Constructor Detail

AbstractTreeNode

public AbstractTreeNode()

Creates an empty AbstractTreeNode without child nodes and an empty list of TreeNodeChangeListeners. The pointer to the parent of this node is set to null.

AbstractTreeNode

public AbstractTreeNode(javax.swing.tree.TreeNode node)

Constructor for cloning. AbstractTreeNode has two properties: parent and listOfListeners. Both of them are not cloned by this method, for two reasons:

• The parent is not cloned and is left as null because the new AbstractTreeNode will get a parent set as soon as it is added/linked again to a Model. Note that only the top-level element of the cloned sub-tree will have a null value as its parent. All sub-element will point to their correct parent element.
• listOfListeners is needed in all other setXX() methods. Cloning these might lead to strange and unexpected behavior, because when doing a deep cloning, the listeners of the old object would suddenly be informed about all value changes within this new object. Since we do cloning, all values of all child elements have to be touched, i.e., all listeners would be informed many times, but each time receive the identical value as it was before. Since it is totally unclear of which type listeners are, a deep cloning of these is not possible.

Therefore, it is necessary to keep in mind that the parent of the clone will be null and that you have to care by yourself if you are using TreeNodeChangeListeners.

Parameters:

node - The original TreeNode to be cloned.

Method Detail

indexOf

public static int indexOf(javax.swing.tree.TreeNode parent,
          javax.swing.tree.TreeNode child)

Searches the given child in the list of sub-nodes of the parent element.

Parameters:

parent -

child -

Returns:

the index of the child in the parent's list of children or -1 if no such child can be found.

addAllChangeListeners

public boolean addAllChangeListeners(java.util.Collection<TreeNodeChangeListener> listeners)

Description copied from interface: TreeNodeWithChangeSupport

Adds recursively all given TreeNodeChangeListener instances to this element.

Specified by:

addAllChangeListeners in interface TreeNodeWithChangeSupport

Parameters:

listeners - the set of listeners to add

Returns:

true if the set of listeners is added with success.

addTreeNodeChangeListener

public void addTreeNodeChangeListener(TreeNodeChangeListener listener)

Description copied from interface: TreeNodeWithChangeSupport

Adds recursively a listener to the TreeNodeWithChangeSupport object and all of its sub-elements. Calling this method is effectively identical to the call TreeNodeWithChangeSupport.addTreeNodeChangeListener(TreeNodeChangeListener, boolean) where recursively = true.

Specified by:

addTreeNodeChangeListener in interface TreeNodeWithChangeSupport

Parameters:

listener - the listener to add

See Also:

TreeNodeWithChangeSupport.addTreeNodeChangeListener(TreeNodeChangeListener, boolean)

addTreeNodeChangeListener

public void addTreeNodeChangeListener(TreeNodeChangeListener listener,
                             boolean recursive)

Description copied from interface: TreeNodeWithChangeSupport

Adds a listener to this TreeNodeWithChangeSupport object and optionally also to all of its child nodes.

Specified by:

addTreeNodeChangeListener in interface TreeNodeWithChangeSupport

Parameters:

listener - the listener to add

recursive - if true the given listener will be added to this node and also recursively to all of its child nodes. If false, the listener will only be added to the current node.

See Also:

TreeNodeWithChangeSupport.addTreeNodeChangeListener(TreeNodeChangeListener)

children

public java.util.Enumeration<javax.swing.tree.TreeNode> children()

Specified by:

children in interface javax.swing.tree.TreeNode

clearUserObjects

public void clearUserObjects()

Description copied from interface: TreeNodeWithChangeSupport

Removes all of the mappings from the map of user objects (optional operation). The map will be empty after this call returns.

Specified by:

filter

public java.util.List<? extends javax.swing.tree.TreeNode> filter(Filter filter)

Description copied from interface: TreeNodeWithChangeSupport

Filters this tree data structure recursively and returns a list of all TreeNodes that are accepted by the Filter. Although internal nodes that do not satisfy the filter criterion by themselves are not contained in the resulting list, the recursion continues at their children.

Specified by:

filter in interface TreeNodeWithChangeSupport

Parameters:

filter - A criterion to select a sub-set of nodes of this tree.

Returns:

A List of TreeNodes that do all satisfy the criterion of the given Filter.

See Also:

TreeNodeWithChangeSupport.filter(Filter, boolean)

filter

public java.util.List<? extends javax.swing.tree.TreeNode> filter(Filter filter,
                                                         boolean retainInternalNodes)

Description copied from interface: TreeNodeWithChangeSupport

Filters this tree data structure recursively and returns a list of all TreeNodes that are accepted by the Filter. The second argument decides whether or not internal nodes that do not by themselves satisfy the filter criterion should still be retained in the result list.

Specified by:

filter in interface TreeNodeWithChangeSupport

Parameters:

filter - A criterion to select a sub-set of nodes of this tree.

retainInternalNodes - Decides if internal nodes should also be included in the resulting List if they do not by themselves satisfy the Filter but if these do have child elements that do so. This might be useful in order to obtain a complete tree path to interesting sub-elements.

Returns:

A List representing a subset of TreeNodes that satisfy the Filter's criterion, or whose child nodes do so.

See Also:

TreeNodeWithChangeSupport.filter(Filter)

filter

public java.util.List<? extends javax.swing.tree.TreeNode> filter(Filter filter,
                                                         boolean retainInternalNodes,
                                                         boolean prune)

Description copied from interface: TreeNodeWithChangeSupport

Filters this tree data structure recursively and returns a list of all TreeNodes that are accepted by the Filter. The two boolean switches let you decide if internal nodes that do not by themselves satisfy the filter criterion should be retained in the list, and if the recursion should be aborted as soon as the first hit is discovered.

Specified by:

filter in interface TreeNodeWithChangeSupport

retainInternalNodes - decides whether or not internal nodes should be added to the list of results even though these might not by themselves satisfy the filter's criterion, but whose children do. This feature can be useful, e.g., in order to keep the full tree path to nodes of interest

prune - if this argument is true, the recursive search is aborted upon the discovery of the first hit.

Returns:

A List representing a subset of TreeNodes that satisfy the Filter's criterion, or whose child nodes do so.

See Also:

TreeNodeWithChangeSupport.filter(Filter, boolean)
