Reifies a method into a request. Subclasses must provide the necessary state and behavior.
An ACE_Method_Request is inserted in an ACE_Activation_Queue, where it is subsequently removed by a scheduler object (often derived from ACE_Task), which invokes the call() method.
This class is discussed in depth in the Active Object chapter of POSA2.

| ACE_Method_Request::~ACE_Method_Request | ( | void | ) | [virtual] |
Destructor.
| ACE_Method_Request::ACE_Method_Request | ( | const ACE_Method_Request & | ) | [private] |
Disallow copying and assignment.
| virtual int ACE_Method_Request::call | ( | void | ) | [pure virtual] |
Invoked by the scheduler to execute the request.
This method must be implemented by the subclass to perform the desired actions.
| void ACE_Method_Request::operator= | ( | const ACE_Method_Request & | ) | [private] |
| unsigned long ACE_Method_Request::priority | ( | void | ) | const |
Get priority.
| void ACE_Method_Request::priority | ( | unsigned long | prio | ) |
Set priority.
Priority values are user-defined. The default (set in the constructor) is 0. The priority value is used in the ACE_Activation_Queue::enqueue() method to order the method requests in the queue by priority. 0 is the lowest priority.
| prio | unsigned long, the new priority value for this object. |
unsigned long ACE_Method_Request::priority_ [protected] |
The priority of the request.
