Class Name: In Out
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>
is an input to the <Process> or
an output generated by the <Process>.
Primary Page in DRM Diagram:
Secondary Pages in DRM Diagram:
This class appears on only one page of the DRM class diagram.
Example
- Indicates that a particular DTED cell (<Source>
is an input to a terrain surface generation process
(<Process>).
- Indicates that an <Environment Root>
instance (<Source>) is the output of a high-level
environmental database generation process (<Process>).
FAQs
- What is the purpose of this class?
- This class provides a mechanism by which <Sources>
can be associated with <Processes> to describe the
overall creation of a transmittal.
A logical network of <Processes>
can be defined by linking the <Process> that generates
a particular <Source> to all of the
<Processes> that consume that
<Source>. For each associated
<Source>, <Process>
pair, the <In Out> instance identifies whether the
<Source> is an input or an output
of the <Process>.
Constraints
None.
Inherited Field Elements
This class has no inherited field elements.
Notes
Fields Notes
If SE_TRUE, the <Source> is an input to the <Process>.
If SE_FALSE, the <Source> is an output from the <Process>.
