Here's my class (original using Flex - ArrayCollection and now Royale -
ArrayList + ArrayListView):
package pt.solidsoft.framework.datamanager.model
{
import org.apache.royale.collections.ArrayListView;
import org.apache.royale.collections.ArrayList;
public class EntityList extends ArrayListView
{
public function EntityList(source:ArrayList = null)
{
super(source);
this.filterFunction = hideDeletedEntities;
}
private function hideDeletedEntities(item:Object):Boolean
{
if (item is Entity)
return item.EntityState != Entity.DELETED;
return true;
}
public function addEntity(item:IEntity):void
{
item.markAsAdded();
this.addItem(item);
}
public function addEntityAt(item:Entity, index:int):void
{
item.markAsAdded();
this.addItemAt(item, index);
}
public function addEntities(items:EntityList):void
{
for each (var item:Entity in items)
addEntity(item);
}
public function merge(items:EntityList):void
{
for each (var item:Entity in items.source)
{
addItem(item);
}
}
public function createEntity(item:Class):void
{
addEntity(new item as Entity);
}
public function deleteEntity(item:Entity):void
{
for (var i:int = this.length - 1; i >= 0; i--)
{
if (this[i] == item)
{
deleteEntityAt(i);
break;
}
}
}
public function deleteEntityAt(index:int):Object
{
//check if the index is valid
if (index < 0 || index > this.length)
return null;
//get the entity item
var item:Entity = this[index] as Entity;
//if the entity can me marked as deleted, then refresh the list
if (item.markAsDeleted())
{
this.refresh();
return item;
}
//real remove the item
return this.removeItemAt(index);
}
//remove of entities marked as deleted
public function compact():void
{
this.filterFunction = null;
for (var i:int = this.length - 1; i >= 0; i--)
{
if ((this.getItemAt(i) as Entity).isDeleted())
this.removeItemAt(i);
}
this.filterFunction = hideDeletedEntities;
this.refresh();
}
[Bindable("collectionChange")]
public function getFirstEntity():Object
{
if (this.length == 0)
return null;
return this[0] as Entity;
}
[Bindable("collectionChange")]
public function getLastEntity():Object
{
if (this.length == 0)
return null;
return this[this.length - 1] as Entity;
}
public function anyPending():Boolean
{
for each (var entity:Entity in this)
{
if (entity.EntityState != Entity.UNCHANGED)
return true;
}
return false;
}
public function haveEntities():Boolean
{
return this.length > 0;
}
}
}
