isConnector

Find if instance is connector instance

Description

example

flag = isConnector(instance) finds whether the instance specified by instance is a connector instance.

This function is part of the instance API that you can use to analyze the model iteratively, element by element. instance refers to the element instance on which the iteration is being performed.

Examples

Load the small unmanned aerial vehicle (UAV) model, create an architecture instance, and query whether the instance modified by the Connectors property is a connector instance.

model = systemcomposer.loadModel('scExampleSmallUAVModel');
instance = instantiate(model.Architecture,'UAVComponent','NewInstance');
flag = isConnector(instance.Connectors(1))

TermDefinitionApplicationMore Information
analysisAnalysis is a method for quantitatively evaluating an architecture for certain characteristics. Static analysis analyzes the structure of the system. Static analysis uses an analysis function and parametric values of properties captured in the system model.Use analyses to calculate overall reliability, mass roll-up, performance, or thermal characteristics of a system, or to perform a SWaP analysis.
analysis functionAn analysis function is a MATLAB® function that computes values necessary to evaluate the architecture using properties of each element in the model instance.Use an analysis function to calculate the result of an analysis.Write Analysis Function
instance modelAn instance model is a collection of instances.You can update an instance model with changes to a model, but the instance model will not update with changes in active variants or model references. You can use an instance model, saved in an .MAT file, of a System Composer™ architecture model for analysis.Run Analysis Function
instanceAn instance is an occurrence of an architecture model element at a given point in time.An instance freezes the active variant or model reference of the component in the instance model.Create a Model Instance for Analysis

TermDefinitionApplicationMore Information
architectureA System Composer architecture represents a system of components and how they interface with each other structurally and behaviorally. You can represent specific architectures using alternate views.

Different types of architectures describe different aspects of systems:

  • Functional architecture describes the flow of data in a system.

  • Logical architecture describes the intended operation of a system.

  • Physical architecture describes the platform or hardware in a system.

Compose Architecture Visually
modelA System Composer model is the file that contains architectural information, including components, ports, connectors, interfaces, and behaviors.

Perform operations on a model:

  • Extract the root-level architecture contained in the model.

  • Apply profiles.

  • Link interface data dictionaries.

  • Generate instances from model architecture.

System Composer models are stored as SLX files.

Create an Architecture Model with Interfaces and Requirement Links
componentA 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 architecture 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.Components
portA 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:

  • 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.

Ports
connectorConnectors 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
