FilteringCollection is an extension of Collection which provides possibilities to
Usage - In the current version each FilteringCollection provides a set of predefined qualifier constants which can be passed into the select(Object) method used to filter the elements. Generally qualifiers have the prefix QUALIFIER_. A second method sort(Object) is used to create a new instance with a different element ordering, which takes an orderB< constant. Generally orderBys have the prefix ORDERBY_: examples are ShippingOrder.ORDERBY_ITEMID, ShippingOrder.ORDERBY_ITEMPOSITION, and ORDERBY_REVERSE can be used to provide a FilteringCollection with the reverse ordering. An example with method ShippingOrder.getItems():
`
var allItems : FilteringCollection = shippingOrder.items;
var productItems : FilteringCollection = allItems.select(ShippingOrder.QUALIFIER_PRODUCTITEMS);
var serviceItems : FilteringCollection = allItems.select(ShippingOrder.QUALIFIER_SERVICEITEMS);
var byPosition : FilteringCollection = productItems.sort(ShippingOrder.ORDERBY_ITEMPOSITION);
var revByPosition: FilteringCollection = byPosition.sort(FilteringCollection.ORDERBY_REVERSE);
var mapByItemID : Map = allItems.asMap(); `
| Constant | Description |
|---|---|
| ORDERBY_REVERSE: Object | Pass this orderBy with the sort(Object) method to obtain a new FilteringCollection with the reversed sort order. |
This class does not have a constructor, so you cannot create it directly.
| Method | Description |
|---|---|
| asMap() | Returns a Map containing the elements of this FilteringCollection against a predefined key. |
| select(Object) | Select a new FilteringCollection instance by passing a predefined qualifier as an argument to this method. |
| sort(Object) | Select a new FilteringCollection instance by passing a predefined orderBy as an argument to this method. |

Pass this orderBy with the sort(Object) method to obtain a new FilteringCollection with the reversed sort order. Only use on a FilteringCollection which has been previously sorted.
Returns a Map containing the elements of this FilteringCollection against a predefined key. The key used is documented in the method returning the FilteringCollection and is typically the ItemID assigned to an element in the collection.
