setAllowsChildren

public final void setAllowsChildren(boolean allowsChildren)

Specified by:

isLeaf

public boolean isLeaf()

Specified by:

isLeaf in interface TreeNode

children

public final Enumeration children()

Specified by:

children in interface TreeNode

iterator

public final Iterator<IterableTreeNode<?>> iterator()

Specified by:

iterator in interface Iterable<O>

isEmpty

public final boolean isEmpty()

Specified by:

getUserObject

public final O getUserObject()

Specified by:

getUserObject in interface IterableTreeNode<O>

setUserObject

public final void setUserObject(O userObject)

Specified by:

addChild

public final void addChild(IterableTreeNode<?> newChild)

Specified by:

addChild in interface IterableTreeNode<O>

insertChild

public final void insertChild(IterableTreeNode<?> newChild,
                              int position)

Specified by:

insertChild in interface IterableTreeNode<O>

removeChild

public final void removeChild(IterableTreeNode<?> child)

Description copied from interface: IterableTreeNode

Remove given given child.

Will throw exception if given child is not a child of this node.

Specified by:

removeChild in interface IterableTreeNode<O>

Parameters:

child - child to remove

removeChild

public final void removeChild(int index)

Description copied from interface: IterableTreeNode

Remove child at given index.

Will throw exception if no child at index.

Specified by:

removeChild in interface IterableTreeNode<O>

Parameters:

index - position of child to remove

removeChildren

public void removeChildren()

Description copied from interface: IterableTreeNode

Removes all of this node's children, setting their parents to null. If this node has no children, this method does nothing.

Specified by:

removeChildren in interface IterableTreeNode<O>

removeChildren

public void removeChildren(List<IterableTreeNode<?>> children)

Description copied from interface: IterableTreeNode

Remove given children. Acts as method IterableTreeNode.removeChild(IterableTreeNode) for each element.

Specified by:

removeChildren in interface IterableTreeNode<O>

Parameters:

children - children to remove

isNodeAncestor

public final boolean isNodeAncestor(IterableTreeNode anotherNode)

Returns true if anotherNode is an ancestor of this node -- if it is this node, this node's parent, or an ancestor of this node's parent. (Note that a node is considered an ancestor of itself.) If anotherNode is null, this method returns false. This operation is at worst O(h) where h is the distance from the root to this node.

Parameters:

anotherNode - node to test as an ancestor of this node

Returns:

true if this node is a descendant of anotherNode
