This section specifies the template representing_activity_method_realization.

NOTE The template has been defined in the context of the capability representing_activity which provides an overall description of the relevant parts of the ISO 10303-239 information model and a description of related templates.

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 a relationship between an activty method and a detailed description of its realization.

Model diagrams

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

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:

act_method (Type= 'ENTITY (Activity_method)' )

The Activity_method for which further specification is being provided.

realized_by (Type= 'SELECT (activity_realization_select)' )

The item that realizes the Activity_method .

class_name (Type='CLASS')

"Activity method realization" (urn:plcs:rdl:std:Activity method realization), or subclass thereof, used to determine the role of the realization relationship.

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

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

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

The identifier of the External_class_library storing the definition of the class referenced by the parameter @class_name.

Reference parameters

The following reference parameters are defined for this template:

act_mthd_real(Type='ENTITY (Activity_method_realization)')

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

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

%^target = $representing_activity_method_realization.act_mthd_real%

where target is the parameter to which the Activity_method_realization 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.

Activity_method_realization

-- Mark the Activity_method_realization entity as
-- referable when this template is used by binding it to the reference
-- parameter act_mthd_real
%^act_mthd_real = Activity_method_realization%
Activity_method_realization.id = '/IGNORE'
Activity_method_realization.name = '/IGNORE'
Activity_method_realization.description = /IGNORE'
Activity_method_realization.activity_method -> @act_method
Activity_method_realization.realized_by -> @realized_by

-- provide the role of the realization by classifying the Activity_method_realization
/assigning_reference_data(
    items=^act_mthd_real,
    class_name=@class_name,
    ecl_id=@ecl_id)/

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Activity_method_realization.id	'/IGNORE'	—
Activity_method_realization.name	'/IGNORE'	—
Activity_method_realization.description	/IGNORE'	—

Instance diagrams

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

/representing_activity_method_realization(act_method='#1', realized_by='#2', class_name='Task_step_realization', ecl_id='urn:plcs:rdl:sample')/

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

Figure 3 — Entities instantiated by representing_activity_method_realization 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:

/representing_activity_method_realization(act_method='#1', realized_by='#2', class_name='Task_step_realization', ecl_id='urn:plcs:rdl:sample')/

Characterizations

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