The SEDRIS Data Representation Model
APPENDIX A - Classes In Out |
|---|
An instance of this DRM class specifies whether a <Source> instance that is associated with a <Process Step> instance is an input to the <Process Step> instance or an output generated by the <Process Step> instance.
An <In Out> instance with input = SE_TRUE is provided to indicate 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).
An <In Out> instance with input = SE_FALSE is provided to indicate 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).
This class provides a mechanism by which <Source> instances can be associated with <Process Step> instances to describe the overall creation of a transmittal. A logical network of <Process Step> instances can be specified by linking the <Process Step> instance that generates a particular <Source> instance to all of the <Process Step> instances that consume that <Source> instance. For each associated <Source> instance / <Process Step> instance pair, the <In Out> instance identifies whether the <Source> instance is an input or an output of the <Process Step> instance.
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.
