HasInterface

Create query to select architectural elements with interface on port based on specified subconstraint

Syntax

query = HasInterface(subconstraint)

Description

query = HasInterface(subconstraint) creates a query 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.

openProject("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 = 10x1 cell
    {'KeylessEntryArchitecture/FOB Locater System/FOB Locater Module'         }
    {'KeylessEntryArchitecture/Engine Control System'                         }
    {'KeylessEntryArchitecture/Sound System'                                  }
    {'KeylessEntryArchitecture/Door Lock//Unlock System'                      }
    {'KeylessEntryArchitecture/Lighting System'                               }
    {'KeylessEntryArchitecture/Sound System/Sound Controller'                 }
    {'KeylessEntryArchitecture/Lighting System/Lighting Controller'           }
    {'KeylessEntryArchitecture/Door Lock//Unlock System/Door Lock Controller' }
    {'KeylessEntryArchitecture/FOB Locater System'                            }
    {'KeylessEntryArchitecture/Engine Control System/Keyless Start 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.	Create Custom Views Using Architecture Views Gallery 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.	Create Architecture Views Interactively Create Architecture Views Programmatically
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.	System Composer™ has two types of hierarchy diagrams: Component hierarchy diagrams display components in tree form with parents above children. In a component hierarchy view, each referenced model is represented as many times as it is used. Architecture hierarchy diagrams display unique component architecture types and their relationships using composition connections. In an architecture hierarchy view, each referenced model is represented only once.	Display Component Hierarchy and Architecture Hierarchy Using Views
