Abstract Class Name: Base State Data

Superclass - SEDRIS Abstract Base

Subclasses

• Feature State Data
• Geometry State Data

Definition

The value (or value range) of an active_state_value field being used to differentiate <State Related> components. The semantics of the Base State Data is obtained from the list of EDCS State Codes (ESCs).

Primary Page in DRM Diagram:

• 9

Example

1. Identifies one of alternative appearances, e.g.
   1. aircraft hatch open vs. hatch closed,
   2. which of 4 damage states,
   3. a comparable state for a forest would be healthy vs. burned.

Constraints

• Active State Value

Fields Notes

state_value_min

 the minimum (inclusive lower limit) of a <State Related>
 component branch selection criterion - expected to be either
 an SE_FLOAT32 (for continuous states) or an EDCS Attribute
 Code (EAC) enumerator (for EDCS State Codes defined as
 enumerations)

state_value_max

 the maximum (exclusive upper limit) of a <State Related>
 component branch selection criterion - expected to be either
 an SE_FLOAT32 (for continuous states) or an EDCS Attribute
 Code (EAC) enumerator (for EDCS State Codes defined as
 enumerations)
 If state_value_min == state_value_max, then a discrete single value
 is represented (just like a traditional page/switch value number).
 The ranges are meant to provide more granularity to the
 implementation of states, without requiring new enumerations.
 See examples in <State Related Geometry>.
