The AbstractOperation class represents an individual method on a
service. An Operation can be called either by invoking the function of the
same name on the service or by accessing the Operation as a property on the
service and calling the send() method.
This property is set usually by framework code which wants to modify the
behavior of a service invocation without modifying the way in which the
service is called externally.
Like resultType, used to define the ActionScript class used by a given operation though
this property only applies to operations which return a multi-valued result (e.g.
Dispatched when an Operation invocation successfully returns.

The arguments to pass to the Operation when it is invoked. If you call
the send() method with no parameters, an array based on
this object is sent. If you call the send() method with
parameters (or call the function directly on the service) those
parameters are used instead of whatever is stored in this property.
For RemoteObject Operations the associated argumentNames array determines
the order of the arguments passed.

The name of this Operation. This is how the Operation is accessed off the
service. It can only be set once.

This is a hook primarily for framework developers to register additional user
specified properties for your operation.
Provides convenient access to the service on which the Operation
is being invoked. Note that the service cannot be changed after
the Operation is constructed.

Constructor
public function AbstractOperation(service:AbstractService = null, name:String = null)
Language Version :
ActionScript 3.0
Product Version :

Runtime Versions :
Flash Player 9, AIR 1.1
Creates a new Operation. This is usually done directly by the MXML
compiler or automatically by the service when an unknown Operation has
been accessed. It is not recommended that a developer use this
constructor directly.
Parameters
service:AbstractService (default = null) — The service on which the Operation is being invoked.
name:String (default = null) — The name of the new Operation.
Executes the method. Any arguments passed in are passed along as part of
the method call. If there are no arguments passed, the arguments object
is used as the source of parameters.
Parameters
... args — Optional arguments passed in as part of the method call. If there
are no arguments passed, the arguments object is used as the source of
parameters.
Returns
AsyncToken — AsyncToken object.
The same object is available in the result and
fault events from the token property.
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 contains the
details of what caused this event.
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.
token
The token that represents the call
to the method. Used in the asynchronous completion token pattern.
Dispatched when an Operation invocation successfully returns.
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.
