        +--org.eclipse.draw2d.AutomaticRouter

All Implemented Interfaces:

ConnectionRouter

Direct Known Subclasses:

FanRouter

public abstract class AutomaticRouter

extends AbstractRouter

The AutomaticRouter provides the facility to prevent Connections from overlapping. Subclasses implement the abstract method handleCollision(PointList list, int index) to determine how to handle Connection collisions. Also provides access to its 'next' router so that manual routing in subclasses is possible.
