public class TimelineEntity
extends Object
implements Comparable<TimelineEntity>

The class that contains the the meta information of some conceptual entity and its related events. The entity can be an application, an application attempt, a container or whatever the user-defined object.

Primary filters will be used to index the entities in TimelineStore, such that users should carefully choose the information they want to store as the primary filters. The remaining can be stored as other information.
