getProperty
Description
[
obtains the value and units of the property specified in the
propertyValue
,propertyUnits
] = getProperty(element
,propertyName
)propertyName
argument. Get the property corresponding to an applied
stereotype by qualified name
"<profile>.<stereotype>.<property>"
.
Examples
Get Property from Component
Get the weight
property from a component with
sysComponent
stereotype applied.
Create a model with a component called Component
.
model = systemcomposer.createModel("archModel",true); arch = get(model,"Architecture"); comp = addComponent(arch,"Component");
Create a profile with a stereotype with a property, then apply the profile to the model.
profile = systemcomposer.profile.Profile.createProfile("sysProfile"); base = profile.addStereotype("sysComponent"); base.addProperty("weight",Type="double",DefaultValue="10",Units="g"); model.applyProfile("sysProfile");
Apply the stereotype to the component, and set a new weight property.
applyStereotype(comp,"sysProfile.sysComponent") setProperty(comp,"sysProfile.sysComponent.weight","5","g")
Get the weight property with units.
[val,units] = getProperty(comp,"sysProfile.sysComponent.weight")
val = '5' units = 'g'

architecture | A System Composer™ architecture represents a system of components and how they interface with each other structurally and behaviorally. |
Different types of architectures describe different aspects of systems. You can use views to visualize a subset of components in an architecture. You can define parameters on the architecture level using the Parameter Editor. | |
model | A System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors. |
Perform operations on a model:
A System Composer model is stored as an SLX file. | Create Architecture Model with Interfaces and Requirement Links |
component | A component is a nontrivial, nearly independent, and replaceable part of a system that fulfills a clear function in the context of an architecture. A component defines an architectural element, such as a function, a system, hardware, software, or other conceptual entity. A component can also be a subsystem or subfunction. | Represented as a block, a component is a part of an architecture model that can be separated into reusable artifacts. Transfer information between components with:
| Components |
port | A port is a node on a component or architecture that represents a point of interaction with its environment. A port permits the flow of information to and from other components or systems. |
There are different types of ports:
| Ports |
connector | Connectors are lines that provide connections between ports. Connectors describe how information flows between components or architectures. | A connector allows two components to interact without defining the nature of the interaction. Set an interface on a port to define how the components interact. | Connections |

stereotype | A stereotype is a custom extension of the modeling language. Stereotypes provide a mechanism to extend the architecture language elements by adding domain-specific metadata. | Apply stereotypes to model elements such as root-level architecture, component architecture, connectors, ports, data interfaces, value types, functions, requirements, and links. Functions only apply to software architectures. You must have a Requirements Toolbox™ license to apply stereotypes to requirements and links. A model element can have multiple stereotypes. Stereotypes provide model elements with a common set of property fields, such as mass, cost, and power. | Extend Architectural Design Using Stereotypes |
property | A property is a field in a stereotype. You can specify property values for each element to which the stereotype is applied. | Use properties to store quantitative characteristics, such as weight or speed, that are associated with a model element. Properties can also be descriptive or represent a status. You can view and edit the properties of each element in the architecture model using the Property Inspector. | |
profile | A profile is a package of stereotypes that you can use to create a self-consistent domain of element types. | Author profiles and apply profiles to a model using the Profile Editor. You can store stereotypes for a project in one or several profiles. When you save profiles, they are stored in XML files. |

physical subsystem | A physical subsystem is a Simulink® subsystem with Simscape™ connections. | A physical subsystem with Simscape connections uses a physical network approach suited for simulating systems with real physical components and represents a mathematical model. | Implement Component Behavior Using Simscape |
physical port | A physical port represents a Simscape physical modeling connector port called a Connection Port (Simscape). | Use physical ports to connect components in an architecture model or to enable physical systems in a Simulink subsystem. | Define Physical Ports on Component |
physical connector | A physical connector can represent a nondirectional conserving connection of a specific physical domain. Connectors can also represent physical signals. | Use physical connectors to connect physical components that represent features of a system to simulate mathematically. | Architecture Model with Simscape Behavior for a DC Motor |
physical interface | A physical interface defines the kind of
information that flows through a physical port. The same interface can be assigned to multiple
ports. A physical interface is a composite interface equivalent to a | Use a physical interface to bundle physical elements to describe a physical model using at least one physical domain. | Specify Physical Interfaces on Ports |
