Class ActivityList

com.storedobject.chart.ActivityList

public class ActivityList
extends AbstractProject

Class to represent a list of activities (instances of ActivityList.Activity).

ActivityChart uses data from this class.

An ActivityList consists of instances of ActivityList.Activity and each ActivityList.Activity belongs to an ActivityList.ActivityGroup. Instances of ActivityList.Activity can be created via createActivity(ActivityGroup, String, LocalDateTime, int) or createActivity(ActivityGroup, String, LocalDateTime, LocalDateTime). Alternatively, a ActivityList.Activity can be created under an ActivityList.ActivityGroup via ActivityList.ActivityGroup.createActivity(String, LocalDateTime, int) or createActivity(ActivityGroup, String, LocalDateTime, LocalDateTime).

Constructor Details

ActivityList

public ActivityList()

Constructor for a date-based event list.

ActivityList

public ActivityList(ChronoUnit durationType)

Constructor.

Parameters:

durationType - Type of duration to be used for this ActivityList. (Note: ChronoUnit.ERAS and ChronoUnit.FOREVER are not supported and if used, will be considered as ChronoUnit.MILLIS).

Method Details

isEmpty

public boolean isEmpty()

createActivityGroup

public ActivityList.ActivityGroup createActivityGroup(String name)

Create and add a ActivityList.ActivityGroup to the ActivityList.

Parameters:

name - Name of the activity group.

Returns:

Activity group created.

createActivity

public ActivityList.Activity createActivity(ActivityList.ActivityGroup activityGroup,
 String activityName,
 LocalDateTime start,
 int duration)

Create and add a ActivityList.Activity to the ActivityList.

Parameters:

activityGroup - Group to which the ActivityList.Activity to be added.

activityName - Name of the ActivityList.Activity.

start - Start.

duration - Duration of the ActivityList.Activity. (Should be grater than 0).

Returns:

Activity created. (Returns null if the ActivityList.ActivityGroup passed doesn't belong to this).

createActivity

public ActivityList.Activity createActivity(ActivityList.ActivityGroup activityGroup,
 String activityName,
 LocalDateTime start,
 LocalDateTime end)

Create and add a ActivityList.Activity to the ActivityList.

Parameters:

activityGroup - Group to which the ActivityList.Activity to be added.

activityName - Name of the ActivityList.Activity.

start - Start.

end - End.

Returns:

Activity created. (Returns null if the ActivityList.ActivityGroup passed doesn't belong to this).

delete

public void delete(ActivityList.ActivityGroup... activityGroups)

Delete ActivityList.ActivityGroups from the ActivityList. (All ActivityList.Activitys and dependencies related to these groups will be dropped).

Parameters:

activityGroups - ActivityList.ActivityGroups to delete.

delete

public void delete(ActivityList.Activity... activities)

Delete ActivityList.Activitys from the ActivityList. (All dependencies related to these activities will be dropped).

Parameters:

activities - ActivityList.Activitys to delete.

setStart

public final void setStart(LocalDateTime start)

Description copied from class: AbstractProject

Set the start of the project. Depending on the duration type, one of the "setStart" methods can be used. However, the start value will be appropriately trimmed if you try to set a higher resolution value.

Overrides:

setStart in class AbstractProject

Parameters:

start - Start of the project.

getStart

public final LocalDateTime getStart()

Description copied from class: AbstractProject

Get the project start.

Overrides:

getStart in class AbstractProject

Returns:

Start date/time.

Returns:

End date/time.

getRowCount

public final int getRowCount()

getEventGroup

public final ActivityList.ActivityGroup getEventGroup(int groupIndex)

Returns:

ActivityList.ActivityGroup.

getGroupCount

public final int getGroupCount()

Get the number of ActivityList.Activity belonging to this group.

Returns:

Activity count.

streamGroups

public Stream<ActivityList.ActivityGroup> streamGroups()

Get all activity groups of this ActivityList.

Note: Null will be returned if the ActivityList contains inconsistencies.

Returns:
