#include <Method_Request.h>
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.

Invoked by the scheduler to execute the request.
This method must be implemented by the subclass to perform the desired actions.
- Returns
- int; not interpreted by ACE. The scheduler class must decide the meaning of this return value and act on it if needed.

|
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.
- Parameters
-
| prio | unsigned long, the new priority value for this object. |

| unsigned long ACE_Method_Request::priority_ |

The priority of the request.
