Chains_R
Return information about a Chain.
Syntax
Chains_R <ObjectPath> {ChainsOption}
Description
| {ChainsOption} | Description |
|---|---|
| EndObjectStrands <EndObjectPath> | Returns access data for all extended chain strands. Extended strands are the normal chain strands which have been lengthened to include the additional STK object specified as a parameter to this option.
This option is valid for Chains only. |
| Intervals | Returns a summary of the complete chain access intervals within the specified chain.
This command returns the equivalent of the "Complete Chain Access" report. This option is valid for Chains only. |
| Strands | The Chains_R Strands command allows you to identify possible access pathways through the specified chain. For a chain defined by a series of individual objects, only a single strand is possible. In the case where one or more objects in the chain are constellations, multiple strands are possible. Further, any constellation constraints (i.e., ANY OF, ALL OF, AT LEAST N, EXACTLY N) determine the number of possible strands for a chain that includes constellation objects.
This option is valid for Chains only |
| FromOperator | Identify the Operator constraints placed upon a constellation. It returns a list that includes the type of constraint applied to the specified constellation.
This option is valid for Constellations only The Operator {ChainsOption} is deprecated in STK 11.4. It will return the value of the FromOperator. |
| ToOperator | |
| Operator | |
| SubObjects | Identify all of the subobjects included in a chain or constellation. It returns a list that includes the type and name of each object. |
