Syntax

Description

[query](#mw%5F5c482cb7-8134-40ca-89cf-9ce4c9b96a31%5Fsep%5Fmw%5F565a4cf6-f69a-4ec7-822c-cd8586062aff) = Property([name](#mw%5F5c482cb7-8134-40ca-89cf-9ce4c9b96a31%5Fsep%5Fmw%5Fdff9cb67-ef3f-4c9c-ab1b-ca65fd5eb581)) creates a query query that the find and createView functions use to select non-evaluated values for object properties or stereotype properties for elements based on a specified property namename.

Examples

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 to find components that contain Sensor in their Name property and run the query, displaying the first.

constraint = contains(Property("Name"),"Sensor"); sensors = find(model,constraint,Recurse=true,IncludeReferenceModels=true); query = sensors(1)

query = 1×1 cell array {'KeylessEntryArchitecture/Door Lock//Unlock System/Rear Pass Door Lock Sensor'}

Input Arguments

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 GalleryModeling 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 InteractivelyCreate 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. 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
