Method Detail

getParent

public Node<T> getParent()

findParent

public Node<T> findParent(NodePredicate<T> predicate)

Finds the parent which satisfies the predicate. Starts with the parent of this node not the node itself.

Parameters:

predicate -

Returns:

collectParents

public List<Node<T>> collectParents(NodePredicate<T> predicate)

getChildren

public List<Node<T>> getChildren()

Return the children of Node. The Tree is represented by a single root Node whose children are represented by a List>. Each of these Node elements in the List can have children. The getChildren() method will return the children of a Node.

Returns:

the children of Node

getNumberOfChildren

public int getNumberOfChildren()

Returns the number of immediate children of this Node.

Returns:

the number of immediate children.

addChild

public Node<T> addChild(T data)

addChild

public Node<T> addChild(Node<T> child)

Adds a child to the list of children for this Node. The addition of the first child will create a new List>.

Parameters:

child - a Node object to set.

insertChildAt

public void insertChildAt(int index,
                 Node<T> child)
                   throws IndexOutOfBoundsException

Inserts a Node at the specified position in the child list. Will * throw an ArrayIndexOutOfBoundsException if the index does not exist.

Parameters:

index - the position to insert at.

child - the Node object to insert.

Throws:

IndexOutOfBoundsException - if thrown.

removeChild

public boolean removeChild(Node<T> child)

removeChildAt

public void removeChildAt(int index)
                   throws IndexOutOfBoundsException

Remove the Node element at index index of the List>.

Parameters:

index - the index of the element to delete.

Throws:

IndexOutOfBoundsException - if thrown.

getData

public T getData()

setData

public void setData(T data)

toString

public String toString()

Overrides:

toString in class Object
