Detailed Description

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.

Member Function Documentation

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.

int; not interpreted by ACE. The scheduler class must decide the meaning of this return value and act on it if needed.

void ACE_Method_Request::operator= ( const ACE_Method_Request  )  [private]

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.
