public function HierarchicalCollectionViewCursor(collection:HierarchicalCollectionView, model:ICollectionView, hierarchicalData:IHierarchicalData)| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Constructor.
Parametrelercollection:HierarchicalCollectionView — The HierarchicalCollectionView instance referenced by this cursor.
| |
model:ICollectionView — The source data collection.
| |
hierarchicalData:IHierarchicalData — The data used to create the HierarchicalCollectionView instance.
|
findAny | () | yöntem |
public function findAny(values:Object):Boolean| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Finds an item with the specified properties within the collection and positions the cursor to that item. If the item can not be found, the cursor location does not change.
The findAny() method can only be called on sorted views;
if the view isn't sorted, a CursorError is thrown.
If the associated collection is remote, and not all of the items have been cached locally, this method begins an asynchronous fetch from the remote collection. If one is already in progress, this method waits for it to complete before making another fetch request.
If multiple items can match the search criteria then the item found
is non-deterministic.
If it is important to find the first or last occurrence of an item
in a non-unique index, use the findFirst() or
findLast() method.
If the data is not local and an asynchronous operation must be performed, an ItemPendingError is thrown.
Parametreler
values:Object — The search criteria. The values in the Object must be configured as name-value pairs,
as in an associative array (or be the actual object to search for). The values of the names specified must match properties
specified in the sort. For example, if properties x, y, and
z are in the current sort, the values specified should be
{x: x-value, y: y-value, z: z-value}.
|
Boolean — When all of the data is local this method returns
true if the item can be found and false
otherwise.
|
findFirst | () | yöntem |
public function findFirst(values:Object):Boolean| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Finds the first item with the specified properties within the collection and positions the cursor to that item. If the item can not be found, no cursor location does not change.
The findFirst() method can only be called on sorted views;
if the view isn't sorted, a CursorError is thrown.
If the associated collection is remote, and not all of the items have been cached locally, this method begins an asynchronous fetch from the remote collection. If one is already in progress, this method waits for it to complete before making another fetch request.
If it is not important to find the first occurrence of an item
in a non-unique index, use findAny(), which may be
a little faster than the findFirst() method.
If the data is not local and an asynchronous operation must be performed, an ItemPendingError is thrown.

public function findLast(values:Object):Boolean| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Finds the last item with the specified properties within the collection and positions the cursor on that item. If the item can not be found, the cursor location does not chanage.
The findLast() method can only be called on sorted views;
if the view isn't sorted, a CursorError is thrown.
If the associated collection is remote, and not all of the items have been cached locally, this method begins an asynchronous fetch from the remote collection. If one is already in progress, this method waits for it to complete before making another fetch request.

insert | () | yöntem |
public function insert(item:Object):void| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Inserts the specified item before the cursor's current position.
If the cursor is afterLast,
the insertion occurs at the end of the view.
If the cursor is beforeFirst on a non-empty view,
an error is thrown.
Parametreler
item:Object — The item to insert before the cursor's current position.
|
moveNext | () | yöntem |
public function moveNext():Boolean| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Moves the cursor to the next item within the collection.
On success the current property is updated
to reference the object at this new location.
Returns true if the resulting current
property is valid, or false if not
(the property value is afterLast).
If the data is not local and an asynchronous operation must be performed, an ItemPendingError is thrown. See the ItemPendingError documentation and the collections documentation for more information on using the ItemPendingError.
DöndürürBoolean — true if still in the list,
false if the current value initially was
or now is afterLast.
|
movePrevious | () | yöntem |
public function movePrevious():Boolean| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Moves the cursor to the previous item within the collection.
On success the current property is updated
to reference the object at this new location.
Returns true if the resulting current
property is valid, or false if not
(the property value is beforeFirst).
If the data is not local and an asynchronous operation must be performed, an ItemPendingError is thrown. See the ItemPendingError documentation and the collections documentation for more information on using the ItemPendingError.
DöndürürBoolean — true if still in the list,
false if the current value initially was or
now is beforeFirst.
For example:
var myArrayCollection:ICollectionView = new ArrayCollection([ "Bobby", "Mark", "Trevor", "Jacey", "Tyler" ]);
var cursor:IViewCursor = myArrayCollection.createCursor();
cursor.seek(CursorBookmark.last);
while (!cursor.beforeFirst)
{
trace(current);
cursor.movePrevious();
}

remove | () | yöntem |
public function remove():Object| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Removes the current item and returns it.
If the cursor location is beforeFirst or
afterLast, throws a CursorError.
If you remove any item other than the last item,
the cursor moves to the next item. If you remove the last item, the
cursor is at the AFTER_LAST bookmark.
If the item after the removed item is not local and an asynchronous operation must be performed, an ItemPendingError is thrown. See the ItemPendingError documentation and the collections documentation for more information on using the ItemPendingError.
DöndürürObject — The item that was removed.
|
seek | () | yöntem |
public function seek(bookmark:CursorBookmark, offset:int = 0, prefetch:int = 0):void| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | Flash Player 9, AIR 1.1 |
Moves the cursor to a location at an offset from the specified
bookmark.
The offset can be negative, in which case the cursor is positioned
an offset number of items prior to the specified bookmark.
If the associated collection is remote, and not all of the items have been cached locally, this method begins an asynchronous fetch from the remote collection.
If the data is not local and an asynchronous operation must be performed, an ItemPendingError is thrown. See the ItemPendingError documentation and the collections documentation for more information on using the ItemPendingError.
Parametreler
bookmark:CursorBookmark — CursorBookmark reference to marker
information that allows repositioning to a specific location.
You can set this parameter to value returned from the
bookmark property, or to one of the following constant
bookmark values:
| |
offset:int (default = 0)beforeFirst or afterLast location.
| |
prefetch:int (default = 0) |
