6.6.4 JobRequestor Interface

Module: AbstractIF

Interface: JobRequestor

Inherited Interface: Implementation Dependent

Description: In order to request work of a JobSupervisor using the requestJob operation, a component

must implement the JobRequestor interface. This is a companion interface to

JobSupervisor. The JobRequestor may also subscribe to the state change events of the

Job, if more detail is required.

interface JobRequestor {

Exceptions: None.

Published Events: None.

Provided Services:

/* The Job has transitioned to a new state. Required for transition to Executing from Queued and for any transition

to a Finished sub-state. This operation is in addition to the required JobStateChangedEvent notifications. */

void informJobStateChange (

in Job aJob,

in Job::JobState previousState,

in Job::JobState newState)

raises (Global::FrameworkErrorSignal);

}; // JobRequestor

Contracted Services: None.

Dynamic Model: None.

Scenario:

aJobRequestor:

JobRequestor

aJobSupervisor:

JobSupervisor

aJob :Job

1: requestJob (Properties, JobRequestor)

2: Return Job

3: informJobStateChange (Job, Queued, Executing)

4: informJobStateChange (Job, Active, Finished)

Figure 6

Job Supervision Scenario

6.6.4.1 Figure 6 shows the most basic of scenarios for Job Supervision interactions. It proceeds in this fashion:

6.6.4.1.1 The JobRequestor populates a JobSpecification then requests a Job according to that specification.

6.6.4.1.2 In response to the Job request, the JobSupervisor facilitates the creation of a Job to represent the task. A

handle to the Job is returned to the JobRequestor (assuming the Job request is accepted).

6.6.4.1.3 The Job Supervision component (e.g. in the form of the Job) informs the JobRequestor when the Job

begins.

6.6.4.1.4 The Job Supervision component (e.g. in the form of the Job) informs the JobRequestor when the Job has

completed (assuming successful completion). It also issues events for each state change (not shown in the scenario

diagram).

6.7 Factory Component

6.7.1 The Factory interfaces provide configuration services to specify the existence and connectivity of factory

resources that constitute a factory. This includes area configuration and the registration of CIM system components,

and the ability to dynamically configure a factory to enforce business policy.

6.7.1.1 These interfaces are included here to satisfy dependencies and meet needs of other CIM Framework

Components. These interfaces will be moved to the Factory Operations Component in a subsequent revision ballot.
