IlvGanttModel (Rogue Wave JViews 9.1 API)

All Known Implementing Classes:

IlvAbstractGanttModel, IlvBasicFilterGanttModel, IlvDefaultGanttModel, IlvFilterGanttModel, IlvJDBCGanttModel, IlvTableGanttModel
```
public interface IlvGanttModel
```
IlvGanttModel defines the abstract behavior of the Gantt's data model. Any object that implements this interface can be displayed by the Gantt library. IlvGanttModel defines basic accessors for manipulating and querying the data model, as well as the events by which the data model will notify interested listeners about any changes.
An IlvGanttModel is responsible for managing 4 types of entities:
- A hierarchical tree structure of IlvActivity's. The root of the tree can be accessed via getRootActivity().
- A hierarchical tree structure of IlvResource's. The root of the tree can be accessed via getRootResource().
- An unordered collection of all of the resource-to-activity IlvReservation's.
- An unordered collection of all of the activity-to-activity IlvConstraint's.
Each of these entity types routes event notification to interested listeners through the Gantt data model. They do not handle listener subscriptions directly. For each type of entity, there are essentially 2 types of event notifications. First are events indicating a change in a property or other characteristic of a specific entity instance. Second are events that indicate that an entity instance has been added to the data model, removed from the data model, or some other aspect of its membership in the data model has changed. For IlvActivity's and IlvResource's, separate listener interfaces are used for receiving notification of property changes (ActivityListener and ResourceListener) and data model membership changes (ActivityHierarchyListener and ResourceHierarchyListener). IlvReservation and IlvConstraint each use a single listener interface for all of their events, ReservationListener and ConstraintListener respectively.

- Field Detail
  - ADJUSTING_PROPERTY
```
static final String ADJUSTING_PROPERTY
```
    Identifies that an adjustment session has begun or ended.
    An adjustment session encompasses a user action or interaction, often comprising several mouse events and possibly extending over several seconds of time. For example, when user drags objects in a Gantt sheet, the entire interaction from the mouse-pressed event to the mouse-released event later will be in a single adjustment session.
    Adjustment sessions can contain batching sessions. Batching sessions are shorter than adjustment sessions: A batching session does not last longer than the reaction on a single mouse event.

  - BATCHING_PROPERTY
```
static final String BATCHING_PROPERTY
```
    Identifies that a batching session has begun or ended.
    A batching session is meant to group together modifications to multiple activities, resources, constraints, or reservations, that occur immediately one after the other and that all arise from a single input event or from a single API call.
    Batching sessions may be contained in adjustment sessions.
    When an IlvGanttSheet is connected to this model, a batching session on this model automatically translates into an IlvGanttSheet.beginRedrawSession(boolean)/IlvGanttSheet.endRedrawSession() pair of calls on that Gantt sheet, which implies an IlvManager.initReDraws()/IlvManager.reDrawViews() pair of calls on its grapher, and a pair of {#link setContentsAdjusting(true/false) calls on that grapher.

    Removes the child activity from parent that is at the specified location in its list of child activities. Any subsequent child activities are shifted to the left by having their indices decremented. All constraints and reservations associated with the child activity and its children are also removed from the data model. After the activity has been removed, the data model will first fire ConstraintRemovedEvents and ReservationRemovedEvents for each removed constraint and reservation. The removingActivity property of these events will be true. Then, the data model will fire an ActivitiesRemovedEvent.
    
    Parameters:
    
    parent - The parent activity from which to remove the child activity. The implementation of this method should use IlvGanttModelUtil.checkValidMemberActivity(ilog.views.gantt.IlvActivity, ilog.views.gantt.IlvGanttModel) to validate parent.
    
    index - The location within parent's list of children to remove the child activity.
    
    Throws:
    
    IllegalArgumentException - if parent is null or is not a member of this data model.
    
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= getChildActivityCount(parent)).

  - removeActivity
```
void removeActivity(IlvActivity activity)
```
    Removes the specified child activity from its parent. All constraints and reservations associated with the activity and its children are also removed from the data model. After the activity has been removed, the data model will first fire ConstraintRemovedEvents and ReservationRemovedEvents for each removed constraint and reservation. The removingActivity property of these events will be true. Then, the data model will fire an ActivitiesRemovedEvent. This method cannot be used to remove the data model's root activity. Use setRootActivity(null) for that purpose.
    
    Parameters:
    
    activity - The activity to remove. It must be a member of this data model, but cannot be the root activity. The implementation of this method should use IlvGanttModelUtil.checkValidNonRootMemberActivity(ilog.views.gantt.IlvActivity, ilog.views.gantt.IlvGanttModel) to validate activity before removing it.
    
    Throws:
    
    IllegalArgumentException - if activity is null, is not a member of this data model, or is the root activity.

    An iterator over all the reservations in the data model that are associated with the specified resource and where the assigned activity intersects the specified time interval, in no particular order.
  - addReservation
```
void addReservation(IlvReservation newReservation)
```
    Adds newReservation to the data model. The reservation's resource and activity must already be members of this data model. After the reservation has been added, the data model will fire a ReservationInsertedEvent.
    The implementation of this method can use IlvGanttModelUtil.checkValidNewReservation() to validate newReservation.
    
    Parameters:
    
    newReservation - The reservation to add.
    
    Throws:
    
    IllegalArgumentException - if newReservation is null, is a member of a data model already, its resource is is not a member of this data model, or its activity is not a member of this data model.

  - removeReservation
```
void removeReservation(IlvReservation reservation)
```
    Removes the specified reservation from the data model. After the reservation has been removed, the data model will fire a ReservationRemovedEvent.
    The implementation of this method can use IlvGanttModelUtil.checkValidMemberReservation() to validate reservation before removing it.
    
    Parameters:
    
    reservation - The reservation to remove.
    
    Throws:
    
    IllegalArgumentException - if reservation is null or is not a member of this data model

    ReservationRemovedEvent, ReservationListener.reservationChanged(ilog.views.gantt.event.ReservationEvent), IlvGanttModelUtil.checkValidMemberReservation(ilog.views.gantt.IlvReservation, ilog.views.gantt.IlvGanttModel)
  - addReservationListener
```
void addReservationListener(ReservationListener aListener)
```
    Adds the specified listener to receive reservation events from this data model.
    
    Parameters:
    
    aListener - The listener which will be subscribed to subsequent ReservationListener events.
  - removeReservationListener
```
void removeReservationListener(ReservationListener aListener)
```
    Removes the specified listener so that it no longer receives reservation events from this data model.
    
    Parameters:
    
    aListener - The listener which will be unsubscribed from receiving ReservationListener events.
  - fireReservationEvent
```
void fireReservationEvent(ReservationEvent event)
```
    Fire a reservation event to all subscribed listeners.
    Warning: This method is considered to be part of an IlvGanttModel's internal implementation and not a public API. You should only invoke this method directly if you have created your own IlvReservation implementation that does not subclass IlvAbstractReservation.
    
    Parameters:
    
    event - The reservation event.
