createOwnedType

Create owned value type on data element or function argument

Since R2021b

Syntax

ownedType = createOwnedType(dataElement)

ownedType = createOwnedType(dataElement,Name=Value)

Description

ownedType = createOwnedType(dataElement) creates an owned value type on a data element or function argument. An owned interface is an interface that is local to a specific port and not shared in a data dictionary or the model dictionary.

ownedType = createOwnedType(dataElement,Name=Value) creates an owned value type on a data element or function argument with additional options.

Examples

Create Owned Value Type on Data Element on Architecture Port

model = systemcomposer.createModel("archModel");
 
port = model.Architecture.addPort("inPort","in");
interface = port.createInterface("DataInterface");
element = interface.addElement("newElement");
subInterface = element.createOwnedType

subInterface = 

  ValueType with properties:

           Name: ''
       DataType: 'double'
     Dimensions: '1'
          Units: ''
     Complexity: 'real'
        Minimum: '[]'
        Maximum: '[]'
    Description: ''
          Owner: [1×1 systemcomposer.interface.DataElement]
          Model: [1×1 systemcomposer.arch.Model]
           UUID: 'd184ab90-2be9-4acc-9d94-ed62d0cf2827'
    ExternalUID: ''

Select the architecture port inPort on the architecture model and open the Property Inspector from the Modeling menu. Under Open in Interface Editor, select the edit link. In the Interface Editor, enter the Port Interface View. Observe the new data element newElement under the port inPort.

Input Arguments

dataElement — Data element or function argument

data element object | function argument object

Data element or function argument, specified as a systemcomposer.interface.DataElement or systemcomposer.interface.FunctionArgument object.

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Definitions

Term	Definition	Application	More Information
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.	Compose Architectures Visually Author Parameters in System Composer Using Parameter Editor
Root	A root is at the top of an architecture hierarchy. A root architecture has a boundary defined by its architecture ports that surround the system of interest.	The root architecture has a system boundary surrounding your architecture model. You can add architecture ports that define interfaces across the boundary.	Compose Architectures Visually
Model	A System Composer model is the file that contains architectural information, such as components, ports, connectors, interfaces, and behaviors.	Perform operations on a model including extracting root-level architecture, applying profiles, linking interface data dictionaries, or generating instances from model architecture. A System Composer model is stored as an SLX file.	Create Architecture Model with Interfaces and Requirement Links
Component	A component is a 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, another 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 port interfaces using the Interface Editor, and parameters using the Parameter Editor.	Compose Architectures Visually
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.	Component ports are interaction points on the component to other components. Architecture ports are ports on the boundary of the system, whether the boundary is within a component or the overall architecture model. The root architecture has a boundary defined by its ports.	Compose Architectures Visually
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.	Compose Architectures Visually

Data dictionary	A data dictionary is a repository of data relevant to your model. The Architectural Data section of a data dictionary stores shared definitions used in Simulink® and architecture model interfaces, such as port interfaces, data types, and system wide constants. For more information, see What Is a Data Dictionary?	You can save local interfaces on a System Composer model to the Architectural Data section of a Simulink data dictionary using the Interface Editor. In addition to the Interface Editor, you can also use the Architectural Data Editor to manage and modify interfaces and value types.	Manage Interfaces with Data Dictionaries Reference Data Dictionaries Store Shared Data in Architectural Data Section
Data interface	A data interface defines the kind of information that flows through a port. The same interface can be assigned to multiple ports. A data interface can be composite, meaning that it can include data elements that describe the properties of an interface signal.	Data interfaces represent the information that is shared through a connector and enters or exits a component through a port. Use the Interface Editor to create and manage data interfaces and data elements and store them in a data dictionary for reuse between models.	Create Architecture Model with Interfaces and Requirement Links Define Port Interfaces Between Components
Data element	A data element describes a portion of an interface, such as a communication message, a calculated or measured parameter, or other decomposition of that interface.	Data interfaces are decomposed into data elements that can represent pins or wires in a connector or harness, messages transmitted across a bus, and data structures shared between components.	Create Interfaces Assign Interfaces to Ports
Value type	A value type can be used as a port interface to define the atomic piece of data that flows through that port and has a top-level type, dimension, unit, complexity, minimum, maximum, and description.	You can also assign the type of data elements in data interfaces to value types. Add value types to data dictionaries using the Interface Editor so that you can reuse the value types as interfaces or data elements.	Create Value Types as Interfaces
Owned interface	An owned interface is an interface that is local to a specific port and not shared in a data dictionary or the model dictionary.	Create an owned interface to represent a value type or data interface that is local to a port.	Define Owned Interfaces Local to Ports
Adapter	An adapter connects two components with incompatible port interfaces by mapping between the two interfaces. An adapter can act as a unit delay, rate transition, or merge. You can also use an adapter for bus creation. Use the Adapter block to implement an adapter.	With an adapter, on the Interface Adapter dialog box, you can: create and edit mappings between input and output interfaces, apply an interface conversion UnitDelay to break an algebraic loop, apply an interface conversion RateTransition to reconcile different sample time rates for reference models, apply an interface conversion Merge to merge two or more message or signal lines, and when output interfaces are undefined, you can use input interfaces in bus creation mode to author owned output interfaces.
