Property
Create query to select non-evaluated values for object properties or stereotype properties for elements
Since R2019b
Syntax
Description
creates a query query
= Property(name
)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 name
name
.
Examples
Find Model Elements that Satisfy Property
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 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 = 1x1 cell array
{'KeylessEntryArchitecture/Door Lock//Unlock System/Rear Pass Door Lock Sensor/Door Lock Sensor'}
Input Arguments
name
— Property name
character vector | string
Property name for model element, specified in the form "<profile>.<stereotype>.<property>"
or any property on the designated class.
Example: "Name"
Example: "AutoProfile.BaseComponent.Latency"
Data Types: char
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:
