Method Detail

add

public void add(EdgeEnd e)

addNode

public Node addNode(Node n)

addNode

public Node addNode(Point coord)

This method expects that a node has a coordinate value.

find

public Node find(Point coord)

Returns:

the node if found; null otherwise

getBoundaryNodes

public Collection<Node> getBoundaryNodes(int geomIndex)

iterator

public Iterator<Node> iterator()

Specified by:

iterator in interface Iterable<Node>

print

public void print(PrintStream out)

values

public Collection<Node> values()
