public class FigForeignKey

extends org.tigris.gef.presentation.FigEdge

implements java.awt.event.MouseListener, ErjConstants

A Fig that paints edges between ports. This version automatically routes a rectilinear edge. The routing is not very good. It avoids the source and sink nodes and no other nodes. It is basically case-analysis, and some of the cases are wrong or missing. Anyway, the user can edit the edge by dragging handles. The 0th and last handles are fixed in position so that they stay connected to ports. If the user drags a handle next to a fixed handle, a new vertex is automatically inserted.

FigForeignKey

public FigForeignKey(org.tigris.gef.presentation.Fig srcPort,
                     org.tigris.gef.presentation.Fig dstPort,
                     org.tigris.gef.presentation.FigNode srcNode,

                     java.lang.Object edge)

Method Detail

makeEdgeFig

protected org.tigris.gef.presentation.Fig makeEdgeFig()

Instanciate a FigRectilinear.

Specified by:

makeEdgeFig in class org.tigris.gef.presentation.FigEdge

computeRoute

public void computeRoute()

Find the route that the edge should follow. Basically case analysis to route around source and destination nodes. Needs-More-Work: A better algorithm would really be useful. Needs-More-Work: Sometimes the edge can get non-rectilinear.

Overrides:

computeRoute in class org.tigris.gef.presentation.FigEdge

layoutEdge

protected void layoutEdge()

Internal function to actually compute the layout of the line if it has never been done on that line before.
