Property Detail

concurrency

property

concurrency:String

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Value that indicates how to handle multiple calls to the same service. The default value is multiple. The following values are permitted:

multiple - Existing requests are not cancelled, and the developer is responsible for ensuring the consistency of returned data by carefully managing the event stream. This is the default.
single - Making only one request at a time is allowed on the method; additional requests made while a request is outstanding are immediately faulted on the client and are not sent to the server.
last - Making a request causes the client to ignore a result or fault for any current outstanding request. Only the result or fault for the most recent request will be dispatched on the client. This may simplify event handling in the client application, but care should be taken to only use this mode when results or faults for requests may be safely ignored.

Implementation
public function get concurrency():String
public function set concurrency(value:String):void

convertParametersHandler

property

public var convertParametersHandler:Function

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

An optional function, primarily intended for framework developers who need to install a function to get called with the parameters passed to each remote object invocation. The function takes an array of parameters and returns the potentially altered array. The function definition should look like: function myParametersFunction(parameters:Array):Array

convertResultHandler

property

public var convertResultHandler:Function

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

An optional function, primarily intended for framework developers who need to install a hook to process the results of an operation before notifying the result handlers. The function definition should look like: function myConvertResultsFunction(result: operation:AbstractOperation): It is passed the result just after the makeObjectsBindable conversion has been done but before the result event is created.

destination

property

destination:String[override]

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

throwItemPendingErrors

property

throwItemPendingErrors:Boolean

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Set this property to false if you want to suppress item pending errors when lazily fetched or unpaged data is accessed. Instead of throwing the error, null is returned for a property value or a getItemAt() call in an ArrayCollection.

The size() method returns 0 elements for a list for which the size has not yet been fetched from the server. When the element is returned from the server, the appropriate PropertyChangeEvent and CollectionEvent events are dispatched.

Implementation
public function get throwItemPendingErrors():Boolean
public function set throwItemPendingErrors(value:Boolean):void

verifyEntityClasses

property

verifyEntityClasses:Boolean

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Flash Player 10.2, AIR 2.6

If true, verify that all managed entities are present. When the service is initialized each of the managed entities specified by the service are validated to ensure a class with the appropriate alias exists in the client. You may set this to false if your client does not use all of the managed entities of a service and you do not want to link classes you are not using in to your code. The default is true.

Implementation
public function get verifyEntityClasses():Boolean
public function set verifyEntityClasses(value:Boolean):void

Constructor Detail

ManagedRemoteService

()

Constructor

public function ManagedRemoteService(destinationId:String = null)

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Creates a new ManagedRemoteService.

Parameters

destinationId:String (default = null) — [optional] Destination of the ManagedRemoteService

Method Detail

addEventListener

()

method

override public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Add an event listener to the service.

Parameters

	`type:String` — The type of event.

	`listener:Function` — The listener function that processes the event. This function must accept an Event object as its only parameter and must return nothing.

	`useCapture:Boolean` (default = `false`) — Determines whether the listener works in the capture phase or the target and bubbling phases. If useCapture is set to true, the listener processes the event only during the capture phase and not in the target or bubbling phase. If useCapture is false, the listener processes the event only during the target or bubbling phase. To listen for the event in all three phases, call addEventListener twice, once with useCapture set to true, then again with useCapture set to false.

	`priority:int` (default = `0`) — The priority level of the event listener. The priority is designated by a signed 32-bit integer. The higher the number, the higher the priority. All listeners with priority n are processed before listeners of priority n-1. If two or more listeners share the same priority, they are processed in the order in which they were added. The default priority is 0.

	`useWeakReference:Boolean` (default = `false`) — Determines whether the reference to the listener is strong or weak. A strong reference (the default) prevents your listener from being garbage-collected. A weak reference does not.

commitRequiredOn

()

method

public function commitRequiredOn(item:Object):Boolean

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Indicates if there are pending changes for this particular object. If the ManagedRemoteService has not been initialized, either by invoking an operation or explicitly calling initialize(), this method will always return false.

Parameters

item:Object — The object that might have changes.

Returns

Boolean — true if the object has pending changes.

getOperation

()

method

override public function getOperation(name:String):AbstractOperation

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Returns an Operation of the given name. If the Operation wasn't created beforehand, a new mx.rpc.remoting.Operation is created during this call. Operations are usually accessible by simply naming them after the service variable (myService.someOperation), but if your Operation name happens to match a defined method on the service (like setCredentials), you can use this method to get the Operation instead.

Parameters

name:String — Name of the Operation.

Returns

AbstractOperation — Operation that executes for this name.

initializeService

()

method

public function initializeService():mx.rpc:AsyncToken

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Force initialization of the Managed Remote Service. Generates a ResultEvent on success and a DataServiceFaultEvent on failure. Note: do not use the initialize() function as it does not set up the ManagedRemoteService.

