Window sorting by values in the specified field extending a specified number of elements from the lowest value up or the highest value down. The view accepts 3 parameters. The first parameter is the field name to get the values to sort for, the second parameter defines whether to sort ascending or descending, the third parameter is the number of elements to keep in the sorted list. The type of the field to be sorted in the event must implement the Comparable interface. The natural order in which events arrived is used as the second sorting criteria. Thus should events arrive with equal sort values the oldest event leaves the sort window first. Old values removed from a prior view are removed from the sort view.

The following tables list the members exposed by the SortWindowView type.

Public Methods

  NameDescription
AddView
Add a view to the viewable object.
(Inherited from ViewSupport.)
AttachesTo
Return null if the view will accept being attached to a particular object.
(Overrides .AttachesTo(Viewable).)
Equals (Inherited from Object.)
GetEnumerator
Returns an enumerator that iterates through the collection.
(Overrides .GetEnumerator().)
GetHashCode (Inherited from Object.)
GetType (Inherited from Object.)
GetViews
Returns all added views.
(Inherited from ViewSupport.)
RemoveView
Remove a view.
(Inherited from ViewSupport.)
ToString
Returns a String that represents the current Object.
(Overrides .ToString().)
Update
Notify that data has been added or removed from the Viewable parent. The last object in the newData array of objects would be the newest object added to the parent view. The first object of the oldData array of objects would be the oldest object removed from the parent view.

If the call to update contains new (inserted) data, then the first argument will be a non-empty list and the second will be empty. Similarly, if the call is a notification of deleted data, then the first argument will be empty and the second will be non-empty. Either the newData or oldData will be non-null. This method won't be called with both arguments being null, but either one could be null. The same is true for zero-length arrays. Either newData or oldData will be non-empty. If both are non-empty, then the update is a modification notification.

When update() is called on a view by the parent object, the data in newData will be in the collection of the parent, and its data structures will be arranged to reflect that. The data in oldData will not be in the parent's data structures, and any access to the parent will indicate that that data is no longer there.

(Overrides .Update(EventBean[](), EventBean[]()).)
