Interface IRelationship<T>

Type Parameters:

T - the object type of the timeline objects

All Known Implementing Classes:

DefaultRelationship

public interface IRelationship<T>

Timeline objects may have some kind of relationship between each other. To visualize this relationship (which might be a dependency / constraint like "finish before start") lines with arrows can be drawn between them. To enable the user interface to draw these lines a relationship object needs to return the related timeline objects plus the tree paths to locate the row on which they are displayed. The path and the timeline object information is encapsulated in instances of type TimelineObjectPath.
