Interface IterableTreeNode<O>

All Superinterfaces:

Iterable<IterableTreeNode<?>>, TreeNode

All Known Implementing Classes:

DefaultIterableTreeNode

public interface IterableTreeNode<O>
extends TreeNode, Iterable<IterableTreeNode<?>>

A TreeNode implementation that is mutable, but does not implements MutableTreeNode, because this API has some lacks:

• Implementation use Vector
• Methods around userObject are not typed

Moreover this class implements Iterable to get nice access to children nodes using modern API. In that way we can perform nice and efficient traversal algorithms using exclusively Stream API.

stream

default Stream<IterableTreeNode<?>> stream()

isRoot

boolean isRoot()

getRoot

IterableTreeNode<?> getRoot()

getParent

IterableTreeNode<?> getParent()

Specified by:

getParent in interface TreeNode

setParent

void setParent(IterableTreeNode<?> parent)

setAllowsChildren

void setAllowsChildren(boolean allowsChildren)

isEmpty

boolean isEmpty()

getUserObject

O getUserObject()

setUserObject

void setUserObject(O userObject)

addChild

void addChild(IterableTreeNode<?> newChild)

insertChild

void insertChild(IterableTreeNode<?> newChild,
                 int position)

removeChild

void removeChild(int index)

Remove child at given index.

Will throw exception if no child at index.

Parameters:

index - position of child to remove

removeChild

void removeChild(IterableTreeNode<?> child)

Remove given given child.

Will throw exception if given child is not a child of this node.

Parameters:

child - child to remove

removeChildren

void removeChildren()

Removes all of this node's children, setting their parents to null. If this node has no children, this method does nothing.

removeChildren

void removeChildren(List<IterableTreeNode<?>> children)

Remove given children. Acts as method removeChild(IterableTreeNode) for each element.

Parameters:

children - children to remove

preorderIterator

default Iterator<IterableTreeNode<?>> preorderIterator()

postorderIterator

default Iterator<IterableTreeNode<?>> postorderIterator()

breadthFirstIterator

default Iterator<IterableTreeNode<?>> breadthFirstIterator()
