Class Name: In Out

Superclass - <SEDRIS Abstract Base>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies whether a <Source> instance that is associated with a <Process Step> is an input to the <Process Step> or an output generated by the <Process Step>.

Primary Page in DRM Diagram:

Secondary Pages in DRM Diagram:

This class appears on only one page of the DRM class diagram.

Example

  1. Indicates that a particular DTED cell (represented by a <Source> instance) is an input to a terrain surface generation process (represented by a <Process Step> instance).

  2. Indicates that an <Environment Root> instance (represented by a <Source> instance) is the output of a high-level environmental database generation process (represented by a <Process Step> instance).

FAQs

What is the purpose of this class?

This class provides a mechanism by which <Sources> can be associated with <Process Step>s to describe the overall creation of a transmittal. A logical network of <Process Step>s can be defined by linking the <Process Step> that generates a particular <Source> to all of the <Process Step>s that consume that <Source>. For each associated <Source>, <Process Step> pair, the <In Out> instance identifies whether the <Source> is an input or an output of the <Process Step>.

Constraints

Inherited Field Elements

This class has no inherited field elements.

Field Elements

SE_Boolean input; (notes)

Notes

Fields Notes


input

 If the value of the input field is SE_TRUE, the given <Source>
 instance is an input to the <Process Step> instance; otherwise,
 the <Source> instance is an output from the <Process Step> instance.
