel model)
Method Detail

dispose

public void dispose()
Specified by:
dispose in interface IDisposable
Overrides:
dispose in class ProxyTreeModel

setFilter

public void setFilter(IObjectAcceptor value)

getFilter

public IObjectAcceptor getFilter()

setFiltering

public void setFiltering(boolean value)

isFiltering

public boolean isFiltering()

getRoot

public java.lang.Object getRoot()
Description copied from interface: ITreeModel
Returns the root of the tree. Returns null only if the tree has no nodes.

Specified by:
getRoot in interface ITreeModel
Overrides:
getRoot in class ProxyTreeModel
Returns:
the root of the tree

getChildCount

public int getChildCount(java.lang.Object parent)
Description copied from interface: ITreeModel
Returns the number of children of parent. Returns 0 if the node is a leaf or if it has no children. parent must be a node previously obtained from this data source.

Specified by:
getChildCount in interface ITreeModel
Overrides:
getChildCount in class ProxyTreeModel
Parameters:
parent - a node in the tree, obtained from this data source
Returns:
the number of children of the node parent

isLeaf

public boolean isLeaf(java.lang.Object node)
Description copied from interface: ITreeModel
Returns true if node is a leaf. It is possible for this method to return false even if node has no children. A directory in a filesystem, for example, may contain no files; the node representing the directory is not a leaf, but it also has no children.

Specified by:
isLeaf in interface ITreeModel
Overrides:
isLeaf in class ProxyTreeModel
Parameters:
node - a node in the tree, obtained from this data source
Returns:
true if node is a leaf

getChild

public java.lang.Object getChild(java.lang.Object parent,
                                 int index)
Description copied from interface: ITreeModel
Returns the child of parent at index index in the parent's child array. parent must be a node previously obtained from this data source. This should not return null if index is a valid index for parent (that is index >= 0 && index < getChildCount(parent)).

Specified by:
getChild in interface ITreeModel
Overrides:
getChild in class ProxyTreeModel
Parameters:
parent - a node in the tree, obtained from this data source
Returns:
the child of parent at index index

getIndexOfChild

public int getIndexOfChild(java.lang.Object parent,
                           java.lang.Object child)
Description copied from interface: ITreeModel
Returns the index of child in parent. If parent is null or child is null, returns -1.

Specified by:
getIndexOfChild in interface ITreeModel
Overrides:
getIndexOfChild in class ProxyTreeModel
Parameters:
parent - a note in the tree, obtained from this data source
child - the node we are interested in
Returns:
the index of the child in the parent, or -1 if either child or parent are null

rebuildSubTree

protected void rebuildSubTree(java.lang.Object[] path)

isVisible

protected boolean isVisible(java.lang.Object[] path)

subModelNodesChanged

protected void subModelNodesChanged(TreeModelEvent e)
Overrides:
subModelNodesChanged in class ProxyTreeModel

subModelNodesInserted

protected void subModelNodesInserted(TreeModelEvent e)
Overrides:
subModelNodesInserted in class ProxyTreeModel

subModelNodesRemoved

protected void subModelNodesRemoved(TreeModelEvent e)
Overrides:
subModelNodesRemoved in class ProxyTreeModel

subModelStructureChanged

protected void subModelStructureChanged(TreeModelEvent e)
Overrides:
subModelStructureChanged in class ProxyTreeModel
