HasInterface
Create query to select architectural elements with interface on port based on specified subconstraint
Since R2019b
Description
creates a query query
= HasInterface(subconstraint
)query
that the find
and createView
functions use to select architectural elements with an interface
that satisfies the given subconstraint subconstraint
.
Examples
Construct Query to Select All Port Interfaces
Import the package that contains all of the System Composer™ queries.
import systemcomposer.query.*
Open the Simulink® project file for the keyless entry system.
scKeylessEntrySystem
Load the architecture model.
model = systemcomposer.loadModel("KeylessEntryArchitecture");
Create a query for all the interfaces in a port with KeyFOBPosition
in the Name
and run the query.
constraint = HasPort(HasInterface(contains(Property("Name"),"KeyFOBPosition"))); portInterfaces = find(model,constraint,Recurse=true,IncludeReferenceModels=true)
portInterfaces = 10×1 cell
{'KeylessEntryArchitecture/Door Lock//Unlock System' }
{'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller' }
{'KeylessEntryArchitecture/Engine Control System' }
{'KeylessEntryArchitecture/Engine Control System/Keyless Start Controller'}
{'KeylessEntryArchitecture/FOB Locator System' }
{'KeylessEntryArchitecture/FOB Locator System/FOB Locator Module' }
{'KeylessEntryArchitecture/Lighting System' }
{'KeylessEntryArchitecture/Lighting System/Lighting Controller' }
{'KeylessEntryArchitecture/Sound System' }
{'KeylessEntryArchitecture/Sound System/Sound Controller' }
Input Arguments
subconstraint
— Condition restricting the query
query constraint object
Condition restricting the query, specified as a systemcomposer.query.Constraint
object.
Output Arguments
query
— Query
query constraint object
Query, returned as a systemcomposer.query.Constraint
object.

Definitions
Term | Definition | Application | More Information |
---|---|---|---|
view | A view shows a customizable subset of elements in a model. Views can be filtered based on stereotypes or names of components, ports, and interfaces, along with the name, type, or units of an interface element. Create views by adding elements manually. Views create a simplified way to work with complex architectures by focusing on certain parts of the architectural design. |
You can use different types of views to represent the system. Switch between a component diagram, component hierarchy, or architecture hierarchy. For software architectures, you can switch to a class diagram view. A viewpoint represents a stakeholder perspective that specifies the contents of the view. | Modeling System Architecture of Keyless Entry System |
element group | An element group is a grouping of components in a view. | Use element groups to programmatically populate a view. | |
query | A query is a specification that describes certain constraints or criteria to be satisfied by model elements. | Use queries to search elements with constraint criteria and to filter views. | Find Elements in Model Using Queries |
component diagram | A component diagram represents a view with components, ports, and connectors based on how the model is structured. | Component diagrams allow you to programmatically or manually add and remove components from the view. | Inspect Components in Custom Architecture Views |
hierarchy diagram | You can visualize a hierarchy diagram as a view with components, ports, reference types, component stereotypes, and stereotype properties. |
There are two types of hierarchy diagrams:
