getDestinationElement
Description
gets the selected data elements on a destination port for a connection.selectedElems
= getDestinationElement(connector
)
Examples
Get Data Element on Destination Port of Connection
Get the selected element on the destination port for a connection.
Create a model and get its root architecture.
modelName = "archModel"; arch = systemcomposer.createModel(modelName); systemcomposer.openModel(modelName); rootArch = get(arch,"Architecture");
Add a component, create an output port on the component, create an output port on the architecture. and extract both component port objects.
newComponent = addComponent(rootArch,"Component2"); outPortComp = addPort(newComponent.Architecture,... "testSig2","out"); outPortArch = addPort(rootArch,"testSig2","out"); compSrcPort = getPort(newComponent,"testSig2"); archDestPort = getPort(rootArch,"testSig2");
Add data interface, create data element, and set the data interface on the architecture port.
interface = arch.InterfaceDictionary.addInterface("interface2"); interface.addElement("x"); archDestPort.setInterface(interface);
Connect the ports and get the destination element of the connector.
conns = connect(compSrcPort,archDestPort,DestinationElement="x");
elem = getDestinationElement(conns)
elem = 1×1 cell array {'x'}

object.
Output Arguments

More About
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. | |
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. | |
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:
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 | 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. |
| |
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. |

---|---|---|---|
interface data dictionary | An interface data dictionary is a consolidated list of interfaces and value types in an architecture and where you use them in the architecture. | You can save local interfaces on a System Composer model in an interface data dictionary using the Interface Editor. You can reuse data dictionaries between models that need to use a given set of interfaces, elements, and value types. Data dictionaries that you link to models are stored in separate SLDD files. | |
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 an interface data dictionary for reuse between models. | |
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:
| |
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, you can perform functions on the Interface Adapter dialog box:
