Add reference data dictionary to parent data dictionary

Syntax

addDataSource(dictionaryObj,refDictionaryFile)


Description

addDataSource(dictionaryObj,refDictionaryFile) adds a data dictionary, refDictionaryFile, as a reference dictionary to a parent dictionary dictionaryObj, a Simulink.data.Dictionary object.

The parent dictionary contains all the entries that are defined in the referenced dictionary until the referenced dictionary is removed from the parent dictionary. The DataSource property of an entry indicates the dictionary that defines the entry.

Input Arguments

dictionaryObj — Parent data dictionary

Simulink.data.Dictionary object

Parent data dictionary, specified as a Simulink.data.Dictionary object. Before you use this function, represent the target dictionary with a Simulink.data.Dictionary object by using, for example, the Simulink.data.dictionary.create or Simulink.data.dictionary.open function.

refDictionaryFile — File name of data dictionary to reference

character vector

File name of data dictionary to reference, specified as a character vector that includes the .sldd extension. The data dictionary file must be on your MATLAB path.

Examples

Add a Reference Data Dictionary to a Parent Data Dictionary

Open the data dictionary myDictionary_ex_API.sldd and represent it with a Simulink.data.Dictionary object named myDictionaryObj.

myDictionaryObj = Simulink.data.dictionary.open('myDictionary_ex_API.sldd');

Add the data dictionary mySubDictionary_ex_API.sldd as a reference dictionary to myDictionary_ex_API.sldd.

addDataSource(myDictionaryObj,'mySubDictionary_ex_API.sldd');

Confirm the addition by viewing the DataSources property of variable myDictionaryObj. The property returns the name of the newly referenced dictionary.

myDictionaryObj.DataSources

ans = 

    'myRefDictionary_ex_API.sldd'
    'mySubDictionary_ex_API.sldd'
