This function removes "this" Arc from all connected Nodes.

addToNodes

public void addToNodes()

This function adds this Arc to all connected Nodes.

getBendPoints

public java.util.Vector getBendPoints()

Returns a Vector of bend points.

getSource

public Node getSource()

Returns the source node of this connection.

setSource

public void setSource(Node source_node)
