Syntax

setDictionaryDefault(serviceDict,sectionName,defaultEntry)
setDictionaryDefault(dataDict,categoryName,propName,defaultPropVal)

Description

setDictionaryDefault(serviceDict,sectionName,defaultEntry) specifies the default entry defaultEntry for the service interface section sectionName in the service interfaces coder dictionary serviceDict.

example

setDictionaryDefault(dataDict,categoryName,propName,defaultPropVal) specifies the default value defaultPropVal for the property propName of the category categoryName in the data interfaces coder dictionary dataDict.

Embedded Coder® Dictionary that contains a service interface configuration, specified as a coder.Dictionary object.

Service interface section name, specified as a string scalar or character vector that corresponds to a section of the service interface definitions in the dictionary. Sections include:

  • "DataReceiverInterfaces"

  • "DataSenderInterfaces"

  • "DataTransferInterfaces"

  • "InitTermFunctions"

  • "MeasurementInterfaces"

  • "ParameterArgumentTuningInterfaces"

  • "ParameterTuningInterfaces"

  • "PeriodicAperiodicFunctions"

  • "SharedUtilityFunctions"

  • "SubcomponentInitTermFunctions"

  • "SubcomponentPeriodicAperiodicFunctions"

  • "TimerInterfaces"

The name of the service interface entry to set as default, specified as a string scalar or character vector. To get the available entries for a section, use the find method for the section.

Example: find(getSection(serviceDict,"DataReceiverInterfaces")).Name

Embedded Coder Dictionary that contains a data interface configuration, specified as a coder.Dictionary object.

Data interface category name, specified as a string scalar or character vector that corresponds to a category in one of the category groups in the dictionary, Function Defaults and Data Defaults.

Function Defaults categories are:

  • "InitializeTerminate"

  • "Execution"

  • "SharedUtility"

Data Defaults categories are:

  • "Inports"

  • "Outports"

  • "ModelParameters"

  • "ModelParameterArguments"

  • "ExternalParameters"

  • "SharedLocalDataStores"

  • "GlobalDataStores"

  • "InternalData"

  • "Constants"

Name of category property for which to set the dictionary default value, specified as a string scalar or character vector. The list of available properties to use with this method depends on the category type and its specific configuration.

For categories within Function Defaults, the FunctionCustomizationTemplate property is available for use with this method. When the FunctionCustomizationTemplate is set to Default, an additional property, MemorySection, becomes available for use with this method for these categories.

Data Defaults categories have the StorageClass property available for use with this method. The set of available properties is dynamic and varies based on the assigned value of the StorageClass property. For example, when the StorageClass property is assigned the value ExportToFile, which is allowed for certain categories, these additional properties become available for use with this method:

  • "HeaderFile"

  • "DefinitionFile"

  • "Owner"

  • "PreserveDimensions"

To learn more about storage classes and their properties, see Choose Storage Class for Controlling Data Representation in Generated Code.

Default value to set for the specified property. The value type depends on the property whose value is being specified.

The available values for the FunctionCustomizationTemplate, MemorySection, and StorageClass are those defined in the dictionary, in the sections FunctionCustomizationTemplates, MemorySections, and StorageClasses respectively. To get the list of available values for each of these properties, use the find method in combination with the getSection method. For example, to get the list of available storage class names, enter:

find(getSection(coderDataDict,"StorageClasses")).Name
The available values for other properties depend on the type of property whose value is being specified. To learn more about storage class dependent properties and how to specify their values, see Choose Storage Class for Controlling Data Representation in Generated Code.

Create a Simulink data dictionary that contains an Embedded Coder Dictionary. Create the Embedded Coder Dictionary so that it represents a service interface configuration.

dictionaryFile = Simulink.data.dictionary.create("codeDefinitions.sldd");
codeDictionary = coder.dictionary.create("codeDefinitions.sldd","ServiceInterface");

Get the default receiver service interface.

receiver = getDictionaryDefault(codeDictionary,"DataReceiverInterfaces")
receiver = 

  Entry with properties:

                       Name: 'ReceiverExample1'
                 DataSource: 'C:\work\serviceDefinitions.sldd'
    DataCommunicationMethod: 'OutsideExecution'
               FunctionName: 'get_$X$N'

Get a list of the available receiver service interfaces.

recSection = getSection(codeDictionary,"DataReceiverInterfaces");
receivers = find(recSection);
receivers.Name
ans =

    'ReceiverExample1'


ans =

    'ReceiverExample2'


ans =

    'ReceiverExample3'

Set a different receiver interface as the default.

setDictionaryDefault(codeDictionary,"DataReceiverInterfaces","ReceiverExample2");
Open Live Script

Create a Simulink® data dictionary, then create the Embedded Coder Dictionary to represent a data interface configuration.

dictFileName = "dataDict.sldd";
dataDict = Simulink.data.dictionary.create(dictFileName);
coderDataDict = coder.dictionary.create(dataDict,"DataInterface");

Use the getDictionaryDefault method to see the default StorageClass of the Outports category.

getDictionaryDefault(coderDataDict,"Outports","StorageClass")
ans = 
'Default'

Set the default StorageClass of the Outports category to GetSet. Then specify GetFunction (the naming rule of the get function) as get_outports_$N and specify SetFunction (the naming rule of the set function) as set_outports_$N.

setDictionaryDefault(coderDataDict,"Outports","StorageClass","GetSet")
setDictionaryDefault(coderDataDict,"Outports","GetFunction","get_outports_$N")
setDictionaryDefault(coderDataDict,"Outports","SetFunction","set_outports_$N")

Discard and close the dictionary, then delete the dictionary file. This allows you to run this example more than once without getting an error while attempting to create the dictionary.

discardChanges(dataDict)
Simulink.data.dictionary.closeAll("-save")
delete(dictFileName)
