Class ActivityLink<A extends Activity>

java.lang.Object

com.flexganttfx.model.ActivityLink<A>

Type Parameters:

A - the type of the two activities being linked together

public class ActivityLink<A extends Activity>
extends Object

An activity link can be used to model any kind of dependency between two activities. In project planning applications a link would express a predecessor / successor relationship between two tasks, for example "task A must be finished before task B can begin". In other domains a link might simply express that two or more activities need to be scheduled together and that moving one of them requires all others to be moved, too.
