    Syntax

    functionElemObj = getElement(serviceInterfaceObj,elementName)

    Description

    functionElemObj = getElement(serviceInterfaceObj,elementName) returns the function element object with the name elementName contained in the service interface object serviceInterfaceObj.

    To configure function elements of a service interface, use the addElement, getElement, and removeElement functions.

    In this example, the dictionary MyInterfaces.sldd contains one service interface.

    archDataObj = Simulink.dictionary.archdata.open("MyInterfaces.sldd")
    archDataObj = 

  ArchitecturalData with properties:

    DictionaryFileName: 'MyInterfaces.sldd'
            Interfaces: [1×1 Simulink.dictionary.archdata.ServiceInterface]
             DataTypes: [0×0 Simulink.dictionary.archdata.DataType]
             Constants: [0×0 Simulink.dictionary.archdata.Constant]

    Get the service interface object using the getInterface function. The service interface object contains two function element objects.

    serviceInterfaceObj = getInterface(archDataObj,"ServiceInterface1")
    serviceInterfaceObj = 

  ServiceInterface with properties:

           Name: 'ServiceInterface1'
    Description: ''
       Elements: [1×2 Simulink.dictionary.archdata.FunctionElement]
          Owner: [1×1 Simulink.dictionary.ArchitecturalData]

    To create a function element object and add it to the service interface, use the addElement function.

    funcElemObj3 = addElement(serviceInterfaceObj,"functionElement3")
    funcElemObj3 = 

  FunctionElement with properties:

    FunctionPrototype: 'y = functionElement3(u)'
         Asynchronous: 0
    FunctionArguments: [1×2 Simulink.dictionary.archdata.FunctionArgument]
                 Name: 'functionElement3'
                Owner: [1×1 Simulink.dictionary.archdata.ServiceInterface]

    To access an existing function element, use the getElement function.

    funcElemObj2 = getElement(serviceInterfaceObj,"functionElement2")
    funcElemObj2 = 

  FunctionElement with properties:

    FunctionPrototype: 'y = functionElement2(u)'
         Asynchronous: 0
    FunctionArguments: [1×2 Simulink.dictionary.archdata.FunctionArgument]
                 Name: 'functionElement2'
                Owner: [1×1 Simulink.dictionary.archdata.ServiceInterface]

    To remove a function element from a service interface, use the removeElement function. 

    removeElement(serviceInterfaceObj,"functionElement1")

    The service interface object now contains only two function elements, functionElement2 and functionElement3.

    serviceInterfaceObj.Elements(1)
    ans = 

  FunctionElement with properties:

    FunctionPrototype: 'y = functionElement2(u)'
         Asynchronous: 0
    FunctionArguments: [1×2 Simulink.dictionary.archdata.FunctionArgument]
                 Name: 'functionElement2'
                Owner: [1×1 Simulink.dictionary.archdata.ServiceInterface]
    serviceInterfaceObj.Elements(2)
    ans = 

  FunctionElement with properties:

    FunctionPrototype: 'y = functionElement3(u)'
         Asynchronous: 0
    FunctionArguments: [1×2 Simulink.dictionary.archdata.FunctionArgument]
                 Name: 'functionElement3'
                Owner: [1×1 Simulink.dictionary.archdata.ServiceInterface]

    Input Arguments

    Function element name, specified as a character vector or string scalar.

    Data Types: char | string

    Output Arguments
