Methods in pqrtree that return Node

Node	Node.findLeader() Finds the representative of the disjoint set, implementing the shrink path heuristics
Node	Node.getAncestorReference() Gets the ancestor reference link, if it exists.
Node	Node.union(Node v, int sizeV, Node p, int sizeP) Join two node children of the same node.

Methods in pqrtree with parameters of type Node

void	PQRNode.addBlackChild(Node child) Adds a child node to the end of the black children's list.
void	PQRNode.addChild(Node child) Adds a node to the end of the children's list.
void	PQRNode.addGrayChild(Node child) Adds a child node to the end of the gray children's list.
private java.lang.String	PQRTree.frontier(Node v) Creates a string representing a valid permutation recursively.
private java.lang.String	PQRTree.preOrder(Node v) Creates a string representing the tree recursively.
void	Node.setAncestorReference(Node n) Sets the ancestor direct link.
Node	Node.union(Node v, int sizeV, Node p, int sizeP) Join two node children of the same node.
