This section specifies the template assigning_task_method_version.

NOTE An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes how to represent an assignment relationship between a Task_method_version and the assignment target.

Model diagrams

The EXPRESS-G diagram in Figure 1 shows the templates and EXPRESS entities that are required to represent the template "assigning_task_method_version". The text highlighted in blue shows the template parameters.

The diagram shows the use of a Task_method_version_assignment to link a Task_method_version to the target in the role given by the reference data.

The graphic for the template to be used in other EXPRESS-G diagrams is shown in Figure 2 below.

Input parameters

The following input parameters are defined for this template:

assignment_role (Type='CLASS')

The role of the assignment.

The following classes and their sub-classes can be used:

classifications: "Task_method_version_assignment" (urn:plcs:rdl:std:Task_method_version_assignment)

role_ecl_id (Default=urn:plcs:rdl:std,Type='URN')

The External_class_library storing the definition of the class referenced by the parameter @assignment_role

item (Type= 'SELECT (task_item)' )

The target element of the assignment.

task_method_version (Type= 'ENTITY (Task_method_version)' )

The Task_method_version that is assigned.

Reference parameters

The following reference parameters are defined for this template:

task_mv_asg(Type='ENTITY (Task_method_version_assignment)')

Allow the Task_method_version_assignment entity instantiated in this path to be referenced when this template is used.

Note: The Task_method_version_assignment entity can be referenced in a template path by:

%^target = $assigning_task_method_version.task_mv_asg%

where target is the parameter to which the Task_method_version_assignment is bound.

Instantiation path

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

Task_method_version_assignment
%^task_mv_asg = Task_method_version_assignment%
Task_method_version_assignment.role = '/IGNORE'
Task_method_version_assignment.items -> @item
Task_method_version_assignment.assigned_activity_method -> @task_method_version

-- Assign the role of the assignment
/assigning_reference_data(
    items=^task_mv_asg,
    class_name=@assignment_role,
    ecl_id=@role_ecl_id)/

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Task_method_version_assignment.role	'/IGNORE'	Applied_activity_method_assignment.role

Instance diagrams

The instance diagram in Figure 3 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/assigning_task_method_version(assignment_role='Task_affected_item', role_ecl_id='urn:plcs:rdl:sample', item='#1', task_method_version='#2')/

(an illustration of the consolidated assigning_task_method_version template is shown in Figure 4 below.)

Figure 3 — Entities instantiated by assigning_task_method_version template

The instance diagram in Figure 4 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:

/assigning_task_method_version(assignment_role='Task_affected_item', role_ecl_id='urn:plcs:rdl:sample', item='#1', task_method_version='#2')/

Characterizations

No common characterizations of the template assigning_task_method_version have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
