Property

Create query to select non-evaluated values for object properties or stereotype properties for elements

Syntax

query = Property(name)

Description

query = Property(name) creates a query object that the find method and the createView method use to select non-evaluated values for object properties or stereotype properties for elements based on a specified property 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.

scKeylessEntrySystem

Open the model.

m = systemcomposer.openModel('KeylessEntryArchitecture');

Create a query to find components that contain the character vector 'Sensor' in their 'Name' property and run the query, displaying the first.

constraint = contains(Property('Name'),'Sensor');
sensors = find(m,constraint,'Recurse',true,'IncludeReferenceModels',true);
sensors(1)

ans = 

1×1 cell array

    {'KeylessEntryArchitecture/Door Lock//Unlock System/Front Driver Door Lock Sensor'}

Input Arguments

name — Property name

character vector

Property name for model element, specified as a character vector 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.

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. Construct views by pulling in elements manually. Views create a simplified way to work with complex architectures by focusing on certain parts of the architecture design.	You can use different types of views to represent the system: Operational views demonstrate how a system will be used and should be well integrated with requirements analysis. Functional views focus on what the system must do to operate. Physical views show how the system is constructed and configured. A viewpoint represents a stakeholder perspective that specifies the contents of the view.	Create Architecture Views Interactively 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 Architectural 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 a Model Using Queries
