  • Method Details

    • getChildren

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

    • getParent

      public Node<T> getParent()

    • setChildren

      public void setChildren(List<Node<T>> children)
      Sets the children of a Node<T> object. See docs for getChildren() for more information.
      Parameters:
      children - the List<Node<T>> to set.

    • getNumberOfChildren

      public int getNumberOfChildren()
      Returns the number of immediate children of this Node<T>.
      Returns:
      the number of immediate children.

    • addChild

      public void addChild(Node<T> child)
      Adds a child to the list of children for this Node<T>. The addition of the first child will create a new List<Node<T>>.
      Parameters:
      child - a Node<T> object to set.

    • insertChildAt

      public void insertChildAt(int index, Node<T> child) throws IndexOutOfBoundsException
      Inserts a Node<T> 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<T> object to insert.
      Throws:
      IndexOutOfBoundsException - if thrown.

    • removeChildAt

      public void removeChildAt(int index) throws IndexOutOfBoundsException
      Remove the Node<T> element at index index of the List<Node<T>>.
