addChild

removeChild

public void removeChild(SimpleTreeNode<V> child)

getChildren

public List<SimpleTreeNode<V>> getChildren()

Description copied from interface: TreeNode

Returns the children of the tree node.

In order to keep the tree structure consistent, implementations of this interface must implement the following behavior:

• A child can only be added if the child is a suitable child for this node, and this node is a suitable parent for the child. See TreeNode.isSuitableChild(TreeNode), TreeNode.isSuitableParent(TreeNode).
• If a child is added to this list, then this tree node removes it from its former parent, and this tree node then sets itself as the parent of the* child.
• If a child is removed from this tree node, then this tree node sets the parent of the child to null.

Specified by:

getChildren in interface TreeNode<V>

Returns:

the children

getParent

public @Nullable SimpleTreeNode<V> getParent()

Description copied from interface: TreeNode

Returns the parent of the tree node.

Note that - by convention - the parent property is changed only by a parent tree node.

Specified by:

getParent in interface TreeNode<V>

Returns:

the parent. Returns null if the tree node has no parent.

setParent

public void setParent(@Nullable SimpleTreeNode<V> newValue)

Description copied from interface: TreeNode

Sets the parent of the tree.

Note that - by convention - the parent property is changed only by a parent tree node.

Specified by:

setParent in interface TreeNode<V>

Parameters:

newValue - the new parent

getValue

public V getValue()

setValue

public void setValue(V value)
