Method Detail

parent

Node parent()

Return the Node that contains (and created) this Node.

id

int id()

Return the unique ID of this node. This starts at 1 and is incremented for each new Node that is created.

parent

void parent(Node node)

Set the parent to a new value. Should only be called inside NodeBase.

getAncestor

<T extends Node> T getAncestor(Class<T> type)

Return the first ancestor of this node of the given type, if any. Throws IllegalArgumentException if not found.

copy

<T extends Node> T copy(Class<T> cls)

Make a deep copy of this node. If nn = n.copy(), then n.parent() == nn.parent(), which also means that the parent is NOT copied.

copy

<T extends Node> T copy(Node newParent,
                        Class<T> cls)

Copy setting a new parent in the result.

accept

void accept(Visitor visitor)

Accept the visitor and allow it to perform actions on this Node.
