Constructor Detail

MutableTree

public MutableTree(N userObject)

Method Detail

getUserObject

public N getUserObject()

Description copied from interface: Tree

Gets the "content" of this tree node.

Specified by:

getUserObject in interface Tree<N>

Returns:

The user content of this node.

setParent

public void setParent(MutableTree<N> parent)

addChild

public void addChild(MutableTree<N> child)

removeChild

public void removeChild(MutableTree<N> child)

sortChildren

public void sortChildren(java.util.Comparator<Tree<N>> comparator)

Description copied from interface: Tree

Sorts the children using the specified comparator

Specified by:

sortChildren in interface Tree<N>

Parameters:

comparator - The comparator to be used for the sorting.

clearChildren

public void clearChildren()

getParent

public Tree<N> getParent()

Description copied from interface: Tree

Gets the parent of this tree node.

Specified by:

getParent in interface Tree<N>

Returns:

The parent tree node, or null if this node doesn't have a parent.

getChildren

public java.util.List<Tree<N>> getChildren()

Description copied from interface: Tree

Gets the children of this tree node.

Specified by:

getChildren in interface Tree<N>

Returns:

A list of children. If this tree node doesn't have any children then the list will be empty.

getChildCount

public int getChildCount()

Description copied from interface: Tree

A convenience method that gets the number of child nodes that this node has.

Specified by:

getChildCount in interface Tree<N>

Returns:

The count of the number of children of this node.

isRoot

public boolean isRoot()

Description copied from interface: Tree

Specified by:

isRoot in interface Tree<N>

Returns:

true if this is a root node, otherwise false.

isLeaf

public boolean isLeaf()

Description copied from interface: Tree

A convenience method that determines if this node is a leaf node (because it has no children).

Specified by:

isLeaf in interface Tree<N>

Returns:

true if this node is a leaf node otherwise false.

getRoot

public Tree<N> getRoot()

Description copied from interface: Tree

A convenience method that gets the root of this tree.

Specified by:

getRoot in interface Tree<N>

Returns:

The root node, which could be this node.

getPathToRoot

Specified by:

getPathToRoot in interface Tree<N>

getUserObjectPathToRoot

public java.util.List<N> getUserObjectPathToRoot()

Specified by:

getUserObjectPathToRoot in interface Tree<N>

getUserObjectClosure

Specified by:

getUserObjectClosure in interface Tree<N>

dump

public void dump(java.io.PrintWriter writer)

Specified by:

dump in interface Tree<N>

dump

public void dump(java.io.PrintWriter writer,