Returns

mx.rpc:AsyncToken

logout

()

method

override public function logout():void

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Log the user out of the destination for the service and releases all managed collections and items. Any Data Services associated with the Managed Remote service also have logout() called.

releaseCollection

()

method

 public function releaseCollection(view:ListCollectionView, clear:Boolean = false, copyStillManagedItems:Boolean = true):void

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Releases the specified collection from management by the underlying DataService. (see DataService.releaseCollection() for further notes)

Parameters

	`view:ListCollectionView` — ListCollectionView reference that should no longer receive remote updates.

	`clear:Boolean` (default = `false`) — Boolean indicating if the all items should be removed from the list. In addition no copies will be made of any item.

	`copyStillManagedItems:Boolean` (default = `true`) — Boolean if there are other managed references to items in this collection, this parameter controls whether copies of those items are made so that after this call you are guaranteed that there are no longer any managed items in the collection. Specifying both clear and this option as false will result in the fastest way to release managed references.

releaseItem

()

method

 public function releaseItem(item:IManaged, dontClearStillManagedItems:Boolean = true, copyStillManagedItems:Boolean = true):IManaged

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

Releases the specified item from management by the underlying DataService. (see DataService.releaseItem() for further notes)

Parameters

	`item:IManaged` — IManaged reference to the item to be released.

	`dontClearStillManagedItems:Boolean` (default = `true`) — Boolean indicating whether to copy (true) or clear (false) items should the item be still managed by another collection or reference after this release.

	`copyStillManagedItems:Boolean` (default = `true`) — Boolean indicating if we should make copies of the items which are still managed in the graph of objects. Passing a value of false will leave the object graph unchanged even if some objects in the graph are still managed through other references.

Returns

IManaged — Reference to the released item. This reference may be a copy of the item specified if copyStillManagedItems is true and dontClearStillManagedItems is true and the item is still being referenced. This can occur if more than one call to ManagedRemoteService.yourGetItemHere() for this same item is made, or if this item is referenced by a collection returned from a call to ManagedRemoteService.yourFillMethodHere().

removeEventListener

()

method

override public function removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void

Language Version:

ActionScript 3.0

Remove specified listener from the service.

Parameters

	`type:String` — The type of event.

	`listener:Function` — The listener object to remove.

	`useCapture:Boolean` (default = `false`) — Specifies whether the listener was registered for the capture phase or the target and bubbling phases. If the listener was registered for both the capture phase and the target and bubbling phases, two calls to removeEventListener() are required to remove both, one call with useCapture() set to true, and another call with useCapture() set to false.

revertChanges

()

method

public function revertChanges(item:IManaged = null):Boolean

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Event Object Type: mx.data.events.DataConflictEvent
property DataConflictEvent.type = mx.data.events.DataConflictEvent.CONFLICT

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

The DataConflictEvent.CONFLICT event is dispatched when a conflict is detected between pending local changes and changes submitted by another client, or when changes submitted by this client conflict with those in the remote destination. Each ManagedRemoteService instance sends conflict events only for items of this particular destination.

The CONFLICT constant defines the value of the type property of the event object for a conflict event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`conflict`	The Conflict object that holds the conflict that occurred.
`message`	The Message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

fault

Event Object Type: mx.data.events.DataServiceFaultEvent
property DataServiceFaultEvent.type = mx.data.events.DataServiceFaultEvent.FAULT

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

The DataServiceFaultEvent.FAULT event is dispatched when a service call fails due to an error.

The FAULT constant defines the value of the type property of the event object for a fault event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	true, calling preventDefault() from the associated token's responder.fault method will prevent the service or operation from dispatching this event
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`fault`	The Fault object that holds the conflict that occurred.
`item`	The item that generated the fault.
`identity`	The identity of of the item that generated the fault.
`message`	The Message associated with this event.
`token`	The token that represents the call to the method. Used in the asynchronous completion token pattern.

Event Object Type: mx.messaging.events.MessageEvent
property MessageEvent.type = mx.messaging.events.MessageEvent.MESSAGE

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

The MessageEvent.MESSAGE event is dispatched when the remote destination pushes a notification of a data operation. For example, when data is updated in the remote destination an update operation is sent to all clients listening, this operation is converted to a message event on this DataService instance.

The MESSAGE event type; dispatched upon receipt of a message.

The value of this constant is "message".

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`message`	The message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

Language Version:

ActionScript 3.0

Product Version:

Adobe Digital Enterprise Platform Data Services for Java EE 4.6

Runtime Versions:

Flash Player 10.2, AIR 2.6

The ResultEvent.RESULT event is dispatched when a service call successfully returns. For example a call to the fill() method dispatches this event if the call is successful.

The RESULT event type.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	true, preventDefault() from the associated token's responder.result method will prevent the service or operation from dispatching this event
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`message`	The Message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
`result`	Result that the RPC call returns.
`token`	The token that represents the indiviudal call to the method. Used in the asynchronous completion token pattern.
