Constructor Detail

TreeProxy

public TreeProxy(Tree tree)

Method Detail

getTree

public Tree getTree()

addNode

public int addNode(int par)

Description copied from interface: Tree

Adds a node to the tree.

Specified by:

addNode in interface Tree

Parameters:

par - the parent of the node.

Returns:

the created node.

childrenIterator

public RowIterator childrenIterator(int node)

Description copied from interface: Tree

Returns the iterator over the children of a node.

Specified by:

childrenIterator in interface Tree

Parameters:

node - the node

Returns:

the iterator over the children of the node

getChild

public int getChild(int node,
                    int index)

Description copied from interface: Tree

Returns the nth child of a node.

Specified by:

getChild in interface Tree

Parameters:

node - the node

index - the index if the requested child

Returns:

the requested child or NIL if node has not so many children.

getChildCount

public int getChildCount(int node)

Description copied from interface: Tree

Returns the number of children of a node.

Specified by:

getChildCount in interface Tree

Parameters:

node - the node.

Returns:

the number of children of a node.

getDepth

public int getDepth(int node)

Description copied from interface: Tree

Returns the depth of a node using either a depth column if it has been computed or the computeDepth method.

Specified by:

getDepth in interface Tree

Parameters:

node - the node.

Returns:

the depth of the node.

getParent

public int getParent(int node)

Description copied from interface: Tree

Returns the parent of a node.

Specified by:

getParent in interface Tree

Parameters:

node - the node

Returns:

the parent or the NIL value if node is the top node

isAncestor

public boolean isAncestor(int node,
                          int par)

Description copied from interface: Tree

Returns true if the first node has the second node as ancestor.

Specified by:

isAncestor in interface Tree

Parameters:

node - the node.

par - the tested ancestor.

Returns:

true if the first node has the second node as ancestor.

isLeaf

public boolean isLeaf(int node)

Description copied from interface: Tree

Returns true if the node is a leaf_node. Use this method rather than degree(node)==0

Specified by:

isLeaf in interface Tree

Parameters:

node - the node

Returns:

true if the node is a leaf_node.

nextNode

public int nextNode()

Description copied from interface: Tree

Returns the next node to be returned by addNode.

Specified by:

nextNode in interface Tree

Returns:

the next node to be returned by addNode.

reparent

public void reparent(int node,
                     int newparent)

Description copied from interface: Tree

Change the parent of a specified node, changing the structure.

Specified by:

reparent in interface Tree

Parameters:

node - the node.

newparent - the new parent.

removeNode

public boolean removeNode(int node)

Description copied from interface: Tree

Removes a node from the tree.

Specified by:

removeNode in interface Tree

Parameters:

node - the node to remove

Returns:

true if the node has been removed.

getNodeCount

public int getNodeCount()

Description copied from interface: Tree

Returns the number of proper nodes in the Tree. Can be different than the value returned by getRowCount if nodes have been removed.

Specified by:

getNodeCount in interface Tree

Returns:

the number of proper nodes in the Tree.
