Method Detail

addNode

public Node addNode(Coordinate coord)

This method expects that a node has a coordinate value.

Parameters:

coord - Coordinate

Returns:

node for the provided coord

addNode

add

public void add(EdgeEnd e)

Adds a node for the start point of this EdgeEnd (if one does not already exist in this map). Adds the EdgeEnd to the (possibly new) node.

Parameters:

e - EdgeEnd

find

Find coordinate.

Parameters:

coord - Coordinate to find

Returns:

the node if found; null otherwise

iterator

public Iterator iterator()

values

public Collection values()

getBoundaryNodes

public Collection getBoundaryNodes(int geomIndex)

print
