Method Detail

getHeadSite

Site getHeadSite()

Get the site that marks the "head" of the connector.

getTailSite

Site getTailSite()

Get the site that marks the "tail" of the connector.

headMoved

void headMoved(double dx,
               double dy)

Inform the connector that the head site has moved. The connector is expected to reroute itself using an efficient means as is available. Repaint the figure.

reroute

void reroute()

Tell the connector to re-route itself. In general, implementations of this method should be more efficient than route(). Repaint the figure.

route

void route()

Tell the connector to route itself completely, using all available information. Repaint the figure.

setHeadSite

void setHeadSite(Site s)

Set the site that marks the "head" of the connector.

setTailSite

void setTailSite(Site s)

Set the site that marks the "tail" of the connector.

tailMoved

void tailMoved(double dx,
               double dy)

Inform the connector that the tail site has moved. The connector is expected to reroute itself using an efficient means as is available. Repaint the figure.
