removeElement

R2026b

Remove element from struct type

Since R2023b

Syntax

removeElement(StructTypeObj,elementName)

Description

removeElement(StructTypeObj,elementName) removes the struct element with the name elementName from the struct type specified by StructTypeObj.

Examples

Configure Struct Elements of a StructType

To configure struct elements of a struct type, use the addElement, getElement, and removeElement functions.

In this example, the dictionary MyInterfaces.sldd contains one struct type.

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

archDataObj = 

  ArchitecturalData with properties:

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

Get the struct type object using the getDataType function. The struct type object contains two struct element objects.

structTypeObj = getDataType(archDataObj,"structType1")

structTypeObj = 

  StructType with properties:

           Name: 'structType1'
    Description: ''
       Elements: [1×2 Simulink.dictionary.archdata.StructElement]
          Owner: [1×1 Simulink.dictionary.ArchitecturalData]

To create a struct element object and add it to the struct type, use the addElement function.

structElemObj3 = addElement(structTypeObj,"structElement3")

structElemObj3 = 

  StructElement with properties:

           Name: 'structElement3'
           Type: [1×1 Simulink.dictionary.archdata.ValueType]
    Description: ''
     Dimensions: '1'
          Owner: [1×1 Simulink.dictionary.archdata.StructType]

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

structElemObj2 = getElement(structTypeObj,"structElement2")

structElemObj2 = 

  StructElement with properties:

           Name: 'structElement2'
           Type: [1×1 Simulink.dictionary.archdata.ValueType]
    Description: ''
     Dimensions: '1'
          Owner: [1×1 Simulink.dictionary.archdata.StructType]

To remove a struct element from a struct type, use the removeElement function.

removeElement(structTypeObj,"structElement1")

The struct type object now contains only two struct elements, structElement2 and structElement3

structTypeObj.Elements(1)

ans = 

  StructElement with properties:

           Name: 'structElement2'
           Type: [1×1 Simulink.dictionary.archdata.ValueType]
    Description: ''
     Dimensions: '1'
          Owner: [1×1 Simulink.dictionary.archdata.StructType]

structTypeObj.Elements(2)

ans = 

  StructElement with properties:

           Name: 'structElement3'
           Type: [1×1 Simulink.dictionary.archdata.ValueType]
    Description: ''
     Dimensions: '1'
          Owner: [1×1 Simulink.dictionary.archdata.StructType]
