link.router()
Return a shallow copy of the router
property of the link.
For backwards compatibility, if there is no router, the function also checks whether the legacy manhattan
property is set on the link and returns { name: orthogonal }
if it is.
link.router(router [, opt])
Set the router
of the link.
If the router
argument is an object, it is expected to have the form { name: routerName, args?: routerArgs }
. Here routerName
is expected to match either the name of a built-in router or the name of a custom router.
If the router
argument is a function, it is expected to define a custom router with the signature function(vertices, routerArgs, linkView)
that returns an array of route points.
link.router(routerName [, routerArgs, opt])
Set the router
of the link to have the value { name: routerName, args: routerArgs }
.
The routerName
string is expected to match either the name of a built-in router or the name of a custom router. The routerArgs
parameter is optional.
