hasRoot | eigenschap |
hasRoot:Boolean [alleen-lezen] | Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
A flag that, if true, indicates that the current data provider has a root node;
for example, a single top-level node in a hierarchical structure.
XML and Object are examples of data types that have a root node,
while Lists and Arrays do not.

openNodes | eigenschap |
openNodes:Object| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
An Array of Objects containing the data provider element for all the open branch nodes of the data.
Implementatie

showRoot:Boolean| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
A Boolean flag that specifies whether to display the data provider's root node.
If the source data has a root node, and this property is set to
false, the collection will not include the root item.
Only the descendants of the root item will be included in the collection.
This property has no effect on a source with no root node, such as List and Array objects.
De standaardwaarde is true.
Deze eigenschap kan als de bron voor gegevensbinding worden gebruikt. Wanneer deze eigenschap wordt gewijzigd, wordt de gebeurtenis propertyChange verzonden.

public function addChild(parent:Object, newChild:Object):Boolean| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Adds a child node to a node of the data.
Parameters
parent:Object — The Object that defines the parent node.
| |
newChild:Object — The Object that defines the new node.
|
Boolean — true if the node is added successfully.
|
addChildAt | () | methode |
public function addChildAt(parent:Object, newChild:Object, index:int):Boolean| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Add a child node to a node at the specified index. This implementation does the following:
- If the
parentis null or undefined, inserts thechildat the specifiedindexin the collection specified bysource. - If the
parenthas achildrenfield or property, the method adds thechildto it at theindexlocation. In this case, thesourceis not required. - If the
parentdoes not have achildrenfield or property, the method adds thechildrento theparent. The method then adds thechildto the parent at theindexlocation. In this case, thesourceis not required. - If the
indexvalue is greater than the collection length or number of children in the parent, adds the object as the last child.
Parameters
parent:Object — The Object that defines the parent node.
| |
newChild:Object — The Object that defines the child node.
| |
index:int — The 0-based index of where to insert the child node.
|
Boolean — true if the child is added successfully.
|

contains | () | methode |
public function contains(item:Object):Boolean| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Checks the collection for the data item using standard equality test.
Parameters
item:Object — The Object that defines the node to look for.
|
Boolean — true if the data item is in the collection,
and false if not.
|
createCursor | () | methode |
public function createCursor():IViewCursor| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |

public function getChildren(node:Object):ICollectionView| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Returns a collection of children, if they exist.
Parameters
node:Object — The Object that defines the node.
If null, return a collection of top level nodes.
|
ICollectionView — ICollectionView instance containing the child nodes.
|
getNodeDepth | () | methode |
getParentItem | () | methode |
public function getParentItem(node:Object):*| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Returns the parent of a node.
The parent of a top-level node is null.
Parameters
node:Object — The Object that defines the node.
|
* — The parent node containing the node,
null for a top-level node,
and undefined if the parent cannot be determined.
|
openNode | () | methode |
refresh | () | methode |
public function refresh():Boolean| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Applies the sort and filter to the view.
The ICollectionView does not detect changes to a sort or
filter automatically, so you must call the refresh()
method to update the view after setting the sort
or filterFunction property.
If your ICollectionView implementation also implements
the IMXMLObject interface, you should to call the
refresh() method from your initialized()
method.
Returns true if the refresh was successful
and false if the sort is not yet complete
(e.g., items are still pending).
A client of the view should wait for a CollectionEvent event
with the CollectionEventKind.REFRESH kind
property to ensure that the refresh() operation is
complete.
Boolean — true if the refresh() was complete,
false if the refresh() is incomplete.

Removes the child node from the parent node.
Parameters
parent:Object — The Object that defines the parent node,
and null for top-level nodes.
| |
child:Object — The Object that defines the child node to be removed.
|
Boolean — true if the node is removed successfully.
|
removeChildAt | () | methode |
public function removeChildAt(parent:Object, index:int):Boolean| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
Removes the child node from a node at the specified index.
