Examples of org.tinyuml.draw.Connection

org.tinyuml.draw.Connection
This class implements a visual binary connection between to Node elements. The current implementation tries to implement any kind of line connection, the visual representation is dependent on the embedded model element and a number of view parameters. @author Wei-ju Wu @version 1.0
