org.sleuthkit.autopsy.timeline.events.FilteredEventsModel

This class acts as the model for a {@link TimeLineView}Views can register listeners on properties returned by methods. This class is implemented as a filtered view into an underlying {@link EventsRepository}. TODO: as many methods as possible should cache their results so as to avoid unnecessary db calls through the {@link EventsRepository} -jmConcurrency Policy: repo is internally synchronized, so methods that only access the repo atomicaly do not need further synchronization all other member state variables should only be accessed with intrinsic lock of containing FilteredEventsModel held. Many methods delegate to a task submitted to the dbQueryThread executor. These methods should synchronize on this object, and the tasks should too. Since the tasks execute asynchronously from the invoking methods, the methods will return and release the lock for the tasks to obtain.
