Interface HierarchicalTimeBarModel

All Known Implementing Classes:

DefaultHierarchicalTimeBarModel

public interface HierarchicalTimeBarModel

Interface describing a hierarchical model. As of version 0.96 this is not an extension of the TimeBarModel since the extraction of the view state (expanded state) in the hierarchy did imply a stricter separation. Care should be taken if nodes should appear in several positions in the node. There is no restriction on this by the model itself. However the ViewState will not distinguish the state of equal nodes in different positions resulting in the same expanded state of all equal nodes.
