Method Detail

addActivity

public final void addActivity(ActivityRef<A> activityRef)

removeActivity

public final void removeActivity(ActivityRef<A> activityRef)

clearActivities

public final void clearActivities()

clearActivities

public final void clearActivities(Layer layer)

getEarliestTimeUsed

public final Instant getEarliestTimeUsed()

Description copied from interface: ActivityRepository

Returns the earliest time used by the activities stored in this repository / on this row. This method gets used for navigation (e.g. "scroll to earliest time used in the Gantt chart", "zoom out to show all activities").

Specified by:

getEarliestTimeUsed in interface ActivityRepository<A extends Activity>

Overrides:

getEarliestTimeUsed in class ActivityRepositoryBase<A extends Activity>

Returns:

the earliest time used by the activities in this repository / row (null if no activities found)

getLatestTimeUsed

public final Instant getLatestTimeUsed()

Description copied from interface: ActivityRepository

Returns the latest time used by the activities stored in this repository / on this row. This method gets used for navigation (e.g. "scroll to latest time used in the Gantt chart", "zoom out to show all activities").

Specified by:

getLatestTimeUsed in interface ActivityRepository<A extends Activity>

Overrides:

getLatestTimeUsed in class ActivityRepositoryBase<A extends Activity>

Returns:

the latest time used by the activities in this repository / row (null if no activities found)

getActivities

public final Iterator<A> getActivities(Layer layer,
                                       Instant startTime,
                                       Instant endTime,
                                       TemporalUnit temporalUnit,
                                       ZoneId zoneId)

Description copied from interface: ActivityRepository

Returns an iterator for iterating over all activities found for the given layer and time interval. This method has to return very fast as it gets called many times during rendering of the chart. A slow implementation will have a direct impact on scrolling / rendering performance.

Parameters:

layer - the layer for which to return the activities

startTime - the start time of the time interval for which to return the activities

endTime - the end time of the time interval for which to return the activities

temporalUnit - the temporal unit currently displayed in the dateline

zoneId - the timezone currently displayed in the dateline

Returns:

the activities on the given layer and in the given time interval

getAllActivities

public final List<A> getAllActivities()
