IlvGanttConfiguration (Rogue Wave JViews 9.2 API)

java.lang.Object
- ilog.views.gantt.IlvGanttConfiguration

```
public class IlvGanttConfiguration
extends Object
```
IlvGanttConfiguration is the central facade for a coordinated set of Gantt UIs that display information from the same data model. IlvGanttConfiguration is also a central location for interested listeners to subscribe to any event in the Gantt system.
In addition to providing centralized routing and distribution of events published by the various components that make up the Gantt system, IlvGanttConfiguration is responsible for firing the following events:
- A GanttModelChanged event is fired as an aboutToChange event when the data model is about to be replaced and is fired again as a changed event once the data model has been replaced.

    Returns the first visible row of the tree or null if no rows are visible. The type of the returned row will match the row organization of this configuration. In other words, if getRowType is ACTIVITY_ROWS, then the returned row will be an IlvActivity. If getRowType is RESOURCE_ROWS, then the returned row will be an IlvResource.

```
public IlvHierarchyNode getFirstVisibleRow()
```
    Returns the first visible row in the tree or null if no rows are visible. If the data model contains at least a root row and the root row is set visible, this method will return the root row. If the root row is set not visible, this method will return the first child of the root row, if it exists in the data model. The type of the returned row will match the row organization of this configuration. That is, if getRowType returns ACTIVITY_ROWS, then the returned row will be an IlvActivity. If getRowType is RESOURCE_ROWS, then the returned row will be an IlvResource. This method is equivalent to calling getRow(0).

    Sets whether the root row of the tree is visible, or whether the children of the root row should be the highest level visible rows. The root row will be expanded if necessary before it is hidden. This is done to ensure that the children of the root row are visible. While the root row is hidden, it is inhibited from being collapsed.
    
    Parameters:
    
    rootVisible - Set to true to make the root row of the tree visible. Set to false to make the children of the root row the highest level visible rows.

  - getReservationCacheLoadThreshold
```
public float getReservationCacheLoadThreshold()
```
    Returns the threshold that will trigger the reservation cache's time interval to be expanded. When this interval expands, the cache queries the Gantt data model for reservations that fall within the new interval. The threshold is expressed as a fraction of the configuration's current visible duration. Higher values mean that the reservation cache will query the data model more frequently. A value of 0 means that the data model will not be queried until the visible interval is scrolled to the current limits of the cache. The default value is 0.25.
    For example, let us assume that the reservation cache has a time interval from May 1 to May 20, a duration of 20 days, the current visible interval is 8 days, and the reservationCacheLoadThreshold is 0.25. The reservation cache's time interval will be expanded, and therefore new reservations will be loaded from the data model, when the visible interval is scrolled to be within 2 days (0.25 * 8) of May 1 or May 20.
```

   threshold                        threshold

  - setReservationCacheLoadThreshold
```
public void setReservationCacheLoadThreshold(float loadThreshold)
```
    Sets the threshold that will trigger the reservation cache's time interval to be expanded. When this interval expands, the cache queries the Gantt data model for reservations that fall within the new interval. The threshold is expressed as a fraction of the configuration's current visible duration and must be >=0. Higher values mean that the reservation cache will query the data model more frequently. A value of 0 means that the data model will not be queried until the visible interval is scrolled to the current limits of the cache. You should not set a threshold that is larger than the reservationCacheLoadFactor because the cache will still exceed the threshold after its interval is expanded.
    For example, assume that the reservation cache has a time interval from May 1 to May 20, a duration of 20 days, the current visible interval is 8 days, and the reservationCacheLoadThreshold is 0.25. The reservation cache's time interval will be expanded, and therefore new reservations will be loaded from the data model, when the visible interval is scrolled to be within 2 days (0.25 * 8) of May 1 or May 20.

  - getReservationCacheLoadFactor
```
public float getReservationCacheLoadFactor()
```
    Returns the factor by which the reservation cache's time interval is expanded. This is expressed as a multiple of the configuration's current visible duration. Both the cache start time and end time are expanded by the same amount. Therefore, the cache's interval is actually expanded by twice this value. The default value is 1.5.
    For example, assume that the configuration has a visible duration of 10 days, has just been scrolled to the visible interval of June 1 to June 10, and the reservationCacheLoadThreshold has just been triggered. If the loadFactor is 0, the cache will be expanded to include exactly the June 1 - June 10 interval. If the loadFactor is 0.1, the cache will be expanded to include the interval May 31 - June 11, which is 1 day longer (0.1 * 10) at both ends than the visible interval.
    
    Returns:
    
    The reservation cache load factor, as a multiple of the current visible duration.
