Constructor Detail

LinkManhattanConnector

public LinkManhattanConnector(Site tail,
                              Site head,
                              Link link)

Construct a new connector with the given tail and head for the specified link. The head and tail sites may be representative sites for multiport, in which case they are not necessarily the ones returned by getHeadSite() or getTailSite(). Those methods will return new sites as needed to ensure that each each connection is to its own site.

Parameters:

tail - The tail site.

head - The head site.

link - The link.

Specified by:

getHeadSite in interface Connector

Overrides:

getHeadSite in class AbstractConnector

Returns:

The connection site.

getLink

public Link getLink()

Return the associated link.

Returns:

The associated link.

getTailSite

public Site getTailSite()

Override the base class to return a different site for each connection to a multiport.
